    Im having a few problems with my mac at the moment (g4 1.44 minimac)

    Its just crashed again! and this time i cant fix it.

    Before when ive held alt on start up ive come to a screen from which i can relaunch osx (10.4). this thim there are only two buttons: the curley arrow and the right poniting arrow (which does nothing!).

    Ive called apple before (very very expensive) and they told me numerous key commands to try when starting up...but ive forgotten then now!

    I would be eternally greatful if someone could help me out, it so important i get this working tonight to meet a deadline for my work tomorrow.

    Thanks guys any suggestions would be great!:eek:

    OK, but you should try to be a little more informative from now on :).

    Shift at startup puts you into safe mode.

    Shift at login disables login items.

    Command + S boots you into Unix (Single user mode.)

    Command + V boots you into Verbose mode, which I don't understand the use of.

    Command + Option + P + R resets parameter RAM

    Command + Option + O + F boots into Open Firmware

    The last two are (as far as I know) only for PowerPC Macs.

    Good luck!
