Mac book pro update ( 2009)
Since I updated my mac book pro to Yosemite, it seems to be slower and hanging more. I have 8 gig of ram and the processor is a 2.53 GHz Intel core duo. So I have a couple of questions the new mac book pro processor are 2.2GHZ, are they faster? Would the performance of my mac improve if I replace the hard drive with an SSD one?
