I just replaced my old, mid 2008, 2.1Ghz Whitebook with a brand new 15" 2.53 Macbook Pro. The new one has way faster RAM, 20% faster processor, and newer hardware. So how come it doesn't feel any faster. Safari 4 still takes a second to load up, and Lightroom and iTunes don't feel any speedier either. I think the Whitebook was faster when it was new than this one feels now. I did do a new OS X install when I bought it and transfered my old data using Time Machine. So i guess my question is whether or not some settings from my old account on the macbook, are slowing things down now. For example maybe some Library or System setting/preferences got replaced or something. Even if I am just crazy.... does anyone have any suggestions for starting the computer with the cleanest slate but still keeping my old backup data? I am only interested in backing up music, photos, bookmarks, and thats about it. But that is also about 100GB of data. I don't mind reinstalling Apps rather than restoring them, if it means a cleaner OS X. I probably dont need to worry as much, since I'll be doing a re-Install when Snow Leopard is released, but in the mean time Id like to notice a difference in the computer hardware. Any suggestion??? p.s. I do love my new computer! 15" is way worth it compared to 13" but it still feel weird moving around, unpacking from my bookbag because of the size. The illuminated keyboard is a Godsend though, and Firewire 800 is dreamy fast compared to Firewire 400. I just want to treat this one nice, keep the OS clean and the computer running optimally. See I never shutdown, I only put to sleep usually, restarting once a week at most. I never have more than 5 programs running, and if I'm using Photoshop, than usually even fewer.
