been given a iMac to configure for my new job.
Its a 2009 20" iMac. I recently clean installed Mountain Lion, as I knew it was stable and I had a boot USB.
I thought Mountain Lion would be enough but now it turns out I need to upgrade and can only now be Yosemite....
My question is, will Yosemite be too much for my 2009 older iMac with 2GB Ram?
Currently it runs fine, and ram can be upgraded to 4GB but not for a while.
