Hey there!

Since a while I'm using Monterrey 12.1 on my MacBook Air 13" 2017. I need to be honest, the performance and optimization for this OS is not appropiate for my MacBook Air. Since this upgrading I'm having a lot of performance issues, and I really want to back to the previous version, because it works amazing with my mac.

How can I return to Big Sur? Sadly, I didn't have a Time Machine with that version. How can I do it?

Thanks :)

same as here
