I've got MB from a couple years ago: Mac OSX 10.6.8 2.26 GHz Core 2 Duo 2 GB 1067 MHz DDR3 But it is hella-sluggish. As a Windows machine is my primary computer, I wrote it off as needing a format/reinstall. After doing that, the machine is still really slow. Even launching a web browser leads to spinning beach balls. Are there any built-in diagnostic utilities in OSX to verify if I have some hardware issues? Or is it time to upgrade the RAM? Thanks!
