Time Machine back up using external hard drive....
My macbook pro mid 2012 totally shut down on me after updating to High Sierra (10.13?) After safe reboot and “fixing” my disks didn’t work, an option I had was to buy a new hard drive but after scouring the internet, I want to restore my mac using Time Machine and my external hard drive. Will restoring my mac with the external wipe the external drive after I’ve restored my mac?
