Hi after updating to 10.8.3 i'm stucked in the grey boot screen.

Booting in verbose mode shows me

disk0s2 : media is not present


in single user mode if i launch fsck -yf it shows me:


Failed to  issue COM RESET succesfully after 3 attempts. Failing..

disk0s2: no suck device




update/reload mount for / failed: Device not configured


The only way to make the system active is to boot with TARGET option and select the disk.then it boots properly..


any help how to fix that s°*T of update?

Thank you

OS X Mountain Lion (10.8.3)

    Hold Command and R keys while your Mac is starting to start in Recovery HD. Then, open Disk Utility, select your OS X partition on the sidebar and verify the disk. Is it OK? If not, repair it.


    If it doesn't show any problem, the update damaged the operating system. Close Disk Utility and reinstall OS X. You won't lose anything you had stored before updating.


    Sometimes, problems like this happen after a OS X update, and we don't know exactly their reasons. Maybe a third-party extension, maybe a corrupted OS X package, maybe a hard disk failure. To prevent problems like yours, I recommend to install a maintenance update as OS X 10.8.3 downloading the Combo version from the Apple webpage. This version gives less problems than the version you download from the App Store and it can be used to update all your Macs downloading that update once

    thank you for support

    already done all the things you have mentioned...but still the same error..

    i've just downloaded the full combo update on another PC..any idea on how to install it?

  • mende1 Level 10 Level 10 (91,910 points)

    You have to start in OS X to install it. Have you tried to verify the disk using Disk Utility? If not, do it.


    Anyway, I hope that you have a backup, because you may have lost everything you had stored on the hard disk

    Yes i have tried to verify eith disk utility and all seems to be ok.

    I'll try to do a fresh install in some way and let's see..

    thank you again

    If you have a backup, I recommend you to erase the hard drive and reinstall OS X. Definitely, it seems like a very serious problem, if the reinstallation without erasing the hard disk hasn't worked

    I am sorry to hijack this post but I am having the same issue. I even reinstalled the OS and everything worked fine until updated to 10.8.3 again. Is there a solution for this or we should bypass this update?

    I suppose that you erased the hard drive, right? If not, do it. If you did it, I would consider a problem with your Mac. Have you got any external drive connected to your iMac?

  • thunderace Level 1 Level 1 (0 points)

    Full fresh install wiped out everything. I didn't even used my backup, just installed 10.8.3 update. I get a grey screen. Verbose mode output "still waiting for root device".


    I have no external drive connected.

    restored to 10.8.2 from time machine worked fine.

    Updated with combo update to 10.8.3 presented the same issue


    restored again to 10.8.2 worked fine

    so It's quite obviuos that the problem is within the 10.8.3.

    it's a little bit ridiculous that after so many betas some users have this really seriuos issue..

    i really hope in an update as soon as.


    oh yes i have an MBP 15" 2,53 Core 2 Duo  mid 2009

    Hi there


    I'm having a crisis too and I think it's the same problem. I've just updated my Mac Pro from 10.8.2 to 10.8.3 and since then my 2 monitors stay black. I tried reseting the PRAM, nothing then put it into sleep mode and several times took it out of sleep...all of a sudden on the reboot I managed to get the screens to light up. How do I fix this? It's driving me nuts....

    Just to add I tried rebooting from the original system disc and again it didn't work...

    Your boot drive has failed and needs to be replaced.

    But I tried rebooting from the CD..I could hear the drive starting up normally but the screens were you think my video card may have failed?

    Did you upgrade the system with a third party SSD?  You may need to upgrade the firmware on that SSD.


    I had this issue with an Intel X25-M I put into my system, and a firware update resolved the issue.
