I decided to backup my important files.took me 3 days because each click would take ages to be executed. I only had like 3 issues with registry entries I believe. I looked for trouble shooting info and followed the procedures to use disk utility, etc. I would get the WHEEL spinning for over a minute for each click on anything. This is my first time ever dealing with a Mac OS X reinstallation.Ībout a week ago, while working online, my MacBook Pro just started to be very very slow to do anything.
