I use a macbookpro and an old user has given me his old IMac G3..trying to get it up and running for a friend who has not got a computer. I have started it up and it is running OS 9. I want to put Tiger on it as i have the install disk. Unfortunately when i tried to eject the disk it says that:


'The startup disk cannot be removed from the desktop ,because it contains the active system software'.


In the special menu the eject apple E menu choice is also greyed out.


I checked the support site on Apple for old G3's but it suggests there is a eject button..this imac came from 2000 and has no such button.


Also i have seen the option 'Erase disk' in the special menu. I wonder if I erased that then installed my Tiger disk whether that would work and then let me eject the startup disk too.

    That's referring to the hard disk, not the disk in the DVD drive(if any). If there's a CD or DVD icon on the desktop, drag that to the Trash. If not, insert the Mac OS X 10.4 DVD.

    If the G3 has a CD tray, it won't read a DVD at all, and the highest OS it can run is 10.3.9 (Panther). To open the tray when empty, push it in slightly with a finger and it should pop open so can pull it out to put the CD in.


    If it's a slot loader, you don't open it, you just feed the CD or DVD into the slot and it will be 'eaten' by the drive.

    In either case, to remove it

    a) press the ⏏ button on the keyboard (top right)


    b) Drag the disc icon on the desktop to the Trash - the Trash will turn into the eject symbol (⏏)


    c) press ⌘ and E together


    d) ctrl-click on the disc icon and choose 'eject' from the menu


    If it's a slot loader, 350MHz or slower processer can only run Panther, 400MHz or faster can run Tiger 10.4.11 and they should have a DVD ROM drive at least.

    Choose Restart from the Special menu and press the mouse button immediately after hearing the chime. If that doesn't work, press the Option, Command, O, and F keys, and run the following:


    eject cd

    This sounds like there's no operating system on the HD or the HD is damaged in some way, causing the computer to boot from the disc.

    To see if that's the case, open Disk First Aid and see what's listed.


    Ref loading Tiger - you need to make sure the iMac has had firmware update 4.1.9 applied, and that can only be done from OS 9.1 or above (not OS X).


    If the HD is shown in the Disk First Aid window, there should be a Macintosh HD volume listed. If there isn't, then you'll need to use DFA to partition the HD and format it. (I think that model uses HFS+, but some early ones used HFS, so I'm not sure without further checking - but if HFS+ is an option, it's the one you should use).


    You'll then need to run the installer from that disc before you can restart and eject it.

    You can download a ,pdf manual from here


    If you don't have an eject key, you may not have the original keyboard -

    I think if you erase the disk it might eject it. But I think you will no longer be able to download Tiger on a Mac so becarefull

    In DFA, the volumes listed are: Internal RAM disk and the iMac Install CD,ATAPI DVD-ROM,bus 2,(write Protected)


    That sounds ominous - no entry for a "13GB WD WDX etc.…" or something similar (not necessarily WD, but a HD manufacturer"s name or abbreviation)?


    If that line's not present, you may not have a Hard Drive fitted at all.
