HOWTO: Upgrade Your macOS

HOWTO: Upgrade Your macOS

It is MGB policy to download all current Operating System & software updates for your Mac. Vulnerabilities are discovered frequently in software, and they put your Mac, your data, and the enterprise at risk. To stay protected, ensure that you are running a current, supported Operating System, and that your software applications are up to date. 

To update your Operating System, launch System Preferences > Software Update. Proceed to download and install all available updates. 

Supported Mac Operating Systems

Apple supports their current Operating System and two versions prior. Vendors only release updates for supported Operating Systems, so MGB enterprise services like Email, Citrix, and VPN rely upon a Mac that is up to date. Check your Operating System version from the Apple Menu Icon > About This Mac. The supported Apple Operating Systems are:

  • macOS Big Sur 11.0 (2020)
  • macOS Catalina 10.15 (2019)
  • macOS Mojave 10.14 (2018)

Updates are not released for out of date Operating Systems, so running an Operating System other than those listed above puts you at risk. If you are running an out of date Operating System, open a Service Desk request for assistance with an upgrade.

Backup Your Data

Before updating your Operating System, it is highly recommended that you backup your data. Please follow Apple’s backup guide using the built-in Time Machine.

Determining Application Needs

With Apple’s introduction of macOS Catalina 10.15, older 32-bit applications are no longer supported. Follow Apple’s 32-bit app compatibility guide to determine if you have incompatible apps. The PEAS team has posed Big Sur compatibility information.

Academic apps such as EndNote, FlowJo, GraphPad Prism, MATLAB, SPSS, Stata, etc, can be purchased through the ERIS Core.

Please check with vendors/developers to see newer versions of apps are available if you have incompatible apps. macOS Mojave 10.14 can be installed should your computer contain apps that cannot be upgraded. Please keep in mind that support for Mojave will end in October 2021, as which time your Mac can no longer remain on the MGB network unless it is upgraded to a supported Operating System.

Upgrading Your macOS

After performing backup and determining application needs, you can proceed with the macOS upgrade to macOS Mojave 10.14 or macOS Catalina 10.15.

Update Your Software Applications

Software Applications also need to be kept current to ensure your security and ability to operate in the enterprise. Apps that should be checked for updates include Microsoft Office, Java, Adobe Flash, Cisco AnyConnect VPN client, and any other application you rely upon to conduct business. PEAS Self Service in your Applications folder has all current enterprise software available for download.
