Hi every1

I have a problem hope you can help me with..
This morning when I turned on my machine, it asked me to update some software, such as Quicktime, iTunes, and a few more.
Then, when finished, asked me to reboot, so I proceeded.

Then when booting, on "Starting Mac Os X" screen, the blue bar went really slow and when got to the end, never booted. So I rebooted...
Now it wont load Mac Os x, always stays on "Starting Mac os x" screen for ages (hours)

I tryed the Disk utility, repairing permissions and repairing disk, but no luck.
It says everything looks fine, but doesnt load Mac os X.

Any suggestions??

Thanks, Santi
 
Most likely your machine wasn't hung at all -- you were just a little on the impatient side! ;)

After a major update, your machine may take significantly longer to boot than normal. After those updates you mentioned, my machine seemed to "hang" at the gray screen, then it seemed to "hang" again on the "Loading Mac OS X" screen like you describe -- in fact, it wasn't hung at all, but most likely doing some routine maintenance and updating journal files and what-not. A typical boot on my machine takes less than a few minutes -- after said updates this time, it took over 10 minutes to fully boot, after which it was back to normal speed.

Mac OS X is extremely picky about how it starts up and shuts down -- critical procedures are done during these times that should not be interrupted for any reason... as you found out, interrupting these processes can leave you with an unbootable system.

Best bet is to start from the OS X Install CD/DVD and use Disk Utility to repair your drive -- see how far that gets you. If you still have an unbootable system after that, respond back and we'll take further troubleshooting steps.
 
Thanks for your reply.
I have already tryied to repair disk and permission using OSX Tiger DVD, but it says everything looks fine.
Is there anyway to repair permissions on unix?
I can access hard drive using firewire mode with another mac (key t when restarting) and everything looks fine.
I've been backing up all important data in case my machine finally crash, but I have more than 100Gb so, I would prefer to fix my machine, hehehe

Any other idea?

Thanks guys
