How to find your serial number in software
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 you can't boot your Mac
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.
Unibody MacBook Pro - Laser etched onto the base.
MacBook, Early MacBook Pro, PowerBook G4 - Inside the main battery bay. Remove battery to locate.
iBook (White) - Under the keyboard. To lift keyboard, pull back on the release tabs between the F-keys.
Intel iMac, iMac G5 - Underside of the foot/stand.
iMac G4, iMac G3 - Underside of the iMac.
Mac mini - On the underside of the Mac mini.

Compatible Internal Hard Drives & SSDs for this Mac
Internal Drives: your options explained - Click here for more info
The hard drive or solid state drive is where all your documents, data and applications are stored permanently.
Below this box are all the drives we do that are guaranteed 100% compatible with this Mac, based off the Serial Number or Model ID that you have selected.
The list below is divided into sections for the main types of drives, which can include:
Solid State Drives (SSDs) - large chunks of Flash memory used for storage, the fastest and most reliable option, but also the smallest and most expensive.
Hard Disk Drives (HDDs) - the standard rotational drives used in older Macs. Big and cheap, but much slower than SSDs and subject to mechanical failures that do not effect SSDs. These have a spin speed measured in Revolutions Per Minute (RPM), with higher numbers being faster operating drives.
For more details on the differences between these drives, please see this post on our blog.
With most Macs there are lots of options for having more or faster storage, and many can take multiple drives so you can mix and match SSDs and rotational hard drives to find your ideal combination of size, speed and budget. Some Macs have more than one main drive bay, and many Macs can use our range of caddies to replace their DVD drives with additional hard drives or SSDs. Some Macs also have additional drive bays that can be used with a mounting kit. If you have multiple types of bay in this Mac, you can select them with the grey tabs below this box.
It is very important with all system drives (that is, a drive that you boot from) to leave a good amount of free space to allow the system to work well. We recommend leaving around 20-30GB of free space on the system drive, The closer you get to full on your system drive, the slower the Mac will perform.
A 1TB drive can hold:
Up to 1,000 hours of digital video
Up to 250 two-hour DVD films
Up to 320,000 digital photos
Up to 16,660 hours of digital music
All drives come blank and will need to be formatted (erased), and if they are to be a boot drive, have an operating system installed. There are a variety of ways of restoring your data, either through time machine or by cloning.
We sell drives, tools, enclosures and cables for you to do the work at home (see the "Cables, Adaptors & Tools" tab above), or you can send/bring your machine to us for us to do the work - prices all below. However you do it, you can be sure you are getting the correct part with our 100% compatibility guarantee.
