Support for macOS Mojave ends Nov 30; upgrade to Big Sur

To maintain information security at HMS, we will no longer support macOS Mojave after November 30, 2021. We will continue to support macOS Big Sur and Catalina. Find out which version of macOS you are using by following Apple’s instructions. 

Note that with any major OS upgrade, some of your existing applications may be affected. If you have any questions before upgrading to Big Sur, or if you want to upgrade to Catalina, contact your local IT support team.   

To upgrade to macOS Big Sur: 

  1. Back up your Mac using Time Machine.  
  2. Open the macOS Big Sur page in the App Store
  3. Select Get to download the installer. 
  4. After the download is complete, the installer opens automatically. 
  5. Follow the prompts to install macOS Big Sur. 

 

We still strongly recommend not installing macOS Monterey (the operating system that follows Big Sur) until Apple and app developers address bugs that often accompany major new versions of the operating system. We will contact you when we recommend upgrading, after any potential bugs have been addressed. Until then, use one of the operating systems supported by HMS IT
