my macbook is about 5 years old (13 inch mid 2007) and has been very slow lately to the point of freezing up. I have deleted some programs and then I thought it was a disk start up issue, so I have "repaired disk permissions." However, I still have a the same problem. Any ideas? I'm lost... I have updated the macbook to OS X 10.7.3 las summer I think. Processor is 2ghz intel core 2 duo; Memory 3GB 667 mhz ddr2 sdram; HD 188.82 free out of 319.21gb. I'm not computer driven, please forgive me if I have forgotten something. Any help is greatly appreciated.
