Hi everyone, some time ago I read something about manually erasing time-machine backups simple by going to the place where the backups exist and drag and drop them to the trash and erasing them. I was low on storage so I did it. The thing is there were some locked system items in there. Locked items that I cannot erase, when I try to I get that warning message saying if I want to delete them, I press yes, then it starts erasing and eventually gets to negative erasing items, I already left it overnight to continue erasing but it was of no help. I can't get the option to put back, and dragging and dropping them outside the trash only makes a copy of them. I just want to get rid of waiting a lot before trying to erase other items and that full trash can. Thanks in advance!
