Subject: Mac OS upgrade coming Friday

An upgrade to the Mac OS, similar to the one we recently pushed out for Windows 10 will be deployed this Friday. Please forward the below pertinent information to your departments. Thanks!

In order to ensure Apple computers running macOS are kept secure we must proactively upgrade those computers running versions of macOS for which Apple is no longer releasing security updates (i.e. end of life.) Historically Apple has released one major version of macOS per year. Each major release is given a version number and a name. 10.13 "High Sierra", 10.12 "Sierra", 10.11 "El Capitan", 10.9 "Mavericks", etc. Apple only provides security updates for the three most current macOS releases. This means that currently the only Apple supported versions of macOS are 10.13, 10.12, and 10.11. Once the new 10.14 version of macOS is released later this fall then macOS 10.11 would go "end of life" in terms of being supported by Apple.

When a given version of macOS is about to go "end of life" KU IT Support Services will target those computers running that specific version of macOS and deploy an upgrade application to those computers. The exact date/time of the deployment will be communicated to central and non-central technical staff on a per-release basis. The goal for the date of the upgrade is to choose a time where the fewest number of interruptions would occur (most likely in-between academic sessions or during holiday breaks.)

The upgrade application its self has been designed to be as flexible as possible as to when the actual upgrade happens. Once the upgrade has been deployed to those computers targeted for an upgrade the logged in user will receive:

In this example we will be upgrading to macOS High Sierra version 10.13. The user is given the option to defer this upgrade up to 10 times, with 24 hours between deferrals, amounting to a total of 10 days for which the upgrade can be deferred.

Once the upgrade is allowed to continue the machine will immediately restart to complete the upgrade.

The restart could take some time depending on the speed of the hardware and what version of macOS you are coming from, but typically takes under an hour.

If no user is logged into the workstation when the upgrade policy runs then the computer will run the upgrade immediately.

Any workstations running unsupported versions of macOS will begin to see a prompt for an upgrade starting on Friday, September 7th.

Please direct any questions to your IT Support staff.
