When will macOS Big Sur reach its end of life?

There's no reason you can't upgrade your 2014 MBA to Monterey. It will support that version of the system. All MBAs from mid 2013 and newer can run Monterey.

Are you having problems trying to install Monterey? You do need at least 50 GB of free space to upgrade, more is possible.

The last security update for macOS High Sierra was November, 2020. Mojave has been receiving regular security updates. If this trend continues, then macOS Big Sur should reach end of life in 2024.

Uhm, Monterey requires a 2015 MBA.

Just learned a valuable lesson: don't take anything on face value. MacTracker has this for 2013 and 2014 MBAs:

and the latest release is Monterey. I thought I'd received an update to the app after the public release of Monterey but must have been mistaken. The link "Latest release of macOS" gives you

As I said: don't take anything on face value. 😔

Your question has been answered. You can also continue to use that Mac with Big Sur until the hardware fails, though there will be opportunity costs in current security and application support.

Hiya Phil. When I was just here your post wasn't listed. That's the second time that's happened to me.

No worries. It happens. Sometimes it takes a while for posts to appear.

Not usually 30 mins. 😎
