I am planning on going through the process of upgrading the iMac my daughter currently uses.
It suits her needs pretty well, but due to the GPU not supporting the Metal graphics engine, it is limited to MacOS 10.13.x (High Sierra). Unfortunately, most apps on the App Store aren’'t supported anymore.
So after seeing this post on the Mac Rumors forum, I intend to give it a shot.
This should allow me to run a much more modern version of MacOS. Potentially even Ventura. I am going to combine this with a couple other upgrades.
It already has the Core i7 2600 CPU, 16gb RAM and a 500gb SSD. The CPU is the top spec this iMac can support, but they are interchangeable, so if someone has a Core i5 model, they can upgrade that too.
For the upgrades I have ordered an AMD WX7100 GPU, a 1TB SSD, and a new wireless card that will give WIFI AC and Bluetooth 4.
The wireless card will allow for functionality like Airplay and the like to work hopefully.
I have had to order a bunch of adapters, cables, and other bits and pieces to make this work.
Just thought i’d share my plans as maybe someone else is interested in giving it a shot also if they have an old iMac sitting around that could do with a boost.
