MacOsX 10.5 Blue Screen Please Help!

Hi, I just signed up for this forum and I need some help with my Mac. I have a 15 inch MacOSX 10.5.8 with 2.4G Hz and Core 2 Duo. The computer was working fine all day and I have been using this computer for over a year with no problems.

Today, I changed some of my Permission Settings for viewing from Everyone to No one, Admin Only, and the System (I forgot the subcategories of the Permission Settings). Then, I put my computer to sleep. When I tried to get back on, I got a black screen on which I could sometimes see the mouse. I tried to find out what was happening, but I finally decided to reboot it.

Now I see the Gray Apple start up screen everytime I restart, which then always turns to the blue screen. I can see the mouse sometimes, but it always disappears. There's nothing but blue on the screen except for the loading wheel which periodically comes on and off.

I have looked up some ways to fix this already, but none of them work. I've tried entering the codes and removing the Application Enhancer thingies from the Single User mode, I've tried Safe Booting, and I've also tried booting it from the CD.

Right now I am trying the Archive and Install. I'm really hoping it works, otherwise any other suggestions would be great!

I have really important stuff on that computer, and I don't have a recent back up disk or Time Capsule, so I don't want to erase everything.


Please Please Please Help! School starts really soon, and I really need my computer.
Thanks a lot for your time!

Right. Archive and Install should save your data. That you can boot up on the DVD and do that means you do not have a hardware failure--I have had the serendipitous "Frell the Volume" and Hard Drive death!

That should do it. You should now considering the following for the future:

1. Spend $100: I need the beer [Stop that!--Ed.]. EX-HDs are VERY inexpensive and this panic should more than convince you of the need. HAD you had one you could have simply booted up on it, fixed everything, laughed, continued surfing for that goat porn, et cetera.

Now you have nothing! Okay, A & I should fix the problem, but realize you could have fixed it faster. As far as I know, Time Machine does not make a "bootable" clone. So I recommend SuperDuper! which will allow you to boot directly from the EX-HD and save you from this crap. Further, you can set it for quick back ups of what you have changed.

2. Spend ~$90: For DiskWarrior. Why? There is a small chance you can one day develop an error in the Volume of your Int-HD which you will copy with a back-up. Such errors tend to get worse. True Story: that happened. I discovered it when I ran a maintenance program Onyx . . . then confirmed it with TechTools. Fortunately, I had backed up two days before.

Examining the Ex-HD, I realized that it, too, had an error, but it was less involved, and DW fixed it.

That may seem like a lot of $$$ for just that potential problem, I understand. However, another reason is it can, literally, "take a picture" of a failing drive. On the odd chance your drive starts to fail--and all drives fail eventually--and you did not get a chance to back up that dissertation--DW will allow you to make a Disk Image of your HD which you can transfer and even burn to a disk. Then you can later save your data.

3. Spend ~$10-20 If you are interested in security, get the "Missing Manual" book for your OS. Since Snow Leopard [PBUI--Ed.] is coming out soon--with new book as well--these should drop to very cheap. This will explain simple things like setting a password, setting permissions such as you do not wipe yourself out, and even setting a firmware password--so some prat cannot simply erase your HD or boot from another drive if they steal your computer. If fear of theft is a concern, there is another great program I can recommend.

--J.D.
 
If Misosoup changed the user permissions on the hard drive to 'no one', then an A&I won't solve that. You need to reset the permissions through the terminal before you'll get access to the hard drive.
 
Thanks for the advice! DeltaMac was right, the Archive and Install did not work. I'm going to try to reset the permissions today, and hopefully solve the problem.

Thanks again. :)
 
using single user mode, and did the following:
/sbin/fsck -fy
(return)
waited for the results and then:
/sbin/moun -uw /
(return)
waited for results
chmod -R 777 /
return

after that I restarted and....voila! hahaha. Oh happy day!!!!:)

Thanks everyone for this thread and help.
