iMac mid 2011 21,5" I plan to install Mojave/Calatina using a egpu
I want to install macos Mojave/Catalina but my gpu doesn’t support the software, so i was looking into buying a egpu because I do not want to take apart my iMac and I was wondering what the best egpu would be to get. Looking for cheapest but still good performance
@dp301, What software/task are you planning to use the eGPU for? Will you connect an external monitor to the eGPU?
@dp301, buying an eGPU doesn’t allow you to upgrade to higher (unsupported) versions of macOS.

There are eGPU 3 builds that use the iMac 2011:
There's a thread for upgrading the GPU but it's complicated so you don't want to go that way:
You can install Catalina to unsupported Macs but it won't behave well with the original iMac 2011 dGPU?
People have successfully combined #1 and #3.
I haven't seen anyone try combining #2 with #3. I think it should be possible but might take a lot of work? You'll probably have to disable the built-in display.
