    Hi everyone,

    I have a Mac Mini G4, which I use for MorphOS. Sadly it has stopped working. Whenever I try to power up the computer, it shows a blank, grey screen. Have tried various key combinations during startup to boot from CD (MorphOS live CD), access Open Firmware, but none works anymore. Did also change the RAM, tried DVI-VGA adapter and regular DVI cable, switched monitors, but still the same issue.

    So, the question, is there anything else one can try to get it up and running or is it best looking for a replacement?

    Thanks in advance. :-)

    Make sure you’re using an Apple kb to try and access OF/other key combos. Some kbs may not trigger this correctly.

    Try to erase nvram with cmd+alt+n+v. Afair keeping those keys pressed as you press and hold power button with 3rd hand can help too. Do this while it’s powered off initially.

    Many thanks, Jacadcaps! :-) I will ask someone to help me with this. Hopefully I'll get it up and running again.

    @ Puni - I also thought it could be a dying/corrupted HDD, that gets to the boot process but fails on the initial screen, and with an "alien" keyboard maybe the "alt" or "C" presses aren't recognised so it remains in a state that won't boot, but if you've got an Apple keyboard plugged in then this may well not be relevant . . . it's just a thought that . . . might be relevant. ;-)

    Hi NewSense,

    Thanks for the info. :-) I don't have an original Apple keyboard, unfortunately. If this could solve the problem, I could try finding an old one for sale or lend it from someone. Could it help trying different "PC" keyboards too? Thanks again. :-)

    Try it! I have on both Minis (and G5) normal USB-PC-keyboards, which works fine (can reach OF-console).

    Got hold of an older Apple USB keyboard here, which looks like it could be from an old Power Mac of some kind. Waiting for it to arrive in the mail. :-) Hopefully this will sort it out, or else I'll have to get a "new" MorphOS computer.

    @ Puni - If this is of any use to you . . .

    I use an Apple A1016 Bluetooth wireless keyboard with my MacMini G4 - which requires setting up through Mac OSX as the Bluetooth options/pairing are required to be set up on MacOSX (Dual Boot MorphOS/MacOSX - Tiger 10.4.x is more preferable to me). 8-)

    You can download Tiger 10.4.x from Wayback-Machine / Web-Archive - $ Search = Mac Tiger as either CD ISOs or a DVD archive along with loads more Mac stuff (if you really want to . . . though I prefer MorphOS) but I really only use it to get the Bluetooth features operational. 8-D

    Humm, for my own experice, the problem can be in the boot selector from MacMini, if the DVD neither works, this internal hardware can be dammage and it hasn't reparing, but always there is hopem and the mechanical hard disk cans dammage because this hardware has almost 20 years old, in this case you can put other hard disk mechanical or SSD, but you first try to start the MacMini from DVD with MacOS or MorphOS CD/DVD, also if you have an ide adapter, remove the hard disk connect it to this IDE adapter and connect all to one Pc or other computer to know if the hard disk is live.
    I write many suggestions but with a windos board you can hold down the C key while the MacMini reboot and with the CD or DVD start the computer, if your computer neither start well, the problem is boot selector hardware from MacMini, that the started with the CD, well the hard disk is dammage.
    I hope hel you.

    Thanks everyone for your help in getting the Mac Mini up and running again. :-) I'm currently waiting for the keyboard to arrive here before I do anything more, but... turns out I was lucky enough to get hold of a PowerBook G4 yesterday! Installed MorphOS on it, so now I'm back in action again, hehe. Will still try to get the Mini working of course, but I think this laptop will see a lot more use in the future. ;-)
