Ever since I loaded SL I have been having issues with my Macbook Pro (I didn't do a fresh install). Entourage crashes all the time, and so does word and excel. I have sluggish performance opening windows, and now iphoto is stuck and I cant upload or change any of my flickr sets! I get the beach ball WAY more than I ever use to. I have everything backed up via time machine, but I some questions about reloading. Firstly, how easy is it to restore from time machine? All I really care about is everything in my home folder, all my bookmarks and OS settings (if possible), my itunes music (FINALLY go it all organized and all duplicates deleted) and my lightroom catalog. I lost the disk for lightroom somehow, and I have over 120GB's of pictures loaded in it. I REALLY dont want to loose all my changes to my RAW files. Can I retreive the program with catalog still intact from time machine? Secondly, I have the SL upgrade disk. Can I do a clean install from it? What else do I need to know? I want to do a fresh install to wipe all the clutter off the drive. Can I just do a fresh install, load over everything from my home folder and then Itunes and lightroom? This is my First Mac (had it about 6 months) and I'm paranoid about loosing my stuff. Especially all my images and lightroom catalog!
