Guys a mate of mine has asked me to look at his iBook G4 as it's having issues booting up.
the machine starts, gets the apple logo and then to the Starting Mac OS X screen, the blue loading bar reaches the end and just hangs (i've left it for 20 mins and nothing).

so far i've tried:
:cmd: + option + O + F. Then typed in: shut-down
no change

:cmd: + option + P + R - for PRAM Reset.
no change either.

wondering if i do this: http://forums.macosxhints.com/archive/index.php/t-30673.html
will it wipe my HD?

no it wont, it moves the current system files to one side,
renames them "old system" (or like) and installs a new OS. takes some space tho, about 2G+ dept on installation (apps, printer drivers, languages etc)

but have you tried in firmware mode
"reset-all" or "init-nvram"

Ray

EDIT: try booting "apple symbol' "v"
give you the non-gui load sequence

could see where you get up to

check the space on the drive. if it's nearly maxed, .. move 1/4 of it's data to another drive, . restart, see if it boots up. if not, then sys files may be too severely damaged & you may need to archive install the computer.

can you hear the disc drive busily working ? if so, may be time for a new hard disc. I ran into this problem with one of my friends' ibook.

Cheers for the prompt reply Ray, i tried the reset-all, no change.
init-nvram says it's not recognised?

any other ideas?

yeah the drive and fan are busy working, i was thinking the HD was shagged too.
he leaves the iBook on all the time, it never gets a reboot.

reckon i'll try this first

and if it still has issues i'll replace the drive.

unless there are other options?

try hardware test with boot CD's?

or for space on HD try disk utility on boot cd

hey Emerson...

because the machine boots, . .. and to a blue screen, .. it simply means it's having a software/startup issue, reading the drive/startup data. i've seen this a thousand times, ... and 8/10 times it's been because the user has over/filed his drive. doing an archive install may not be possible if the drive is too full &(according to my assessment) you should always keep at least 1/4 of your space free at any time.

if you have another mac, you may link via firewire & target disc-boot your system(there has to be a link here somewhere), and check your space, backup some data etc. if you have a boot cd/dvd, start off this & you should be able to view your space by opening the disc utility. take it from there.....

a word of advice, if the drive has just the bare minimum space available, don't install the OS again. you are likely to run into problems that will make fixing/maintaining user data/preferences impossible, resulting in a very messy repair job.

Probably better to boot into target disk mode via Firewire if possible. <Doh, emerson beat me to it>

So you can see the Hard drive on your mac mounted as an external drive and try to fix it that way.


To do this, have both computers in question turned off. hook the firewire cable up to both computers. Boot the computer in question up, hold down T. wait for the firewire symbol to bounce around the screen. Turn yours on, away you go!

Edit: You should try deleting his porn collection, see how much that takes up :P

hmmm just checked free space and he has plenty, 60GB HD and 28GB free.
i i have just tried to repair disk permissions (there were heaps of conflicts) and then repair the disk but that repair failed?
now when i boot up i get weird OS9 type icons prior to the apple logo and it doesn't go to the blue "starting mac OS X" screen.

any more ideas???

Im paranoid about how much space i have left.

Im always deleting things :P

Also you should try running maintenance scripts that clear the logs etc etc.

Mac Janitor does the job quite nicely

ok, .. if your repair failed, you only have one option. try carbon copy the machine, .. then format the drive. you may do a zeros format(look in security options) to verify the drive is ok. next, boot from a a working machine, with the backup on it, .. and carbon copy the user/data back. next boot off the system dvd & archive install the system. this should get you back up and running with minimal fuss

i seems the HD isn't mounted anymore (according to disk utility) assume thats why i dont get the loading mac os X screen anymore?

Mctastic how to i carbon copy the machine?
