Some people say turn on “Project Setting → Metal Write-Only Backbuffer” can solve the problem,but I couldn’t find this option in unity 2021 plus.

In 2021 it’s in project settings - player - other

sorry,it’s a Clerical error,I’m using unity 2021,but no “Metal Write-Only Backbuffer” in unity 2021.

Try 2021.3.5f1 maybe?
Maybe it’s lower down?

What I’m using is 2021.3.5f1,I’m trying to reinstall another version to see if that option can appear

Can you tell me which version you are using and give me a screenshot with that option?

I was using 2021.3.5f1. Sadly I don’t have the mac anymore since my semester ended
