MacOS 10.12 Sierra Not Allowed on Bryn Mawr College Network After 1/14/20; MacOS 10.15 Catalina Released

Posted October 16th, 2019 at 4:07 pm.

MacOS 10.15 Catalina has been released. After January 14, 2020, computers running macOS 10.12 Sierra will no longer be allowed on the Bryn Mawr College network.

With the recent release of macOS 10.15 Catalina, Apple will stop providing support macOS 10.12 Sierra. Ending support includes no longer rolling out security updates to combat the latest cyberthreats.

Beginning this month, LITS will be reaching out to staff and faculty currently using macOS 10.12 Sierra to initiate a plan for their transition to a new operating system or other solution. However, if you are running 10.12 Sierra, please feel free to reach out at any time.

Should I upgrade to macOS 10.15 Catalina?

LITS currently recommends waiting to upgrade to 10.15 Catalina. With Catalina, Apple has ended support for 32-bit applications, as well as iTunes. If you upgrade, 32-bit applications will no longer run properly on your computer. LITS will address these changes more thoroughly in the coming months.

For more information about Catalina or 32-bit apps, please see our earlier announcement: http://lits.blogs.brynmawr.edu/9174

How do I know what version of macOS is on my computer?

To find out what version of macOs is on your computer, click on the Apple icon in the upper left corner of your screen. From there, click on “About This Mac.” You can see what version your computer is running under the “Overview” tab.

What happens if I’m running macOS 10.12 Sierra?

If you are running 10.12 Sierra, please contact the LITS Help Desk at help@brynmawr.edu or 610-526-7440 to schedule a consultation. A LITS representative will then work with you to assess your best course of action and assist in the transition. If you opt not to change your operating system, your computer will not be allowed on the Bryn Mawr College network after January 14, 2020.

Again, please contact us if you’re still using macOS 10.12 Sierra and would like to schedule an upgrade to a newer version of macOS: help@brynmawr.edu or 610-526-7440.
