cosrocket Posted February 26, 2016 Share Posted February 26, 2016 (edited) A friend of mine has a mid 2007 Aluminum iMac (Model Identifier 7.1), with a Core 2 Duo processor and 4GB of RAM, original HDD running OS X Snow Leopard 10.6.8. There are some programs which say they will soon be unsupported on this version of OS X (like Chrome), so he asked me if he should upgrade to El Capitan. So what I would like to know is if El Capitan should run OK on his iMac, and if not, what is the latest OS X version he should upgrade to that will allow his iMac to last a year or 2 longer and be able to run the latest software without getting non supported software warnings Thanks in advance for your input.

zhangm Supervisor Posted February 26, 2016 Supervisor Share Posted February 26, 2016 It should run fine. I've updated a similarly dated iMac to Yosemite. It takes a while for things to "settle down" when logging in, but I've seen no significant issues. As a refinement on Yosemite, I'd expect El Capitan to be as good or better in terms of performance.

BobSlob Posted February 26, 2016 Share Posted February 26, 2016 He should be fine, but expect longer bootups. This could be countered with a SSD, a highly recommended upgrade. Link to comment Share on other sites More sharing options...
