My iMac 2.66 running 10.6.8 runs fine. But when I restart or boot up from shutdown, it takes a good 10 - 15 minutes of blank gray screen to reach the gray apple. Once there, it goes quickly to the login screen and all is well again.

 

Having searched these discussions, I've tried the following with no success:

 

•Safe Boot

•deleted from Login Items

•Zapped the PRAM (possible clue: I can only do it once; when I continue to hold down the keys for an additional 2 minutes or so, nothing more happens after that first Zap. PRAM battery problem?)

 

Any other ideas?


Mac OS X (10.6.8)

    Interesting,

     

    A few questions before we do anything:

     

    1. Can you check if your HDD is in good health? Go to Application> Utilities> Disk Utility. Click the hard drive name (which is the manufacturer's model). What does the SMART Status report? If it says, verified it means that your computer is fine; if not your HDD is about to die and you should back up your data immediately.
    2. Did you checked your disk permissions? See this article, and this one.
    3. How's your Hard Drive available space? Keep in mind that OS X (and most other OSs) like at least 15% free space to do their work happily.
    4. How much RAM you have installed? Is it all being used up while you are logged in the computer?
    5. Did you checked the directory ownership? Run the following command and post your results here. Do this by copying the command below and launching Terminal from Applications> Utilities

     

     

    sudo ls -al /

     

     

     

    Hope this helps!

    Yes, smc reset.

     

    Boot from your installer dvd and run Disk Utilty to repair/verify your drives (not repair permissions).

     

    See how fast booting is when all unnecessary periphials (firewire's, usb's) are disconnected.

    Turns out the problem was my powered USB hub. Pulled it out and the iMac started right up. Man, did I waste a lot of time!

    Don't you just hate it when that happens?

    YES!

     

    I've used that device for 3 years without a problem. Well, I've learned the same lesson for the thousandth time: Look for the one thing that can't possibly be the problem and you will find the solution.
