I tried deleting my old backups from Time Machine by dragging them to the trash. However now I cannot delete them or empty the trash because i now get a multitude of errors. I cannot return them to the Backups folder nor move them to the desktop.
Im at the point of just restoring my machine by reinstalling Sierra. Before I do that I would just like to get rid of the old backups.
How can I fix this?
iMac (27-inch, Late 2013), macOS Sierra (10.12)
