        Hi all,


        I'm sure there have been several discussions already around the forums, but just checking in to see if anyone else has experienced my issue as below:

         

        • After download complete, auto-restart but progress bar at Apple Logo screen stops at 75%. Even after a hard restart, starts up stuck at 75%....
        • Reset PRAM, entered Recovery Mode and restored from Time Machine to last state before the issue occured and everything was fine, 4 days later...
        • Woke up in the morning and found computer had restarted itself (suspect it decided to auto-update) and progress bar stuck again on 75%.... Exact same issues. Repeated restoration process and now working fine.

         

        I'm just a bit nervous that this is going to happen again... I've been reading around the forums about manually installing the FirmewareUpdate.pkg as well as deleting the iCloud / Accounts folder. I have deleted the iCloud Accounts folder, but holding off on manually running FirmwareUpdate.pkg.

         

        Has anyone else experienced this as well? Or does anyone have any suggestions to avoid waking up to another bout of Macbook Zombie-itis?

         

        My Macbook is:

        MBP Retina 13 (mid-2014 model)

        2.6 i5

        8GB RAM

        Intel Iris

         

        Thanks all!!

          El Capitan Beta 4

           

          I have exactly the same problem. Also MacMini 2010 Intel. The 'progess bar' stuck forever at

          about 70%.After several restarts and all sorts of attempts, The progress bar shows 100%,

          but in fact there is no progress.

          Starting with cmd-s tells me debugger panic, no OS installed yet etc. It is impossible to type

          into the command line.

          Rebooting with option key down allows me to choose Network Install and recognises the router

          but refuses to accept the router password after many tries.

          Absolutely no idea what to do next.

            Hi Jonotan,

             

            It's likely that, as you suspect, you do have auto-update on. Go to System Preferences > App Store and un-tick "Install system data files and security updates" and "Install OS X Updates" (if it isn't greyed out)

             

            There are some kexts left over from old installs of VirtualBox and Eltima SyncMate that have been causing this issue for others. The following will remove them (if they're there) and also serve as a test to see if this was indeed the issue for you.

             

            Open a Terminal window (press cmd+space and type "terminal") and copy-paste the following commands, one at a time, into it. The first one will ask you for your password but it won't show as you type it in - just press enter afterwards. Please then copy-paste the output of the commands to your reply to this post:

             

            • sudo rm -Rf /Library/Extensions/VBox*
            • sudo rm -Rf /Library/Application\ Support/VirtualBox/VBox*
            • sudo rm -Rf /System/Library/Extensions/Eltima*

             

            If just one of the 3 commands above doesn't return a "not found" error, then there's a good chance that you can then update to Beta 4 without issue.

             

            Max.

                Hey Max108,

                 

                Thanks for that!


                Here is the Terminal reply:

                Password:

                JTs-MacBook-Pro:~ Jono$ sudo rm -Rf /Library/Extensions/VBox*

                JTs-MacBook-Pro:~ Jono$ sudo rm -Rf /Library/Application\ Support/VirtualBox/VBox*

                JTs-MacBook-Pro:~ Jono$

                 

                I haven't used Terminal for a long time, I don't remember if its meant to return a confirmation that the file has been deleted proper.


                Thoughts? Suggestions?

                 

                Would like to update to Beta 4 but just holding out so I don't end up with a frozen screen again!!

                    I just tried it myself and the f option is suppressing the error output (in the case of the files not being there in the first place) making it useless as a diagnostic - my bad .

                     

                    We'll have to check if the commands deleted any files by running the following commands and looking at the modified date:

                    • stat -x /Library/Extensions
                    • stat -x /Library/Application\ Support/VirtualBox
                    • stat -x  /System/Library/Extensions

                     

                    If the "modify" timestamp of any of those outputs corresponds to when you ran the sudo rm commands then you can be confident that you did delete the probable culprits.

                     

                    Check for yourself or post the output here if you want me to check.

                        However, I've just noted something strangely wrong - my internet has experienced an increased slow down over the last few hours since I ran those commands.

                         

                        Any possibility those are related? Or do you think its just a bad internet connection....?

                            Hi

                             

                            No the internet slowdown isn't related. The commands you ran did not delete anything (I can tell because the timestamp of Tue Aug 11 04:04:12 moments before you ran them is after the modification timestamp of the folders the files would have been in - Tue Aug 11 04:02:52 2015)

                             

                            What that means is that your Beta 4 install failiure was not caused by the most likely issue of having VirtualBox or SyncMate installed because there's no trace of their kexts on your system.

                             

                            Therefore I suggest you hold off on updating until we see what the next Beta is - combo or delta.
