How to Uninstall Node.js from Mac OSX

Just keep in mind that these commands will remove the Node executable, and not necessarily all of the Node projects or NPM cache.

Manually

If you installed Node either by source or from a binary distribution then you'll likely have to delete the executable and other resources manually. Unfortunately, this isn't easy since there are quite a few directories containing Node resources, like npm and node_modules.

To completely uninstall the node executable as well as npm, here are some instructions on what to do:

Note that not all of the directories listed here may exist on your system depending on your install method.

• Delete node and/or node_modules from /usr/local/lib
• Delete node and/or node_modules from /usr/local/include
• Delete node, node-debug, and node-gyp from /usr/local/bin
• Delete .npmrc from your home directory (these are your npm settings, don't delete this if you plan on re-installing Node right away)
• Delete .npm from your home directory
• Delete .node-gyp from your home directory
• Delete .node_repl_history from your home directory
• Delete node* from /usr/local/share/man/man1/
• Delete npm* from /usr/local/share/man/man1/
• Delete node.d from /usr/local/lib/dtrace/
• Delete node from /opt/local/bin/
• Delete node from /opt/local/include/
• Delete node_modules from /opt/local/lib/
• Delete node from /usr/local/share/doc/
• Delete node.stp from /usr/local/share/systemtap/tapset/

This list should include just about all the references to Node on your system. Keep in mind there may be more. Please let me know if you find any others (and how you installed Node originally)!

Homebrew

The Homebrew method is arguably one of the easiest ways to get Node on and off your system. The command to remove it is just as simple as the command to install it. Assuming you used brew install node to install it, just execute this to get rid of it:

$ brew uninstall node

And that's it! All traces of the executable will be gone from your system.

NVM

The Node Version Manager (NVM) is almost as convenient as Homebrew, but in a different way. It allows you to install multiple versions of Node on your system so you can easily switch from one to the other.

Eventually, you'll probably want to get rid of one of the versions when you're done with it. And like Homebrew, you can easily do this using a command similar to the way you installed it:

$ nvm uninstall <version>

And a complete example of this might be something like:

$ nvm uninstall v0.12.2

And now only version v0.12.2 of Node will be uninstalled. Keep in mind that if you had multiple versions installed, then Node will still be on your system, but not v0.12.2 (using the example above).

Phantom Installs

If for some reason none of the above methods worked for you, then you can always hunt down the executable using the command line tool which. This command shows you the location of the file for a given command.

We can use this to find where Node is installed on your system. You can try this with:

$ which node
/Users/Kasinathantechnology/.nvm/versions/node/v4.1.2/bin/node

You can see in the output that my node command is linked to an NVM version, although yours may be located somewhere else. Now I can use this info to uninstall it.

Using this tool should help you find out how the executable was installed or how to remove it manually.

Format an External Hard Drive or USB Flash Drive for Mac OS X

How to Format an External Drive for Mac Compatibility

This is a simple procedure and is achieved the same way for all drive types and through all connections, be they USB, Firewire, or Thunderbolt. Formatting a drive will erase all data and partitions on the disk:

1. Connect the hard drive or USB key to the Mac
2. Launch Disk Utility, located in Applications > Utilities
3. Locate the drive name from the left hand side of Disk Utility and click on it
4. Click on the “Erase” tab across the top

5. Next to “Format:” click the contextual menu and select “Mac OS Extended (Journaled)”

6. Name the drive if you want, the name can be changed at any point
7. Click the “Erase” button and confirm again on the next pop-up window

That’s all there is to it, the drive will now format and erase everything on it.

Smaller external hard drives, SSD’s, and USB flash keys format quickly, while a larger hard drive may take a while longer. When completed, the drive will be formatted to the Mac OS X compatible HFS+ filesystem.

The videos below demonstrate the complete process of formatting an external hard drive for full Mac OS X compatibility, this uses the new Disk Utility in modern versions of OS X:

Similarly, you can perform the same type of process in OS X for making a USB flash drive compatible with Mac OS using the Disk Utility in OS X, as you can see, it’s a quick procedure that is done in short order on any Mac:

Should you intend to make an OS X installer drive or create any other bootable Mac OS X volume from a drive, or use a new drive as a fully compatible Time Machine backup drive, you will also need to complete this process.

How to Rename Your Wireless Apple Mouse, Magic Mouse

As many of you should know, Apple has recently launched a new, Multi-Touch capable mouse - the Magic Mouse. The older mouse didn’t leave the scene as the new one arrived, although Apple is heavily promoting the new peripheral. The two mice have something in common - they’re Bluetooth-capable and work with Mac OS X wirelessly.

Wireless mice are great to use. You feel completely free to handle them any way you want. With Apple mice, the functionality goes above that of traditional mice. They’re even allowed to have their own name, like “John’s Mouse,” or “My Super-Cool Mouse.” But how do you give your mouse a name, or how do you change the name of an Apple wireless mouse, in case you’re the not the first person to use it? This short tutorial will let you in on that secret.

Upon setting up your wireless Apple mouse (whether it’s the former Mighty Mouse, or the new, exquisite Magic Mouse), Mac OS X pairs the device to the computer you’re going to use it with, and automatically assigns it a name. The name is assigned based on your computer’s name (root directory). However, if you want to change it, you can. Here's how.

(don't forget to click on the images for a larger view)

1. With your wireless mouse connected and working, launch System Preferences.



2. For one reason or another, Apple decided not to include the option to rename your paired devices at first glance. So, instead of choosing “Mouse,” choose “Bluetooth.” It should be on the third row down, between “Network and “Sharing.”


3. Once in Bluetooth prefs, select the mouse you want to rename and click the small cogwheel, located under the list of paired devices (the cogwheel is found throughout Mac OS X and typically hides more options).


4. As shown above, select “rename.” A drop-down menu will appear containing a field where you can write down the new name of your mouse - as shown in the screenshot below.


5. Hit OK, and close System Prefs. That’s it!

You can now check out your rodent’s new name by clicking on the Bluetooth icon in the menubar, located at the top right side of your Mac’s screen.

App Store Review Guidelines

Introduction

We're pleased that you want to invest your talents and time to develop applications for iOS. It has been a rewarding experience - both professionally and financially - for tens of thousands of developers and we want to help you join this successful group. We have published our App Store Review Guidelines in the hope that they will help you steer clear of issues as you develop your app and speed you through the approval process when you submit it.

We view Apps different than books or songs, which we do not curate. If you want to criticize a religion, write a book. If you want to describe sex, write a book or a song, or create a medical app. It can get complicated, but we have decided to not allow certain kinds of content in the App Store. It may help to keep some of our broader themes in mind:

• We have lots of kids downloading lots of apps, and parental controls don't work unless the parents set them up (many don't). So know that we're keeping an eye out for the kids.
• We have over 350,000 apps in the App Store. We don't need any more Fart apps. If your app doesn't do something useful or provide some form of lasting entertainment, it may not be accepted.
• If your App looks like it was cobbled together in a few days, or you're trying to get your first practice App into the store to impress your friends, please brace yourself for rejection. We have lots of serious developers who don't want their quality Apps to be surrounded by amateur hour.
• We will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, "I'll know it when I see it". And we think that you will also know it when you cross it.
• If your app is rejected, we have a Review Board that you can appeal to. If you run to the press and trash us, it never helps.
• If you attempt to cheat the system (for example, by trying to trick the review process, steal data from users, copy another developer's work, or manipulate the ratings) your apps will be removed from the store and you will be expelled from the developer program.
• This is a living document, and new apps presenting new questions may result in new rules at any time. Perhaps your app will trigger this.

Lastly, we love this stuff too, and honor what you do. We're really trying our best to create the best platform in the world for you to express your talents and make a living too. If it sounds like we're control freaks, well, maybe it's because we're so committed to our users and making sure they have a quality experience with our products. Just like almost all of you are too.

Living document

This document represents our best efforts to share how we review apps submitted to the App Store, and we hope it is a helpful guide as you develop and submit your apps. It is a living document that will evolve as we are presented with new apps and situations, and we'll update it periodically to reflect these changes.

Thank you for developing for iOS. Even though this document is a formidable list of what not to do, please also keep in mind the much shorter list of what you must do. Above all else, join us in trying to surprise and delight users. Show them their world in innovative ways, and let them interact with it like never before. In our experience, users really respond to polish, both in functionality and user interface. Go the extra mile. Give them more than they expect. And take them places where they have never been before. We are ready to help.

Checklist for Submitting an App to the App Store

Before you can release a paid app to the App Store, you must agree to all of the paid app contracts, and submit your tax and bank routing info. This should be done in iTunes Connect. For best results you should fill this out before you even begin working on any apps, because it can take several weeks for the contracts to be approved by Apple.

Preparation

1. Complete all of the coding and testing on your app.
2. Update the Appname-info.plist file in your app.

1. Set the bundle identifier (if you haven't already) to YourAppName. (Remove the com.apple.whatever stuff.) The Identifier should not contain spaces or funny characters - alphanumeric and dashes are ok.
   
2. If you want your app to be named something different on the actual device than its name in Xcode, change the "Bundle display name" as well.
   
3. Update the bundle version. If this is your first time submitting this app, the version number should probably be 1.0.
   
4. Be sure the icon file is set.
   

3. Build the app for distribution.
4. Write a description for your app for the app store. The app upload page says the description should be 700 characters or less, but that limit doesn't seem to be enforced.
5. Choose a numeric SKU for your app. This can't be left blank, and it has to be a unique number for each of your apps. (I usually use YYMM, like 0902, but you can use whatever you want as long as it's a number.)
6. Assemble your screenshots. You'll need at least one primary screenshot, and up to four more secondary screenshots. Be sure they're the right size: 640 x 960 for high resolution iPhone screenshots; 1024 x 768 for iPad screenshots.
7. Prepare your iTunes artwork. This is a 512 x 512 pixel 72dpi JPEG. It should match your icon artwork as closely as possible - apps are sometimes rejected if these two images are dissimilar.
When you've got all that prepared, you're ready to set up your app in iTunes Connect.

iTunes Connect

When you log into developer.apple.com/iphone, there's a link to iTunes Connect on the right. Once you're logged into iTunes Connect, click on "Manage Your Applications", then "Add New Application".
The app details page asks for your app name, description, copyright info, version number, SKU, application URL and support URL and support e-mail address (all of these are required). The URLs you enter translate to:

iTunes Connect calls it:	What it shows on your app's page in iTunes:
"Application URL"	"CompanyName Web Site"
"Support URL"	"Appname Support"

If this is your first time uploading an app to the app store, and you enrolled as an individual developer, you'll be asked if you want to set a Company Name. Think carefully about this - once you set it, you can NOT change it without calling Apple and going through their phone support line. If you set a company name then all of your apps will show it.
This is also where you should upload the iTunes artwork and screenshots.
Ratings: You'll be asked to rate your app by indicating whether it includes any offensive material.
Pricing and availability: this is where you set the price and release date for your app. You'll get a chance to review this after you select a pricing tier. The page should show a link to the pricing tiers, but if it doesn't show one initially, just set the price to anything and let it refresh. The link should show up then.

Free
Tier1 - 0.99
Tier 2 - 1.99
Tier 3 - 2.99
Tier 4 - 3.99
Tier 5 - 4.99
Tier 6 - 5.99

And so on. Release date: This defaults to the current date, but you can set it to a date in the future* if you like. When your app is approved, you'll want to log back into iTunes Connect and reset the release date to the approval date; that way the app will show up at the top of the new releases section of its category. If you fail to do this, then when your app gets approved it'll show up buried several pages down - not very desirable.

*if you're submitting an app UPDATE, however, you shouldn't touch the release date until you get word that your update has been approved. If you change the release date of an update to sometime in the future, then your CURRENT app will vanish from the app store!

Once you've finished setting up info on your new app, go to the app details page and click on the Ready to Upload Binary button.

Submitting Your App

Starting with Xcode 4, apps are now submitted from within Xcode. You should build a release build of your app, and be sure it appears in the Archived list in the Organizer (Window -> Organizer).

To submit your app to Apple, you'll first need to Validate the app, then Submit it. Select your application from the list of archived apps, then click the Validate button on the right. Xcode will prompt you for your iTunes Connect login credentials, and proceed to validate the app. If all goes well, the Status column will change to "Passed Validation". Then you can click the Submit button to upload it to Apple. When the upload finishes, the Status column will say "Submitted":

Once your app has been submitted, the app's status in iTunes Connect will change to "Waiting for Review". Now you just have to wait for Apple to review and (hopefully) approve your app. This usually takes about a week, sometimes longer. If you log into the iOS Developer Center and go to the App Store Approval Process page, you'll find an App Store Review Status section that Apple keeps (more or less) updated with the percentage of apps that are approved within the past week.
While you're waiting for approval, you should set up a web page for your app.

After Approval

When your app is approved, you'll get an email saying your app is ready for sale. You should log back into iTunes Connect and change your app's availability date to today. This way your app will appear at the top of the "new releases" list in its category. You can only do this on the date your app was approved.
You can change most of the app details any time after your app is approved; if you want to re-word the description, or upload new screenshots, or change the price of your app, you can do so without having to go through the approval process again. The only time you'll have to wait for approval is when you submit an update (a new binary) to an app. Also, you can only change keywords or ratings when you upload a new binary.

Hacking into PhoneGap iPhone/iPad Apps

Initially a lot of web-developers started with PhoneGap which lets you make webpages and embed them inside an iPhone app.

Now similarly its very easy to get access to those web pages. Let me show you how.
Steps:
Get hold of an phonegap iPhone App. I have one, which I had created a long time back.
- So go to – http://www.phonegap.com/apps
- Select iPhone or iPad
- Pick an app for which you want code (Let me pick my application)


- Get the link to the app and open with iTunes

Download the app. It will save the app in your Apps Folder

Right Click on the app and select “Show in Finder”
You will see the .ipa file.
TicTacToe 1.1.ipa
Rename it to
TicTacToe 1.1.zip
Unzip the file and you will find something like this

Right Click on TicTacToe and select “Show Package Contents” – There will be mostly a folder in it “www” which will have the entire HTML, JS and CSS files or whatever the person used.

Mac Terminal Error : Could not determine audit condition

When I launched my terminal today, was welcomed with this error :-

login: PAM Error (line 396): System error
login: Could not determine audit condition

[Process completed]

It is most probably because I was playing with my /usr/bin permissions the other day.
The fix is easy. Just delete the "/usr/bin/login" dir.

But how do I delete it, if I can't access the "Terminal" altogether ?
Come on - You can access any folder using the "Finder".

1. Open "Finder"
2. Open "Go To Folder"
3. Type "/usr/bin/login"
4. Delete it.

Debugging Tutorial – Automating Your Tests With A UIRecorder Instrument

If you have ever experienced a bug in your application that took many steps to reproduce, then this tutorial is for you.  By nature, testing and debugging are very tedious processes.  This is especially the case for the iPhone.
Say you have an app that drills down 5-levels deep to some other view.  Now let’s say that you have a bug on that view 5 levels deep.  Your normal method of debugging is:

• Run the app
• Tap view 1
• Tap view 2
• Tap view 3
• Tap view 4
• Tap view 5
• (Crash)
• Change some code
• Repeat

As you can see (and I’m sure have noticed), this sucks.  Well, Kendall Gelner gave a killer talk at 360iDev (which I recently attended) on various debugging tips using Instruments and XCode.  One of the most useful techniques (to me) was how to automate your testing.  Let me show you what I mean.

1. Open up the app you wish to test/debug
2. Launch it in the simulator
3. Open Instruments – This is located in /Developer/Applications/Instruments (just do a spotlight search for it)



4. Select UIRecorder and click Choose - You should now see a window like this



5. Now, we need to attach this tool to the iPhone Simulator process.  Click the drop-down above  

Default Target -> Attach to Process -> iPhone Simulator.




6. Now click Drive & Record and do all of the steps in the simulator to test your app.  At this point, the UI Recorder is recording your every move.  When you have finished press the Stop button. Note: After you have recorded your actions, don’t move the simulator as it will mess up the entire process.
7. Modify your code…
8. Press the Drive & Record button and watch the magic happen.  The test is automatically done for you.  You should see your mouse move over to the simulator and the system mimicking every action that you did before.
That’s it! I know this isn’t a super long tutorial (or even a coding tutorial), but the UI Recorder has sped my test time up tremendously.  Give it a shot and let me know what you think.  Here is a short video of me going through all of the steps.

Backup iPhone Pictures – Mac Tips

Listen to this episode
When you have problems with your iPhone, you may have no other choice than to RESTORE it back to the factory state. Before you restore, iTunes says it is making a backup of your phone. However, it isn’t making a backup of any photos you have taken with it. So when the phone is restored, all of your photos will be gone. The good news is that If you have your iPhone set to sync your photos with iPhoto automatically when you plug it in, you may be OK. However, if you are like me and choose for the iPhone not to launch iPhoto when you connect it… well, you need to backup those pics.

How to do it:

1. Plug-in your iPhone and launch iPhoto. iPhoto will detect your iPhone, and you can now choose to import all or import selected pictures.

Doing this will add pictures you have taken with your iPhone into your iPhoto library.

Another Way – Image Capture

You can also use Image Capture to do the same thing, but not add them to your iPhoto library.
1. Plug-in your iPhone. Launch Image Capture. You can find it in your Applications folder. If you don’t see it there, look in the Utilities folder. Note: On the podcast, I said it will be in the utilities folder… I forgot that it may reside in Applications.
2. Now it will detect your iPhone, and you can choose to Download Some or Download ALL to your Mac.

Creating Digital Mockups For Your Apps

While conceptualizing your App, the first things you need to create is a flow chart of how your App will behave and some reference templates and images that will show you how each screen will look in your App. Here are some tools to help you do this.
While conceptualizing your App, the first things you need to create is a flow chart of how your App will behave and some reference templates and images that will show you how each screen will look in your App.

The first step to doing this is to get hold of a pencil and paper and make some rough sketches. Start by making a list of all the possible screens your app will have and then actually listing the functionality each screen will have. Once you have that, you can proceed to make some dummy mockup sketches. At this point you should focus on the “placement” elements of each screen… that is decide, what goes where. Next you can start to imagine the design elements and look and feel of each screen – and how they will all look similar and connect to one another. A flow chart showing how the connect up – will help. I suggest you get hold of a spiral bound sketch book and not lose sheets of paper, that can easily get misplaced. Any writing pad will also do.

To help you make your hard copy and soft copy drawings, these downloadable documents and plans will help you. They will be useful when you are brainstorming or trying to find the perfect flow for your app and putting the visual elements together.

• Mock App – Templates for Keynote and Powerpoint

• OmniGraffle Software for Mac – Need a diagram, process chart, quick page-layout, website wireframe or graphic design?

• iPhone Stencils for OmniGraffle

• iPhone Wire Frames for OmniGraffle

• iPhone GUI Elements – Layered image files of iPhone GUI in .PSD format for Photoshop

• More iPhone Interface Elements – more .PSD files for Photoshop

• iPhone UI Vector Elements – Vector format of visual elements and icons in Adobe Illustrator format.

• Yahoo Design Stencils – Yahoo! Design Stencil Kit version 1.0 is available for OmniGraffle, Visio (XML), Adobe Illustrator (PDF and SVG), and Adobe Photoshop (PNG)

Download each of the above packs and files as they are all must have tools when you or your graphic artist are planning the User Interface or graphic design of your Apps.

Installing GIT on OS-X In 3 Minutes

How to install GIT on OS-X in under 3 minutes:

curl http://kernel.org/pub/software/scm/git/git-1.7.1.tar.gz -O
tar xzvf git-1.7.1.tar.gz
cd git-1.7.1
make configure
./configure --prefix=/usr/local
NO_MSGFMT=yes make prefix=/usr/local all
sudo make install

Git should be installed on your OS-X now, which you can verify by issuing: git --version command in Terminal. However, it’s a good idea to also pre-configure the default username and e-mail for your Git installation:

git config --global user.name "Your Firstname Lastname"
git config --global user.email "username@example.com"
git config --global --list

I personally, also like to set:

git config --global color.ui "auto"

How to Setting up the GIT

Setting Up

Now that you have the pre-reqs all ready, you can proceed with the install.  Open a terminal and cd into the directory where you want to install things.  Then type the following (or just copy and paste the items below):

git clone git://github.com/sproutit/sproutcore-abbot.git abbot
cd abbot
rake init
cd ..
git clone git://github.com/sproutit/sproutcore-samples.git samples
cd samples
mkdir -p frameworks
cd frameworks
git clone git://github.com/sproutit/sproutcore.git sproutcore
cd ../..

Add the path to abbot/bin to the beginning of your PATH to be able run the abbot command-line tools (sc-init, sc-server, sc-build, sc-gen, sc-manifest, sc-docs, and more) without having to enter the full path:
export PATH=`pwd`/abbot/bin:$PATH
Make sure you have configured your github account with SSH Keys and Username/Email (Without setting up the SSH key for your machine, you will get a permission denied error when trying to initialize the Git repository)
You should now have the full set of SproutCore tools running the latest Abbot-compatible code.

How to take Screenshot in Mac

In the article you’ll learn how to take screenshot in mac os. Although it’s very easy and quite interesting work but for the new users it’s bit confusing.
But anyways…to take the screenshots in mac os press “Command button +Shift+3″ and it’ll capture & save the image on desktop.
Apart from it there are many more interesting commands to take the screenshot, let’s see below…
1. To select the area and then take the screenshot give following command
“Command button +Shift+4″
2. Press “Command+Shift+4+space” if you wanted to take the screenshot of complete window.
Foregoing commands will save the screenshot at desktop. You can also save the screenshots in to clipboard. To do that you have to press one more button “Control” with the given commands. for example …
Use “Command+ control+ Shift+ 3″ instead of simple
“Command button +Shift+3″ command.
Apart from it mac os provide a software called “Grab” to capture the images in different styles. You can find this software in : Applications->utilities->Grab

Adding a new user account to Mac

Adding a new user account to your computer

You can create individual user accounts for each person who uses your computer. Each new user has a separate home folder and can adjust his or her own preferences without affecting other users.

1. Choose Apple menu > System Preferences and click Accounts.
2. If some settings are dimmed, click the lock icon and type an administrator name and password.
3. Click Add (+) and type the user’s name.
4. If you don’t want to use the short name generated automatically, type a new short name. (Once the account is created, you won’t be able to change the short name.)
5. Type the user’s password in the Password and Verify boxes.
6. Type a hint to help the user remember the password if they have trouble remembering it at login.
7. Click Parental Controls and select options to determine what the user can do with the computer.

If you change your mind while you’re creating a new user account, click Delete (-) to cancel.

How To Easily Share Files Between Mac & Windows Computers

File sharing between Macs and Windows is a little lob-sided. Out of the box, Macs can detect any Windows computer connected to the local network. It appears right on the Finder’s sidebar. So naturally, it is very easy for a Windows user to share their files with anyone on a Mac. The reverse process – allowing a Mac to share its files – requires a little more attention. The transition from Tiger to Leopard has made it a little bit more complicated for regular users to set up shared folders because the setting has been “disguised”.
In this week’s Macnifying OS X, I’m going to show you how easy it is to share files on your Mac so that it appears on Windows computers automatically.




In System Preferences, go to ‘Sharing’ and check the box for ‘File Sharing’. By default, only your Public Folder will be shared. If you want to add other folders to the shared list, click on the ‘+’ sign under the Shared Folder box and choose the folders you wish to share.
After you’re done selecting, you’ll need to set the Permissions for each shared folder. Generally, you should allow Read Only rights to avoid others from messing around with your files. As you can see from the screenshot below, I removed the group labelled ‘Users’ from the users list so only ‘Everyone’ and I appear on the list. I do this to make things easier, only to allow guests logins from other computers.

Next, click on ‘Options’ and on the resulting window, check the box that says “Share files and folders using SMB” and hit ‘Done’.

Now, you’ll need to add your Mac into a Microsoft workgroup. To do this, click ‘Show All’ at the top of the System Preferences windows and click on ‘Network’. Select your active connection and click ‘Advanced’.

In the window which pops up, click on the ‘WINS’ tab and enter a workgroup in the appropriate field. Microsoft has two workgroups: MSHOME and WORKGROUP. Find out which workgroup the majority of your Windows computers belong to and set the workgroup to that.
Click on ‘OK’ and you’ll return to Network preferences, now hit ‘Apply’. Now you’re halfway there – the rest of the work is performed on the Windows machines.

On your Windows desktop, right-click on ‘My Computer’ and select Properties. Click on the ‘Computer Name’ tab and make sure that your workgroup is the same as the one set on your Mac. If it isn’t then click on ‘Change’, set it and restart your computer.
Once that is done, double-click on ‘My Network Places’ and voila, all of your Mac’s shared folders should be visible. Take note that the Drop Box in your Mac’s Public folder won’t be accessible. If you want to use the Drop Box to let other users “drop” their files onto your Mac, you’ll need to change its permissions.
On your Mac’s Home folder, double-click the Public folder. Right-click on Drop Box and choose ‘Get Info’. Click on the lock icon on the bottom right hand corner of the Info window and enter your account password. Then set the permission for Everyone to Read & Write hence, allowing anyone to conveniently “drop” files onto your Mac.

Did you find this tutorial easy to follow? Did it work for you? Is there an easier way to share files between Mac and Windows computers?
