SERIAL NUMBER

If your Mac doesn't finish starting up

If you can't use the solutions above because your Mac doesn't finish starting up:

• Look for a serial number or model name on the outside of your Mac, or on its original packaging, receipt, or invoice.
• Or sign in to appleid.apple.com, then look for your Mac in the Devices section. If you see your Mac there, click its name to see the model name and serial number.

If you still need help, contact an Apple Store or Apple Authorized Service Provider.

• Find the serial number printed on the underside of your Mac, near the regulatory markings. It’s also on the original packaging, next to a barcode label. You can then enter that serial number on the Check Coverage page to find your model.
