Choose Upgrades by Serial Number
Choose Upgrades by Serial Number
Search for any Mac model. You can search by name and date, as well as any of various identifiers such as: serial number (Macs made before 2021), part number, model identifier, model number and EMC number.
To search for a serial number, enter the serial number on its own. Other identifiers and keywords can be combined.
You can also search for a macOS version to see all Macs compatible with it.
Once you have found your Mac, you will find detailed specs for it and see fully compatible products, repairs, and upgrades for your exact machine.
You can find your Mac's serial number in Apple System Profiler: Select the Apple Menu > About This Mac, then (depending on the version of OSX you are running) click the System Report button or the More Info button. This brings up System Profiler, and on the Hardware Overview that is displayed by default you should see your serial number, and be able to copy/paste it. The procedure does vary slightly between different versions of OSX.
If your Mac is not working, the serial number is printed on the computer casing but the location varies. Here are the main locations of serial numbers on Apple computers.
More information on finding your serial number is available here on the Apple website.
Choose Upgrades by Model Identifier
Your Mac's Model Identifier can be found in System Profiler. You can use the drop-down menus above to be taken to a page that displays upgrades specifically for your exact model.
This tool is also available on its own page.
