My 2012 MacBook Air has hit the end of line for OS updates. It was left out of MacOS Big Sur compatibility. Over 7 years and still (quite) strong. The only issue is the cute 4GB RAM.

Macs compatible with macOS Big Sur:

• 2015 and later MacBook
• 2013 and later MacBook Air
• Late 2013 and later MacBook Pro
• 2014 and later iMac
• 2017 and later iMac Pro
• 2014 and later Mac mini
• 2013 and later Mac Pro

Eh, on a side note, I’ve just upgraded my phone to iPhone 11, coming from iPhone 7 it’s a big upgrade (I’ve been using Nokia 7.1 for about 4 months along the way though). Couldn’t be happier with its performance, camera, and battery life!
