How to identify my iMac
How many models of iMacs are there?
Lots! The original ‘Gumdrop’ plastic cased iMac was released in 1998, and came in a variety of funky colours. If you watch any US film or TV series from this period, you’re sure to see the unmistakable form of an early iMac showing up somewhere. With it’s innovative design, usability and clever product placement, the iMac is credited with turning the fortunes of Apple around. In this article, we’ll concentrate on ‘the modern era’, 2009 onwards. 12 years is centuries in computer history.
How do I find my iMac model?
Assuming that your iMac is still functioning, the easiest place to start is here:
- Navigate to the Apple icon on the top left hand corner of your screen
- The ‘Overview’ panel will appear. Click on ‘System Report’, take a screenshot and consult the list below
- On an older OS that doesn’t display an overview, click on ‘More Info’ This will open a panel that displays the hardware overview for your iMac. Take a screen shot, and consult the list below
If your iMac doesn’t start up, the original packaging may also show an Apple part number, such as MMQA2xx/A (“xx” is a variable that differs by country or region). You can match the Apple part number to one on the list below to find your model.

Thinking of buying an iMac from new? Think different.
Apple are working hard to reduce their carbon footprint, but computer manufacture is notoriously carbon and rare earth heavy - not to mention the sumptuous packaging!
We all have a part to play in maintaining the environment we live in. By buying a refurbished iMac we are collectively reducing the overall technology carbon footprint and preserving the planet now and for our future generations. A good refurbished iMac is both a sound economic and ecological choice.
