It’s easy to forget details about your Mac—what precise model it is, how much memory is installed, and so on.

Obvious, we know, but it’s essential to remember when talking to tech support or trying to determine if you need more storage or can add more memory. Click each button at the top to learn more about your Mac’s configuration or, in the case of Support and Service, to get links to information from Apple.
