How to deal with a scam alert that my iMac computer is locked
I have received constant loud, repetitive alerts that my computer is locked and to call their provided Apple Support phone number to unlock it. I did not follow their suggestion; instead I called the real Apple 800 contact number. Very helpful! However, when it happened again, I tried to read "Block Pop Up ads and Windows in Safari". There were numerous steps which I have difficulty in following. I am an elderly person who is not very technologically literate.
iMac 21.5″, macOS 14.0
