Hey everyone, I have a 2011 MacBook Pro that came with Snow Lepard. 10 days after the purchase I upgraded to Lion. I also upgraded to Mountain Lion when it was released. My Mac is my only machine and I use it daily, but I've noticed that it has somewhat slowed down. Not to say "slow" but I get the beach ball more than I remember and cold app launches have never been longer. It is still a pleasant experience, but not what it seemed 2 years ago. Mavericks is coming soon and I was wondering if a clean install is worth it. Part of my slowness my be due to the fact that I have filled up about 55% of my HDD. I know SSDs are faster, but that isn't an option right now. Would you do a fresh install? I have a time machine backup, but I wouldn't restore from it because I fell like that would simply be putting the same system state back on. I would copy over my iPhoto library, documents and CD music from an external drive amd would redownload my iTunes content and apps. The only hassle would be reinstalling VMWARE and MS office. So, do you think I should do a fresh install? Is my above drag and drop method the best way to restore my content? Any advice on reinstalling VMWARE amd MS office to avoid activation issues? Thank you all so much.
