iMac 27" mid 2010 as External Display for a MacBook Air M1

Hi Mikaelo,

No. This is not possible. M1 Macs and macOS Big Sur do not work with Target Display mode.

An excellent display choice is: LG UltraFine 4K Display - Apple.

Cheers,

Jack

Yes, I saw what he said. 😎

Technically that's correct. It wouldn't be Target Display Mode. There are certain limitations. However, it is possible to use a 2010 iMac as a display.

You don't have to of course.

Actually it may be possible if your 2010 iMac has a mini-Display port. There are a couple YouTube videos explaining how.

Well I tried to help. I can't make people listen. 😎
