With Apple’s announcement that older intel macs would be orphaned, I decided to try to get linux working on it before HAD to.
My problem appears to be driver and hardware detection failure as I have no sound and no webcam.
This situation smells like the t2 situation discussed for those macs newer than 2018, however mine is older.
Can someone point me the the correct direction, I’m struggling to find something to read that makes me confident I’m in the right place.
pointers appreciated please
