Note

This list is preliminary and some devices may be qualified for Lync, but not supported on Skype for Business on the Mac.Refer to the System requirements for the minimum hardware required.

Legacy Mac clients

Skype for Business Server 2015 also supports the following legacy clients on computers that are running Mac OS 10.5.8 or latest service pack or release (Intel-based) operating systems (Mac OS 10.9 operating system is not currently supported). For details about supported features, see Desktop client feature comparison for Skype for Business.

• Microsoft Lync for Mac 2011 (see Lync for Mac 2011 Deployment Guide)

• Microsoft Communicator for Mac 2011 (see Communicator for Mac 2011 Deployment Guide)

These clients are not supported by Skype for Business Server 2019.

Infrastructure requirements for Skype for Business on Mac

The Skype for Business on Mac client leverages both the Unified Communications Management Platform (UCMP) as well as the Unified Communications Web API (UCWA) that our mobility clients use.

The client has the same requirements as our mobility clients in that you must have an Access Edge Server and Reverse Proxy deployed in a supported configuration.

Authentication

The Skype for Business on Mac client supports Cert-based authentication, Microsoft Modern Authentication, and Multi-Factor Authentication when deployed and enabled.

Note

Due to a current limitation, the user's Exchange credentials must be the same as their Skype for Business credentials.

Certificates

Certificates in use on the Access Edge, Reverse Proxy and Front End servers must not use the SHA-512 hash algorithm.

The HTTP Certificate Revocation List must be defined and accessible by the client. For example, we don't support an LDAP entry in the certificate as your Certificate Revocation List.

DNS

Mobility must be properly deployed for the Skype for Business on the Mac client to function properly. A common failure scenario is to have both of the following DNS entries resolvable on the internal network:

• lyncdiscoverinternal.<sipdomain>

• lyncdiscover.<sipdomain>

For more information, refer to: Deploying Mobility in Lync Server 2013, and the Microsoft Lync Server 2010 Mobility Guide.

Are you having problems using Skype on your Mac? Maybe it’s conflicting with another app, or it shows the ‘quit unexpectedly’ error when you launch it?

This might be due to the associated files and folders of the older version interfering with your downloads. Perhaps something went wrong with the macOS update and you need to completely uninstall your current Skype before reinstalling the latest version.

Maybe you want to delete Skype for a good reason. Perhaps your friends have moved to Oovoo and Discord and you simply want to get rid of Skype from your Mac completely to free up a bit extra storage.

Whatever your intent is, you have come to the right place. We’ll show you how to uninstall Skype three different ways, each with step-by-step tutorials.

The first method shows you how to manually remove Skype from your Mac and reinstall. The other two methods are more efficient but come with the trade-off of installing another app.

Anyway, just choose which method best fits your situation. Let’s get started.

1. Uninstalling Skype with the Traditional Way (Manually)

Note: This method is best suited if you have extra time on your hands and do not mind taking extra steps to do it manually.

Step 1: First, you need to quit the Skype app. You can do this by moving your cursor to the top-left corner, clicking on the menu, and selecting “Quit Skype”.

Alternatively, if you prefer to use Mac shortcuts, hit “Command+Q” on your keyboard. If you are experiencing problems with quitting the app, simply force quit it. To do this, click on the Apple icon and hit “Force Quit”.

Step 2: Delete Skype by dragging it from your Applications folder to the Trash.

Step 3: Remove Skype from Application Support. Go to Spotlight Search at the top-right corner of your screen. Type “~/Library/Application Support” and hit Enter.

You will be directed to the place where all application files are stored. Locate the “Skype” folder and drag it to the trash.

Note: This will delete all your Skype chat and call history. If you want to keep them, skip this step.

Step 4: Remove the remaining associated files. Go back to Spotlight Search at the top-right corner again, then type “~/Library/Preference”‘ and hit Enter.

Now type ‘Skype’ in the search box. This will show you the folders associated with the app. Ensure that your filter is set to Preferences and not This Mac. Proceed to drag the associated folders into the trash.

Step 5: Open Finder and enter “Skype” in the search bar to do a final check on the remaining items related to Skype. Move all of the results to the trash. Then empty your trash to delete all the files.

That’s it! If you do not have the extra time to remove Skype manually, or Skype can’t be uninstalled using this method, try the following methods instead.

2. Uninstalling Skype with AppCleaner (Free)

Best For: If your Mac is not in desperate need of clearing massive storage space and you just need a one-time uninstallation of an app.

AppCleaner, like its name says, is a free third-party uninstaller app that allows you to thoroughly remove unwanted apps in a drag-and-drop manner. We had a detailed review of the app in this article. You will see that on the right-hand side of the webpage, there are different versions to download.

Make sure you check your macOS version first and download the correct version of AppCleaner accordingly. You can do this by clicking on the Apple icon at the top right, then clicking on About This Mac. There you’ll be able to find the info as seen below.

Once you download and install AppCleaner, you will see the main window.

Next, open a Finder window and go to Applications. Proceed to drag your Skype application into the AppCleaner window.

The app will locate all of Skype’s associated folders for you. See? 24 files totaling 664.5 MB in size were found. Then all you have to do is click ‘Remove’ and you’re all set.

Not happy with AppCleaner? No problem! We’ve got another great option for you.

3. Uninstalling Skype with CleanMyMac (Paid)

Best For: Those of you who need to free up more storage space on your Mac — i.e. not only do you want to remove Skype, you also want a list of other apps to uninstall and you want to do this in a batch.

CleanMyMac is one of our favorite solutions. We run the app regularly to clean up our Macs and the app never fails to deliver its promise. In addition, it actually includes a dozen features that allow you to do many things, including uninstalling third-party apps in bulk.

To uninstall Skype (and other apps you don’t need anymore), start by downloading CleanMyMac and installing it on your Mac. Then follow the four steps as indicated in the screenshot above.

On the main screen, click on Uninstaller. The default filter is Sort by Name so everything is listed in alphabetical order. You should easily find Skype by scrolling down.

Done!
