Hi, newbie here. I searched the forum threads and couldn't find anything on this, apologies in advance if I missed it. Like an idiot, I started "secure empty trash" and trashed some folders that are massive. The computer is getting hot (MacBook Pro 1st gen) and there are a lot - as in thousands - of files to go. I tried stopping the process, shutting down, and it wouldn't let me. Does anyone know how to do this? I'm running OSX 4.11. I know this was dumb. Did it right after a physical therapy appointment while multitasking and I wasn't thinking straight.
