Odd you say this... since this afternoon my mac has been pissing me off.... there is a new upgrade to Big Sur operating system... I swear Apple build in 'frustraters' that turn on when a new OS release is out to nudge people to upgrade. Shit like the mouse button randomly stops working, Safari is super slow loading, not being able to eject an external disk, can't open Activity Monitor, can't enter Force Quit.... I am nmo conspiracy guy but I've owned Macs for a long damn time and whenever there is a new release shit just starts going wonky on a machine that has been other wise just fine....
