    Hey Fellas,

    I've wasted several days trying to ameliorate this problem but to no avail. Hopefully there's a knight in shining mac aluminum that can present a solution.

    I attempted to install the Beta 6 update as anyone else would but the install froze midway. So I booted into recovery and attempted the same reinstall. Result: same problem.

    Shortly thereafter, I made an El Capitan Beta 1 Boot Disk and attempted to install it over this incomplete El Capitan Beta 6 system. Result: Kernel Panic (I've attached a photo of the screen).

    I've done some research online and it seems that virtualbox and syncmate (among other 3rd party extensions) are the root causes of this kernel fault. I have syncmate installed somewhere on the OS.

    Now I can access internet recovery mode but all the other methods of startup don't seem to work. I also can't access my "Macintosh HD" using terminal in recovery mode to try and delete these culprit "kext" files or whatever else needs to be done on the hard-drive. I would be most grateful to anyone that can offer a solution.

    I have a not so good but possible solution.

    Install Mac OS X on external disk, and boot from there, to see if your old Mac disk is visible.

    So to clarify - are you still on beta 5?

    Try the terminal command: sudo softwareupdate -i -a

    This will attempt the update using terminal which may rectify your issue. Apart from this I am unsure as to what else I can offer.

    Good luck my friend!

    The problem is the following driver


    Looks to be some kind of usb wifi driver?

    Boot into safe mode and remove it.

    Thanks for all the suggestions guys. I tried valiantly, keeping all your suggestions in mind. I even went ahead and created an Ubuntu USB Boot Disk and tried accessing the file system on the Macintosh HD. Unfortunately this yielded limited results and I made the decisionto ditch this recovery effort and just use a 3 month old Time Machine backup to write over the entire hard drive. Live and learn I guess!
