Hey folks..... First post here and a relative newbie to Mac and OSX. My MBP 13 is only about 7 months old and I was loving it after slugging it out with a cheapo Dell running Vista. I'm having problems already though and I'm disappointed to say the least. My problem is my macbook (running Snow Leopard) will not bootup from the power button. It looks like it's starting as normal.... synth tone (or whatever its called), white screen, apple logo.....then the apple logo turns to what looks like a stop/danger sign and it just hangs there with the little timer graphic circling continuously. Whats really puzzling me is that it starts up in safe boot and then if I choose "restart" from the Apple menu, the computer will shutdown and boot up as normal!?!? It just will not start from the power button after shut-down. I've tried running the disk utility verify and repair tools and I get various reports similar to the one pasted below..........although the check disk tool reports that the disk appears to be ok....the repair tool gives various reports similar to this.... "2010-02-22 20:18:00 +0000: Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x . 2010-02-22 20:18:40 +0000: Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired." This is all double dutch to me! The only thing significant thing I did on the computer, that I cant think of that maybe causing problems, was uninstall Norton Security Suite as I'd heard it was usless. So I uninstalled it with an app called appcleaner and installed iAntivirus instead. It seems to be since then that the problems started. Maybe I've deleted some important system files unwittingly along with Norton?? I have previos backups with time machine on an external drive and have both my Leopard and Snow Leopard discs. Can I do restore from a backup or should I reinstall the OS? Sorry this is such a long winded post but I'm trying to include as much info as possible. I hope someone can help as I'm bamboozled. Thanks.
