This is my first post but I've followed all the existing advice kind folk have provided in the FAQ and previous posts from people who've had similar problems with the SL upgrade on a MBP. Sadly, I still need help! Since running the upgrade, if I boot from the internal drive, my machine brings up the login window but then takes me to a 'Milky Way' desktop that never displays the command bar at the top, tool bar at the bottom, or Internal Drive incon. In fact, the only things that work are the cursor and pad. Everything seemed to be fine up to the point where I got the Welcome dialogue after the install. I figured all my settings were still OK, so I ignored the individual icons for mail settings etc and hit the Continue button. Maybe that was a mistake. Since then, I've rebooted several times from the DVD and repeated the upgrade process. I've also removed the battery and held down the power button, zapped the PRAM etc etc. Any suggestions what I try next? BTW, this is a MBP1,1 with 2.16MHz Intel Core Duo and 2GB memory. It's a lovely machine and I just wish I'd left the OS alone!
