    Not sure where to post this.

    Hello All-

    I'm trying to do some cleanup and maintenance before upgrading to El Capitan. I have followed this thread up to "fsck": http://forums.macrumors.com/threads/guide-zap-pram-repair-permissions-run-fsck.89736/

    I follow the directive (on fsck) but I do not get into "single user mode", the iMac just restarts as normal. It has worked in the past for me on this machine, but not now?

    Appreciate any comments. It worries me to try to update to El Capitan when things are amiss, I have plenty of other problems to worry about with legacy (older) peripherals and apps.

    TIA

    On a recent machine/os, you should be able to boot into the Recovery partition (with CMD-R) and run Disk Utility/First Aid on your OS partition.

    I know we all have our upgrade 'voodoo' but I have to say that all I do these days is unmount/unplug my externals, reboot, and upgrade.

    Best of luck,

    Thanks for the reply Alrescha, when you say unplug "externals" do you mean printers/scanners etc.?

    No, I do not usually bother with that. I just unmount and disconnect my external drives.

    command-s at start should get you to single user mode still. Try a complete power down then hold command-s right after you hit the power button.

    That did it! A complete power done, not a restart. Thanks Weaselboy!
