    Some weeks ago I entered Single User mode and then entered a string of characters suggested by MacFixit as a routine maintenance item. I can't recall what it was and should have made a note of it.

    Now, for some reason, I'm unable to enter Single User mode. Holding down cmd-S isn't working (I get the usual start-up instead). My thoughts are that the MacFixit entry that I made must have scrambled something, or I simply screwed up. I want to be able to enter Single User mode and cannot. Is there a way I can do this, perhaps using Terminal App? Can I somehow reset everything back to the default settings?

    Thanks for the help,

    Bill

    What sort of Mac do you have? Can you boot from an OSX disc?

    If you have a boot password setup you can't enter single-user mode, you'll need to disable that before you try it. If you're unsure whether or not you have a boot password, just hold down the Option key when booting to go into Target Disk Mode and if you have a password set, it'll ask you for it.

    Technically booting whist holding OPTION gives you a list of bootable devices, whereas booting holding T gets you into Target Disk Mode. :eek:
