Password not working

Ok. In that case, your MacBook Air has an Intel processor, and also has the Apple T2 Security Chip.

I doubt whether this will work, but try starting up in Single User Mode: Hold down Command-S as you turn on or restart your Mac. Release the keys when one of the following appear:

• If you see white lines of text on a black screen, you successfully launched Single User Mode. Wait for the text to stop moving, then type "exit" without the quotes and hit Enter (Return) to launch normal macOS.
• If the login screen immediately appeared, enter your password to continue. Then, look for one of the other two signs.
• If you see the Apple logo (or your user account picture) and a progress bar instead, Single User Mode did not launch on your Mac.

Hi Support-not,

Have you tried connecting to a different Wi-Fi network? This might help in reaching the Activation Lock servers.

Also, does your Mac contain the Apple M1 chip?

Ok. If your MacBook Air was made in November 2020 or later, it has the M1 chip. Otherwise, it has an Intel processor.

If it has an Intel processor, what year was the Mac made in?
