CIT Suggests Delaying macOS Catalina (10.15) Update


The CIT Desktop Support Group have identified several issues with Apple’s recent macOS Catalina (10.15) update that affect important managed client applications. For this reason, CIT recommends that administrators use Jamf to disable users’ ability to self-upgrade their devices to Catalina and advise users attempting to apply the update to delay doing so for at least one to two months.

For assistance in disabling users' ability to self-upgrade their devices to Catalina please contact CIT Desktop Engineering at md-mac@cornell.edu.

Some details on managed applications affected by the macOS Catalina include:

  • Crowdstrike
    The vendor has not announced official support for the update.
  • Code42
    As with the macOS Mojave (10.14) update, when updating to Catalina, Mac users must provide Privacy Preferences Policy Control approval for Code42. This approval can be performed using Jamf – see the Jamf webpage Preparing Your Organization for User Data Protections on macOS 10.14 for User Data Protections on macOS 10.14, or contact CIT Desktop Engineering at md-mac@cornell.edu about using Jamf for this approval.
  • Net-Print
    The installer for setting up print queues for the first time with Net-Print is currently not compatible with the latest version of macOS, Catalina. However, if a print queue is already installed on a Mac and it is upgraded to Catalina, the queue will continue to work. If you have upgraded to Catalina or have a new Mac and want to install the print queue, you should contact the IT Service Desk. A workaround is available and can be used until a new installation package is available.

If you have comments or questions about issues with the macOS Catalina update, please contact md-mac@cornell.edu.
