A while back I posted about some of my Apple gripes, one of them being that my MacBook Air M1 and Dell USB-C display wasn’t getting along. A Mac OS update broke it, then another update fixed it. And it remained working until the other day when another Mac OS update broke it again. UGH!
I tried a few things to fix this, until I came across this reddit post which said to cut power to the monitor and plug it back in. I had rebooted the computer a few times but hadn’t thought to do the same with the display and — bam, everything is working again.
Phew! And ugh! Sometimes I hate modern tech.
