iMac 2007 - Mid 2009 RAM


iMac 2007 - Mid 2009

In 2007 Apple redesigned the iMac into an all new silver case, replacing the previous white model that had shared its looks with the old PowerPC iMac G5. The 17" screen model was also dropped, keeping just 20" and 24" options.

Internally all these iMacs have SATA 300 drive controllers, making SSD upgrades useful (with a transfer rate of over 250MB/s). The 2007 and 2008 models however use DDR2 RAM, while the 2009 upgraded to DDR3 and is also the first model to take up to 8GB of RAM. The difference in RAM speed is not huge, but DDR3 an awful lot cheaper, and 8GB is probably the minimum amount of RAM you want to consider to make a Mac effective. For this reason we make 2009 the cut-off of machines we would recommend upgrading in any circumstances. Even with the 2009, it's only for a machine to do lightweight tasks, where the lack of a modern operating system is not an issue - they can be fairly zippy with a small, cheap, SSD and 8GB of RAM, but they are only going to get more out of date. The 2008 and 2007 we consider obsolete and no longer recommend upgrading.

We have been repairing these Macs since they were new, and can still source parts for them if needed. It is unlikely that many repairs will be economically viable however (in terms of getting a machine back that is worth more than the cost of the repair).

All these Macs can run up to OS X 10.11 (El Capitan).
