Login window

macOS Sonoma user login screen

At the login window, enter your user account password to log in to your Mac. If FileVault is turned on, this also unlocks your disk. You might see a default desktop picture in the background, which might change to your chosen desktop picture when you select your account. The login window appears only after you log out of your user account (Apple menu  > Log Out) or restart or start up your Mac. Learn what to do if you forgot your login password.

If you're currently logged in to your user account, you might see your lock screen instead. Your lock screen looks similar and uses the same login password, but doesn't provide password-reset options.

Activation Lock or system lock PIN code

  • If your previously owned Mac shows an Activation Lock window that asks for someone else's Apple Account, the previous owner may need to remove Activation Lock for you. Learn about Activation Lock on Mac.

  • Your Mac might ask for a PIN code when it has been remotely locked using Find My because the owner thinks the Mac is lost or stolen. Enter the four-digit or six-digit passcode to continue.

Display icon with warning symbol

A large display icon with a warning symbol against a dark background on your Apple Studio Display means that your Studio Display is in recovery mode.

Thunderbolt, USB, or FireWire symbol

A large Thunderbolt No alt supplied for Image, USB No alt supplied for Image, or FireWire No alt supplied for Image symbol against a dark background means that your Mac is in target disk mode.
