Hello, Recently i bought iMac 17' (late 2006). Right now it has OS X 10.7.5. I want to install something newer, something which is still supported. I read many guides https://forums.macrumors.com/threads/os-x-el-capitan-on-unsupported-macs.1889851/ but I want to have a graphic acceleration. Can you help me with this ? It is possible ? I've installed the 10.9 but it was quite slow without graphic acceleration. I know that my CPU is 64bit and I have a Radeon X1600.
