Hey, everybody what's up. I've had my Aluminum MacBook since Dec 2008 and the last time I did a clean install was August of 2009 when Snow Leopard came out. It's been about eight months and my Mac is starting to feel a little bit slower. Not a lot, but too a person that spends a lot of time on the computer, the difference is noticable. My question is if I do I clean wipe of my system and re-install OSX Snow Leopard will I be able to recover all my programs, documents and preferences from my time machine back-up, or is Time machine only for when you lose something and you need it back. I know this sounds like a stupid question, but I just don't know what to do. Thanks for reading!
