I currently have Yosemite on my Early 2009 iMac. This iMac has a 2 GHz CPU and 2 GB of ram. However, whenever I try to run Xcode 6 on this Mac, it is slow-very slow. When monitoring my cpu, it hovers around at most 25% use when I'm running it. However, the RAM is using 1.99 GB out of 2.00 GB. My question is will my slow Xcode problem be solved by upgrading my iMac to 8GB of RAM?
