    Hi Guys,

    Following the new software update, my iMac refuses to sleep, either by pressing the power button or manually selecting sleep. It turns off, then the CD tray tries to eject a non-existent CD and the machine starts up again.

    Oddly enough it seems to sleep absolutely fine after a shut down but as soon as I open and then close apps (mail, firefox3, itunes) it repeats this weird bug.

    Is there anything I can do to solve this? It's been fine up until I installed successive versions of Leopard

    Ok interesting things I have found:

    Zapped PRAM (did nothing)
    Ran disk first aid (safe mode, from leopard disc and Mac HD) - turns out there's a bucketload of permissions that don't get fixed no matter what I do.
    Turned off SMC Fan Controller

    None of the above worked.

    HOWEVER!!!

    I had heard that Apple iMacs boot on USB signal, so I pulled all the plugs out and it slept fine. I narrowed it down to a third party USB mouse that I like using (hate the mouse nub) which was stopping it from sleeping as it was constantly powered on.

    Lesson learned - Apple OSX is very finnicky with USB devices sending signals even in sleep mode.

    I guess my next question is to find out what third party mice don't interfere with sleep mode.

    Razor Deathadder, good stuff thanks for the suggestion!

    I guess I'll have to shell out a bit more for a good quality mouse this time round if I want to avoid problems. Now what happened to that Logitech G5 wired mouse, I wonder if they still sell it :D - I prefer a proper mouse (ie: clearly defined buttons!) for gaming (TF2 and Stalker through Bootcamp and sometimes OpenArena in OSX) because the mighty mouse is more of a limp squid when if comes to fragging.

    In case you're wondering the mouse I have had to replace was a mongrel brand / strange mouse I bought in Germany (I was a British student studying/teaching English at the time) that comes from a brand called "Manhattan". I can't recommend them if it causes a problem like this.
