When Skype online first launched, you could use it for instant messaging and to share multimedia files, but not as a VoIP tool. To make voice and video calls in most supported browsers, you needed to install a plug-in. While the plug-in is available, it's unlikely you'll need it on modern web browsers. Skype for Business is trying to keep you in the center of the sent video with the Crop and center my video in meetings feature that, by default, is turned on. If you want to disable this functionality, go to Tools Video Device settings, and clear the Crop and center my video in meetings check box.

Cornell Skype for Business has been retired in advance of Microsoft's shutdown of the service.

By default, Skype will start automatically when Windows starts. You can change this setting.

  1. Run Skype for Business.
  2. Click the gear icon to open the Options dialog box.
    (If you click the arrow next to the gear, you will need to select Tools, then Options.)
  3. In the list on the left, click Personal.
  4. On the right, under My account, you'll see a checkbox for Automatically start the app when I log on to Windows.
    Check this to have the app start automatically.
    Uncheck this to prevent the app from starting automatically.
  5. Click OK.

While many Mac users may prefer Apple’s FaceTime, Microsoft’s Skype is the most popular platform for connecting people on Macs with those on PCs, Android devices, or tablets. Many of us have been using it for years, or at least have had it on our Mac for years, without giving it a second thought.

However, if it starts misbehaving or you realize it's taking up space on your Mac that you want to recover, it may be time to uninstall it. Uninstalling Skype then reinstalling it may also fix problems that the update can’t resolve. So, in this article, we’ll show you how to uninstall and reinstall Skype. We’ll also look at how to do the same with Skype for Business, the Skype edition designed for use by large organizations.

How to uninstall Skype on Mac?

Skype started life as a way for people to make voice over IP (VOIP) calls from their computers. It allowed us to make calls from computer to computer for free. You can also call regular landline and mobile numbers. Over the years, Skype became a popular tool for making audio and video calls from lots of different devices, including smartphones and tablets.

If it crashes or doesn’t work properly, the best solution might be to uninstall Skype and start again. Also, Skype installs lots of different files on your Mac that take up space, so if you’re not using it, it might be best to uninstall it.

Uninstall Skype – super quick removal

Before I show you how to uninstall Skype from your Mac manually, I want to introduce a really easy way to remove it and all of its associated files with just a couple of clicks. I’ve been using CleanMyMac X for a while, and its Uninstaller module comes in handy when removing programs from your Mac.

  • Download CleanMyMac X, then follow the on-screen instructions to install it.
  • Launch CleanMyMac X from your Applications folder.
  • Choose the Uninstaller module from the sidebar on the left.
  • Select Microsoft in the Vendors category.
  • Check the box next to Skype.
  • Press Uninstall.

You may ask: why would you need an app like CleanMyMac X if you can drag and drop an app to the Trash? The reason is, by simply moving an app like Skype to the Bin, you only remove the program. Its data and leftovers are still left on your Mac, taking up space.

CleanMyMac X removes Skype and its leftovers – all at once. But, if you want to do it manually, here’s how.

If Skype doesn’t work the way it should, you can reset the app without removing it from your Mac. CleanMyMac X lets you do that using the Uninstaller feature. Just locate Skype in the list of apps, check the box next to it and select Reset from the little drop-down menu. Press Reset to confirm and Skype will be running smoothly.

The first steps for removing Skype for Business are the same as those for Skype – quit the app and drag it from the Applications folder to the Trash. However, Microsoft recommends removing the rest of the files using the Terminal. Here’s how to do that.

  2. Type sudo rm -rf /Library/Internet Plug-Ins/MeetingJoinPlugin.plugin
  3. Press Return
  4. Type defaults delete com.microsoft.SkypeForBusiness || true
  5. Hit Return
  6. Then enter each of the following locations, one at a time, pressing Return after each:

    7. rm -rf ~/Library/Containers/com.microsoft.SkypeForBusiness

    rm -rf ~/Library/Logs/DiagnosticReports/Skype for Business_*

    rm -rf ~/Library/Saved Application State/com.microsoft.SkypeForBusiness.savedState

    rm -rf ~/Library/Preferences/com.microsoft.SkypeForBusiness.plist

    rm -rf ~/Library/Application Support/CrashReporter/Skype for Business_*

    rm -rf ~/Library/Cookies/com.microsoft.SkypeForBusiness*

    sudo rm -rf /private/var/db/receipts/com.microsoft.SkypeForBusiness*

    rmdir ~/Library/Application Scripts/com.microsoft.SkypeForBusiness

    find -f /private/var/db/BootCaches/* -name 'app.com.microsoft.SkypeForBusiness*' -exec sudo rm -rf {} +

  7. The last step is to remove the Skype for Business login from your keychain. Go to Applications > Utilities and launch Keychain Access.
  8. Search for Skype for Business in your login keychain and delete it.

As with the regular version of Skype, it’s much quicker and easier to remove Skype for Business by using a dedicated uninstaller like CleanMyMac X.

If that doesn’t work, try restarting your Mac in Safe Mode. This will eliminate the possibility that other processes that launch automatically are preventing Skype from uninstalling. To do that, restart your Mac and hold down the Shift key. Release Shift when you see the Apple logo. When you’re done, restart normally.
