OS X help

I'm posting from Tom's computer.

I've been trying to reboot my computer for 2 hours now.

This has happened before, I'm pretty sure I know what's wrong but I don't know how to fix it.

An overview:

1. Computer crashed.

2. I restarted it. Computer proceeds through 'grey apple/cog' screen, shows
the 'osx is starting up' screen, then goes directly to a blank blue screen, but still shows a mouse cursor.

3. The computer thinks that a user is still logged in and so won't display the login dialogue that should follow the 'osx is starting up' screen.

4. Previously, I fixed this by asking the computer to start in safe mode. The computer will not boot into safe mode at present. I hold down the shift key, as you do to get safe mode, and the computer proceeds to hang up at the 'grey apple/cog' screen. (This isn't me being impatient, I gave it 1/2 hour this last time.)

5. I can however, boot into single user mode. I fsck'd the disk and it came back clean, so I can only assume that it is still the failure to log out previous user upon crash.


With all that in mind, especially noting that safe mode seems to be inoperable, how would you 'force' the computer to give the login dialogue?

Many thanks and such be upon anyone with ideas.

When this happened to me a couple of years ago, there was a file that I was able to delete by SSHing in from my laptop that solved the problem. No idea if this is what you're seeing, though.

Perhaps something in here will help...? http://discussions.apple.com/search.jspa?q=startup%20blue%20screen&rankBy=10001&start=15

Good luck!

I buzzed around those forums a lot last night. The end result seems to be that I'll need to reinstall the os at some point. What a bother.

I have most things backed up on .Mac, but the papers that I just finished aren't there and I'm loathe to lose them.

I'm not sure what you mean by SSH, though. Thanks.

Being unix, there are lots of things you can do with it just like any other unix machine. Such as set it up to allow you to log in to a shell prompt, ftp in, access it as a webserver, etc. Even if the console is locked up.

I'm pretty certain it's not on by default (it'd be the first thing any unix hacker will enable when they switch, and probably the last thing a pre-OS X mac user would), so you'd be out of luck on that front. However, if you can boot into single user, you can likely enable the networking, and ftp your essays off to another machine

However, try dropping the battery out for a while, while it's sitting at the blue not-logging-in screen, and not plugged in. Maybe that'll persuade it that it shouldn't try and reuse an old session.

Yes, peecees, widely known for their ability to not lock up randomly, nor require regular reinstalls.

My XP Desktop has not required any maintenance, updates or reinstalls in almost 8 months.

Of course, I haven't actually turned it on in this time ;)

Can't help with this much, but I see you on Aberdeen Blogs. Welcome :)

if you get something like this you can take your HD out of your laptop, connect it to the electronics inside the case (can be easily removed from the case) and plug it into one of your other macs, via usb. You should then be able to get your documents and stuff off (or indeed browse the disc looking for the file that you need to delete to get it working again without a reinstall). I've got one, if you fancy a trip down here at the weekend :)

Or you could ask gravy/darkmoon, see if they have any ideas ...
