Q: El Capitan hangs at reboot

I have searched through the forum and on other websites as well but have not found any help.  Have tried the following without any success:  restarted my computer, restarted in recovery mode (Cmd + R) and opened up disk utility and ran first aid (none of my disks are damaged); reinstalled El Capitan.  I give up - have tried for two days now to fix my computer without any luck.

 

What else can I do?  When I start my computer after installing El Capitan it gets to the loading bar and just stops.  Will I lose data if I reinstall Yosemite on it again?

iMac (27-inch Mid 2011), OS X El Capitan (10.11)

    I had similar problem, to get out of the issue i simply used Time machine and went back 2 days to before i loaded ElCapitain. I then found a thread about a similar problem where the loading bar sticks at 90% when ElCaptain has been loaded and there is a very detailed explanation of what to do to fix this problem. I therefore followed this step by step cleaning out all the old caches etc takes about 15 minutes to do this. I then did a reboot. to get a clean start and checked everything was working okay. I then forced a new Time Machine back up. I then downloaded ElCaptain again. Did the reboot at the end of the install now Problem sorted.

    Have a similar problem. Macbook pro hangs at apple logo after reboot with el capitan.... here's part of my etrecheck 2.5.5 output

    I got plenty of free RAM, so can't be the cause.

     

    System Launch Daemons: (What does this mean?)

        [failed]    com.apple.Kerberos.digest-service.plist

        [failed]    com.apple.csrutil.report.plist

     

    Virtual Memory Information: (What does this mean?)

        5.56 GB    Free RAM

        10.00 GB    Used RAM (6.48 GB Cached)

        0 B    Swap Used

    Same problem, same iMac. Trying to re-install but the app store is down. Not sure about the data question, but given the mess at the moment I wouldn't re-install Yosemite over the top, unless from Time Machine. What an update.

     

    EDIT - Just read elsewhere you can't reinstall Yosemite again without wiping the disk first, so Time Machine would be the way?

    You need to post the entire etrecheck report back in your own thread. This is someone else thread and posting here will only confuse their issue.

     

    Cheers

    You need to post the entire report as snippets do not allow us to look at your system and try to diagnose.
