My father has completely destroyed two M1 iMac installs so far. YMMV.
He watches YT videos all day and is paranoid about everything. End game was he managed to install two different VPN packages on one install and managed to install a system cleaner on another and spend about £500 in total and end up with two non working systems and higher blood pressure.
I think at this point he needs an iPad in a rugged case with screen time turned on and all his credit cards taking away. Possibly locking his hands in a box somewhere where they can't curse anything as well.
