Factory reset iMac 2013
When into system preferences, there is no option for factory reset. Looked at all YouTube videos but the settings are missing. I believe my iMac has been compromised.
iMac 27″, macOS 10.15
iMac Pro 2013 1TB. No option to factory reset to sale.
I did all steps I found on Apple Support as I have a later version of macOS being a later model desktop Mac, pro 27 . No portion or setting for reset wipe
clean ? Any help would be great thanks .
