I was setting hot corners in Desktop & Dock. All corners work except the upper left corner does not function with any of the choices. Not critical but annoying
iMac 24″, macOS 15.3
I have no idea why the functions would work in all the corners except for the top left.
Try booting into Safe Mode then restart normally. Sometimes that will fix anomalies.
Start up your Mac in safe mode - Apple Support
Did the safe mode start, rebooted but that corner does nothing even though was selected to start screen save (and other)
The lower left corner activates the screen saver so I am just going to chalk it up to a "bug" to live with
What is it set as?
I tried all the options for the corner (the same list of options apply to all corners)
Well, it's not a "bug" since all the Hot Corners on my Macs running Sequoia 15.3.2 work fine. Maybe someone will have an idea why yours doesn't.
Just to add, I actually have the top left corner set to start the screensaver on my M3 iMac.
One hot corner doesn’t function
