Trouble with finder and time machine
My external drive was nearly full so I went to the finder and tried to delete old time machine backups. They seemed to go to the trash, but now I cannot shut down my computer because finder is perpetually trying to empty the trash. I clicked on the x to "stop" the operation, and even though the x is now grayed out, nothing seems to happen. I have figured out how to correctly now delete items from time machine but can't do it because the trash is in a state of perpetual "stopping" . . . Help!
