    I have a 2013 iMac with a 3 TB Fusion Drive. On instal, the bar said 29 minutes, then the countdown disappeared & the bar got to about 95% of its length, then has stuck there for more than an hour now.
    I had two USB hubs, a second monitor (Cinema Display), and an exterior Time Machine Hard Drive plugged in, but all are now disconnected. What to do next?

    I'm in the same boat. I'm screwed. I made a time machine backup right before doing the update. Somehow my external drive is now bad and can't be read or repaired so I can't restore. I've rebooted into recovery mode and tried restarting the installation but that just puts me back in the same spot. Stuck.

    Ouch! I hope someone can give us both help here!
    I tried CMD + R but the iMac just booted back to the same screen/progress. No offer to go into recovery mode. My keyboard is the wireless one the iMac came with; could that be the problem why I cannot even get to recovery mode?

    Exactly where mine "froze" but even the countdown was not showing! What Machine and Hard Drive are you on?

    Before you try the install again, try resetting the PRAM, prior to the install. Hopefully that should help clear out any corrupt install files and permit a complete install.

    I have the same problem on my MBP 2011 model. I've decided to use time machine and restore to my last update I did last week. I will download a clean copy on an 8gb sub stick and try that method. All this wastes so much time!

    I switched off the iMac, waited a few moments, & then restarted while holding down Cmd + R
    First two times it went to the same screen & stayed there
    Third attempt, the same screen, but after two minutes the restore screen came up. I am now restoring from a Time Machine save from Yesterday - not worth the risk to try again, I will probably wait until the first update is available before trying again

    Always a good idea to make a usb installer for time like this

    -dl el capitan
    -don't upgrade,close the update app
    -plugin min 8gb usb stick
    -open disk utility,and partition stick as followed...OS Extend (journaled),GUID partition table
    -open Terminal command
    -paste this command (without the ") "sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction"
    -wait 20 min or so

    to use plugin usb stick and hold down "alt" option key at boot and pick el capitan...will take a while...open disk utility and
    partition internal drive as OS Extend (journaled),GUID partition table...close disk utility and pick install osx...wait 2-30 min and done!

    Cool! unfortunately this did not work for me, thus the roll back (2hrs 38 minutes to go... :))
    First time I had an upgrade problem, & I was especially hopeful as this iMac is relatively new, cycle-wise, was a refurb from Apple purchased just a couple of months ago etc.
