    I am having this issue on my iMac Desktop after software update for OS X YOSEMITE (2015)

    My desktop starts to boot up, the Apple icon spears on the grey screen with the load /progress bar and it stops just before 50%.

    I have tried disc utility repair/permissions repair - no avail, I tried reinstalling OSX Under here as well, I have booted and rebooted in safe mode nothing-

    I am SO frustrated!!! Can anyone help me?

    And yes I tried disconnecting external plug ins, even unplugging both end of the power chord

    Thank you!!!!

    Hi,

    if you were upgrading to Yosemite 10.10.3, I think you did not wait long enough : it actually takes a very long time with the progress bar stopped just before 50% before the actual install starts.

    Try this: just wait (several minutes).

    Uh what? :confused:

    Also, it really does take a while to update. Be patient.

    Mystery

    After having to power down and hard restart a couple of times, rebooting in safe mode, changing the start up disk to the other internal drive in my Mini Server, changing back, rebooting in recovery mode, then just giving up and restarting, it booted just fine. There's your process. (Seriously, the upgrade just never finished, after several hours, or at least it appeared to never finish. But everything looks like it's working fine now.) (Don't ask me why.)

    I occasionally have the same problem, and I've found that holding down the option key on startup, then selecting the startup drive you want, seems to solve the problem. I suspect this will also work even if you have one bootable partition on your drive.
