I got my 2.0 Ghz MBP (with 2GB RAM) on Tuesday. I was very excited, like all the other new MBP owners, and eagerly booted up and used the Migration Assistant to "clone" my old G4 PB contents to the new machine. When I finished I found it was really, really slow. Whether starting a new app (Universal or not), loading a Web page, quitting an app, or even trying to reboot, the MBP basically acted like it was full of molasses or something. It was essentially unusable. I even made a new user and booted into that account, so it was devoid of any of my old PB junk, and found the same was true. Loading Safari after a clean boot took nearly 40 seconds. I was horrified. I ultimately wiped the MBP's hard drive and reinstalled the OS X from the start. Before migrating any files I tested the basic apps at that point and found Safari, iTunes, Mail, etc. were all quite speedy after the reinstall. I then used the Migration Assitant to again move my PB files over and everything continued to be just peachy fast. It's now two days later and I love my MBP. It's fast, the screen is great, I like the new AC adapter, the battery life is fine, and I'm not noticing the famed hissing LCD sound. But I keep wondering, "what was wrong with it out of the box?" Does it have a genetic condition that might reappear? Does anyone have any ideas on what the problem was? Thanks!
