Mac Tonic has appeared, already open on my MacAir. Dragging it from applications to trash doesn't work because the Ap is open. is there any way to delete it?
MacBook Air, iOS 11.4.1
Use the force quit option in Activity Monitor.
Otherwise boot into Safe Mode, Mac OS X: Starting up in Safe Mode, as that prevents any 3rd party software from running and you should be able to delete those files.
Thanks. I got it removed before your suggestion but appreciate the help
Restore them from the backup.
Unfortunately, he did not configure time machine.
