I cannot access emails or websites or even use the mouse on my 2015 MacBook Pro
my 2015 MacBook Pro is not letting me sign in. A rectangular box keeps appearing on my screen, asking me for a keychain password. I have never used a keychain password on my MacBook Pro. I don’t know why but now I can’t access my emails or websites. Does anyone know how to fix this problem?
MacBook Pro 13″, macOS 11.7
