slow boot, 3 min. of blue screen

Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys ?

*A few suggestions:*



If you have not already done so, disconnect all devices from your MBP & run the Hardware Test. The AHT is on System DVD #1 *(the one that originally came w/the MBP).* Read the DVD label to find out which key to boot up from to run the Test.

============

Check your *Starup Items* settings. Disable or remove any items you do not need.

===========

Boot from your Install DVD & run the *"Repair Disk"* option.

Safe Boot by restarting your computer while holding down the "shift" key. Safe booting disables all nonessential processes, often times allowing you to start up when you would otherwise crash.

As of OS X 10.5.6 Safe Boot deletes the dynamic loader shared cache location in the /var/db/dyld directory. A corrupt cache here can cause the blue screen issues. Once you restart normally, the cache will be recreated. This should take care of the issue.

Take your computer to an Apple Store. The staff will be able to check to determine if your model MacBook Pro is experiencing some sort of hardware issues. Logic board?

Hi D,

Any changes just prior to the issue starting? New RAM, HD, spill, drop, etc?

mmmhhh i was also looking for suspicious trash in preferences. how did u manage to think it was that corrupt file?

Hi c,

The safest way to test for things like this is to create a backup clone (CarbonCopyCloner or SuperDuper! or Time Machine), make sure it's totally current, and then you can go in and do things that you wouldn't normally do; if you create more problems, then you can just clone the pre-problems backup back to your internal HD and you're back to where you started. I learn a lot this way (not all of it good! 😉 ). I have multiple backups, and I'm still freaked out when I move/trash/change something and my Mac won't boot. 😟 Then it's just a matter of cloning back or restoring things from TM.

Sweet! Works like a charm. And to think the lady at the service centre replaced my hard disk because of this. Well thanks everyone!

In my case, I just have a blue screen right away on my early 2008 Mac Pro. Deleted the "DirectoryService" folder *_DID NOT_* fix the problem. I'm quite afraid of installing it for my MacBookPro6,1. I wish there was an easy fix...
