Do macs slow down over time or am I just hallucinating. For months now my mac starts going crazy with the hard drive buzzing away even just loading web pages. IIRC back in 2008 when I bought this Mac Pro it would be able to open loads of apps at once really fast now it just struggles opening Mail App. I have to force quit photoshop to actually close photoshop or it just hangs for minutes clicking away thinking whatever it thinks. I have never experienced SSD but it seems like my 7200rpm hard drive just turned into a 5RPM hard drive in the last two months :\ thoughts?
