[QUOTE="dtravis7, post: 1818707, member: 8287"] I own and still use for basic things that very 20" iMac. In fact typing on it right now. Runs El Captain fine but could use a bit more RAM but 6GB is all it can take. Like others have asked, where did you get the OSX versions you are trying to install? Machine specific DVD's will not install except on the machine they were made for. If you downloaded from apple and made an installer Flash drive and you get the Prohibited symbol, the HDD might need to be formatted in DU. Otherwise maybe the hard drive has issues. Many of those machines used a 320 GB WD drive and those tended to die. [/QUOTE]
