Following on from my previous two articles, I ran further tests on my MacBook to see how it performs under different RAM and different versions of OS X and against an original Intel iMac.

In this comparison I look at how OS X 10.6 Snow Leopard compares when running my Early 2009 MacBook with 2 GB vs. 4 GB RAM, and I see how Snow Leopard compares to OS X 10.9 Mavericks.
