WHAT’S HAPPENING: Apple officially released the next version of macOS called Catalina (macOS 10.15) to the public on October 7, 2019. UCSF IT recommends *NOT* upgrading to macOS Catalina (10.15) until the operating system has been fully tested for compatibility with UCSF systems and standard software. We expect testing to be completed by the end of December 2019.

WHAT YOU SHOULD DO: Please *DO NOT* upgrade to macOS Catalina (10.15). The Catalina installer will be blocked from running from the Mac App Store on UCSF IT Field Services (ITFS) managed Macs until macOS Catalina is supported by ITFS.  UCSF IT will make another announcement when macOS Catalina is supported at UCSF.

If you still have macOS Sierra (10.12) or older installed on your Mac, we recommend that you upgrade to the current ITFS supported version of macOS Mojave (10.14).  Apple will most likely stop providing software updates or critical security updates for macOS Sierra (10.12) and older versions with the release of macOS Catalina (10.15). Additionally, Symantec, Dell, Box, Microsoft, and other software vendors may stop supporting macOS Sierra (10.12) and older soon following Apple's full release of macOS Catalina (10.15).

This table shows the current support status of macOS at UCSF, including personally-owned and/or self-supported Apple computers running security software provided by UCSF:

Operating System (OS) OS Version Apple Release Date UCSF IT Support Status Start of UCSF IT Support *End of UCSF IT Support
macOS Catalina 10.15 10/7/2019 Testing Pending  
macOS Mojave 10.14 9/24/2018 Active (Current) 1/15/2019  
macOS High Sierra  10.13 9/25/2017 Active 2/13/2018  
macOS Sierra 10.12 9/20/2016 Phasing Out 11/17/2016 Pending
Mac OS X El Capitan 10.11 9/30/2015 End of Life 12/22/2015 1/15/2019
* Apple typically discontinues maintenance and support of macOS that are more than 2 versions old.  For example, with the release of macOS Catalina (10.15), Apple discontinued maintenance and support of macOS Sierra (10.12) which requires UCSF IT to end support of it as well.

ADDITIONAL INFORMATION: UCSF IT has begun some initial testing of common UCSF applications on Apple's full release of macOS Catalina (10.15). Testing results are being posted on the UCSF IT wiki page at (UCSF MyAccess login required).  Application compatibility status on the macOS platform in general can also be looked up in RoaringApps (non-UCSF affiliated website) as well.

If you have any questions about upgrading your Macs to the current supported version macOS Mojave (10.14.6), please contact the UCSF IT Service Desk at 415-514-4100.
