You can find more information about your MacBook Air in System Report, in Apple
Diagnostics, and through online resources.
System Report. To get information about your MacBook Air, use System Report. It shows
you what hardware and software is installed, the serial number and operating system
version, how much memory is installed, and more. To open System Report, choose
Apple menu > About This Mac, then click System Report.
Apple Diagnostics. You can use Apple Diagnostics to help determine if there’s a problem
with one of the computer’s components, such as the memory or processor. Apple
Diagnostics helps to identify the potential source of a hardware issue and provides first
steps to try and resolve it. Apple Diagnostics will also help you get in touch with
AppleCare Support if you need more help.
Before using Apple Diagnostics, disconnect any external devices, such as a hard disk or
external display. Be sure the MacBook Air is connected to the internet.
