So, a few weeks into using my newly #Ubuntu powered mid-2011 #Mac and I'm still very much enjoying it. Knew that the RAM on the machine was a bit wanting (even still, the OS runs fast). So I opened up another same model Mac I have to repurpose some RAM. Discovered that I've been running the Ubuntu machine on only 4gb and the other Mac on 16. So now the Ubuntu machine has 12gb and continues to feel like I've purchased a brand new computer.
