What's the highest version of OSX for an iMac6,1
I have an iMac6,1 and I tried to put Mavericks on it, but it said it can't be installed on this computer. Reading online, it looks like Mavericks will only go on iMac7,1 and higher. But I'm having trouble finding out what the highest version of OSX is that I can actually install on this iMac6,1. Can anyone point me to an article that shows this?
