popole77 Level 1 Level 1

Hello everybody,

I did the mountain lion upgrade a few days ago, and since then, I have a few crashes a day.

Does anyone suffer from the same issue? How do I resolve this?

Never had this issue before, and now it seems that It's something that will not solve itself..

What happens is that all of a sudden, I am getting a black screen, and everything is shut down.

Then I'm getting a gray screen saying that there was an error and that my computer is restarting.


Like I said, it happens now a few times a day.



Any ideas?

Thanks for your help guys!!

Didn't mean to create such a mess.


If you're referring to the nastiness that keeps getting removed by the moderators, not to worry, none of that is your doing. 


But here I am... still here.. just had another crash.

After the clean installation.


Well, there's a problem...  Either the installation wasn't actually clean (meaning erasing the hard drive and reinstalling from scratch), or you used Setup Assistant or Migration Assistant to move too much from the backups to the new system, dirtying it in the process.  I say this because your kernel panic log still contains the following:

loaded kexts:

org.virtualbox.kext.VBoxNetAdp          3.1.6

org.virtualbox.kext.VBoxNetFlt          3.1.6

com.parallels.kext.prl_vnic          7.0 15104.778994

org.virtualbox.kext.VBoxUSB          3.1.6

com.parallels.kext.prl_netbridge          7.0 15104.778994

org.virtualbox.kext.VBoxDrv          3.1.6

com.parallels.kext.prl_hid_hook          7.0 15104.778994

com.parallels.kext.prl_hypervisor          7.0 15104.778994

com.parallels.kext.prl_usb_connect          7.0 15104.778994


So that means that all the Parallels and VirtualBox kernel extensions are still installed.


Sorry to be the bearer of bad news!    But is the system working well enough now that you could run the VirtualBox and Parallels uninstallers?

I just went to the VirtualBox site, and I see that the version you're using is more than 2 years old!  That may very well be the culprit.  I downloaded version 3.1.6 for myself from the following link:


Inside that disk image is a file called VirtualBox_Uninstall.tool. You would need to open that script, which will run it in the Terminal, to uninstall VirtualBox.  Note that it will complain about the app being made by an unregistered developer...  you will need to go to System Preferences -> Security & Privacy -> General and temporarily toggle the application control from the default "Mac App Store and identified developers" to "Anywhere."  After uninstalling, switch that setting back to where it was.

    It may be an incompatible piece of thrid party software that opens up via your login items.


    firast thing I would do is to go to your login items via the user/accounts section in system preferences and remove them all. then restart and see what happens.


    you should then also creat a new user account and see what happens....


    Let me know hat hapopens and we will take it from there

  • popole77 Level 1 Level 1

    Hey Ivan,

    Thank you so much for your quick reply!! it's much appriciated.


    I've removed all the login items from my user and restarted.

    Now I'll wait to see if there are any crashes.


    If the crashes will remain, I'll create a new user, and followup again.

    I'll keep you updated.


    Thanks again!

  • Ivan Clarke1 Level 2 Level 2

    No problem, lets hope it solves the issue.

  • popole77 Level 1 Level 1

    ok, just had another crash so I guess that the issue is not resolved yet.

    I will now create a different user, restart and log through the new user.

    I will wait and see if it resolves the issue.


    Will update as I move along.

    Thanks for the help!

  • Ivan Clarke1 Level 2 Level 2

    Okay so we know it is none of the login items.


    try the user profile - let me know what happens.


    next step will be pram and smc reset.

    When you say you're having crashes, what specifically do you mean?  Are you having kernel panics (where a screen tells you in multiple languages that you have to restart)?  If so, the kernel panic log can help diagnose the problem if you post it here.


    Also, see Understanding upgrade nightmares for some possible causes and fixes.

  • Ivan Clarke1 Level 2 Level 2

    Okay Thomas I see what you are doing now!


    good post though....

  • popole77 Level 1 Level 1

    I guess that I'm having kernel panics.

    cause i'm getting this screen you've mentioned.

    Is there a different way to approcach this, then to change user?

    As it's a time consuming task to change everything for a new user, only to discover that it didn't solve the issue.


    What are you suggesting?

    Thanks for all the help!

  • Ivan Clarke1 Level 2 Level 2

    oh no you dont have to change user you could just set up a new user account to test if it crashes.


    Thomas has been around a while and may be able to advise on Kernal Crashes better than I

  • Ivan Clarke1 Level 2 Level 2

    do you have any external hardware plugged in to the mac? if so what?

  • popole77 Level 1 Level 1


    There is no external hardware connected.

  • thomas_r. Level 7 Level 7

    Kernel panics are generally caused by a badly corrupt system, bad third-party software or a hardware issue.  If you're having kernel panics right after an upgrade, and the machine was functioning fine beforehand, hardware is unlikely (though not impossible).


    If you post the kernel panic log, it will contain information that can help identify what third-party software you have installed that may be involved.  If third-party software ends up not being the cause, reinstalling the system might help, but we'll cross that bridge when we come to it.
