    Title says it all. Tried updating to public beta 4 through the App Store and the progress bar disappeared and was replaced by the image below. Should I wait it out or should I restart my computer? Or will I have to restore everything from a backup?

    I had the exact same thing yesterday and I fixed it by deleting/uninstalling Vbox in safe mode. Thanks Teddat!

    It happened while it was installing. Now it won't let me startup or enter recovery mode. Running a diagnostic test now. I would make a bootable USB but I don't have a functional computer to do that on.

    Just restart while holding down the shift key and it will boot into safe mode. From there you can uninstall Vbox and restart normal...I had the exact same thing and it got fixed...

    It won't let me enter safe mode. I tried but the loading bar filled halfway, and now it won't move.

    Thank you very much, it appears to be working now. I'm not updating anything until the final version is released.

    Hey, so I appear to have the same problem with my 2011 MacBook Pro.

    Silly question, how do I go about uninstalling virtual box? What is it?!

    Looks like my MBP has the same problem - after finding this thread I'm trying to start in safe mode but I have been looking at a black screen for 5 minutes now after the progress bar disappeared.

    Also if/when I manage to startup in safe mode - how do I remove that Virtual Box stuff?

    The (my) panic screen mentions something about org.virtualbox.kext.vboxdrv like in the screenshot in the original post.

    I had same issue with both a 27 iMac Mid 2011 and a MacBook Air 13 Early 2014. Both machines had a VirtualBox folder which I have now removed. I also updated to Beta my MacMini Server Mid2011 but looking at it now it does not have any VirtualBox folders. Going to try now to update again.

    Update got the same error. Posted this bug to Apple site. CleanMyMac did not find a VirtualBox application to uninstall. Any other suggested would be greatly appreciated.

    I fixed it by booting into safe mode then downloading an older build of Virtualbox: https://www.virtualbox.org/wiki/Download_Old_Builds_4_3
    When you open the disk, there is an uninstaller tool in the lower right corner of the box that opens. To run that tool, you may have to change your security settings to allow downloads from anywhere temporarily. Once you run the VirtualBox uninstaller you can proceed with the update. This worked for both PB4 as well as DP6. Thanks for all.

    I had to reset NVRAM with Command Option P + R before being able to boot in to safe mode

    Then I removed all .kext files related to vbox in /System/Library/Extensions , /Library/Extensions and deleted content from the /caches directory

    After this everything worked normally

    Thanks all
