Video of what's happening on my 2017 imac. Basically yesterday I noticed my dock isn't working right. I've had it set to 'hide' automatically so I'd have more screen room and that's worked great for years... but as of sunday I couldn't get it to pop up. So I go in the system prefrences>dock and disable the auto hide. I'm now seeing that the magnification doesn't work either despite being enabled properly.
I followed the troubleshooting tips of going in terminal and using
killall Dock
defaults delete com.apple.dock; killall Dock
I rebooted in safe mode and it still doesn't work correctly. I'm even noticing in FCPX I can't hover my mouse over a part of the track and let it "skim" with the video and audio following where my mouse is.
Any ideas what is going on? I'm on 10.15.2 and haven't touched any settings in ages. Thank you!
