I have a iMac G3. I can't make it boot from the CD to install the OS. Keep pressing the C key, but no luck. How can I edit it in open firmware to make it boot from the CD? Or, is there another option to install the OS from a different Mac? I have Mac OS X installed on a PC.
View 1 RepliesSo, I'm still having trouble with the MacBook I posted about here. It kernel panics even more frequently now, a month later, about once every 30 minutes. I'm running 10.5.8 now (no Snow Leopard for me!).
Anyway, the problem I'm posting about is that I can't boot into Open Firmware. It works fine just booting straight through to OS X (except about a third of the time I start up it kernel panics right after the Apple logo appears) but it won't boot into Open Firmware. I hold down Command-Option-O-F to no avail and it just won't go. (I'm trying to do reset-all to see if that helps any.)
I tried booting into Open Firmware successfully on my other Mac so it's nothing I'm doing, this MacBook obviously has some serious issues.
I'd rather not have to take this computer to the Apple Store again - every time I do they just reinstall the system/replace the hard drive and don't take me seriously when I say the problem is not with software. (Plus the warranty on this machine is up now and I'm trying to avoid paying hundreds of dollars!)
Anyone know what the issue could be? i really need a new computer hahaha...
Oh! I also tried booting into Open Firmware by holding down the power button continuously as suggested here... the on/off light blinked 3-4 times, the computer made a really long beep (like I was trying to do a firmware update), then started as normally. So I don't think that worked either lol.
I have a dual 1.8 PPC G5 power mac that I bought used about a year ago. It came with OS 10.5 preloaded but the only discs I have for it are the original system disks(10.3). I've got it hooked up to a HP 19 LCD via DVI. The other day I tried to boot into open firmware using the command-option-O-F start up command. Well, something happened cause OS X never came up, but nothing else did either. The screen just stayed blank, the fans starting ramping up and just got gradually louder and louder. I tried entering mac-boot via the keyboard thinking that maybe I was in OF even though I couldn't see anything on screen, but nothing changed.

Can someone else please use a watch and post your times?
BEFORE the 1.1 firmware update
10 seconds from power button to apple logo - 17 more seconds to load to my desktop = 27 seconds
After 1.1 update
45 seconds from power button to apple logo - 15 more to load my desktop = 60 seconds
I just used a stopwatch 2 times - same results....
UPDATE: tried SMC Reset - same result.
My MacBook Pro (Late 2011) which is fully up to date, no longer boots up. The last thing I did was set a firmware password via Lion Recovery mode. After setting the password, I restarted the MacBook Pro, logged in, unbound the Mac from AD and OD, gave it a different computer name and chanegd the IP settings to DHCP. I shutdown the MacBook, plugged in a Firewire cable and turned it back on whilst holding down "T" to boot into Target Disk Mode.
The screen turned on for a second then suddenly turned off and the light on the front of the MacBook slowly pulses as if its in sleep mode. I've restarted the MacBook several times, with and without holding down any buttons and now it will not boot up properly. When you turn the MacBook on, you can hear the CDROM Drive/HDD moving - like it usually does but with no feedback on the screen. After the normal sounds have stopped the light on the front of the MacBook pulses as if its in sleep mode.

I've just set up an Open Firmware Password for the first time. My understanding is that this would prevent booting the Mac from another volume (i.e. an OS X install DVD). After setting up the password and rebooting my machine, I decided to test things out by inserting my OS X install DVD and selecting it from the "Startup Disk" preference pane. Lo and behold, it rebooted from the DVD without asking for the password.

"Boot Camp Assistant cannot be used: You must update your computer's boot ROM firmware before using this setup assistant"."
That's the dreaded message I get every time I try to use boot camp 1.2. Unfortunately my firmware is already updated, and any attempt at updating my firmware (again) results in the message that I "don't have to update my firmware."
I've google'd this problem numerous times, but I have yet to find a solution.
I have a late 2008 alumunium Macbook 2.4GHz, upgraded to 4GB RAM, running Snow Leopard 10.6.2. Due to a kernel panic earlier today I went through the websites shown in this thread: [URL]. As I was doing some of the procedures, I came across a website about EFI and SMC firmware updates for Intel-based Macs shown below: [URL].
According to that website the Boot ROM Version on my late 2008 Aluminium Macbook, should be
MB52.008E.B05.
Instead it is
MB51.007D.B03
If I understand correctly, the support website probably has a typo, because my Macbook is coded Macbook 5,1 and not 5,2. Also on this website: [URL] it says MacBook5,1 will update to MB51.007D.003, which is still not the number I have in the System Profiler. Of course the above website has Mac OS X 10.5.7 as a requirement, so I'm not sure if the number changes in Snow Leopard. I just want to know if the Boot ROM Version in my System Profiler is ok, or if something is wrong.

View 7 Replies View RelatedI have a strange boot issue having (tried) to install EFI 2.7 update. When I restart the laptop, it 'chimes', displays a grey screen, then chimes, displays a grey screen, forever. I hit the bower (off) button for 5 secs or thereabouts, and restart, same thing. I do this 4 times and finally it reboots. But the EFI update still appears as needing to be installed (software update tells me it is not installed). Update history shows however that it IS installed. I can go through this process any number of times. I now have Software Update history showing quite a few installs opf the EFI 2.7 update. If I just do a restart without installing, I also go through the same fail to restart / fail to start / ... / eventually restart sequence.
So it seems now that the laptop will only start after 4 failed restarts and finally it starts. After starting it all appears to be perfectly fine. Nothing strange in the console logs that I can see. The failed reboots don't seem to register in the console logs - I suspect that the failure to restart is pretty early on in the boot sequence, well before it tries to load any semblance of the OSX kernel. It is almost as if it is trying to boot from someplace other than the disk ... until eventually it gives up and tries the disk. (I have tried booting with and without network cable - no difference) I don't know enough about mac bootup sequences to know if there is some config/setting that is screwed up causing this odd behaviour.

I have the Open Firmware Password enabled, which prevents my machine from booting into Safe Mode when I hold the shift key at startup (as expected). As a result, if I want to use Safe Mode I have to boot up from my install DVD, disable the password and then reboot. Very time consuming! I just read about a way to boot into Safe Mode:
(at [URL="http://support.apple.com/kb/ht1455"]Apple Support[/URL)]
by entering the following terminal command: sudo nvram boot-args="-x"
I'm a little hesitant to test it out in case I run into some sort of Open Firmware/Safe Mode conflict.

typing 'mac-boot' gets me to a white screen with black lines all down it. It just hangs there.
I tried zapping the PRAM but it didn't help. The hard drive has been making those *click click* 'I'm about to die' sounds for a while. I'm assuming its the hard disk . I have another iBook with a failed logic board I can take the HD out of but in case its not I don't want to take it apart just yet.
My open firmware password wont reset.
I tried the method of removing some ram and yes i did it correctly plenty of times and got nothing.
then i also opened the whole intire computer and disconnected the battery and also got nothing.
also right now the system has no O/S so i am not sure what to do from here. I cant use any boot commands or anything.
I have a PowerBook G4 17" 1.33 GHZ machine running OSX 10.5.5 that's booting either with a black screen or into open firmware. Any idea how I can reflash the firmware and if so, where I can download the file?
View 3 Replies View RelatedI just picked up an old eMac today that I'm trying to get it working. The problem is the open firmware password is set, and I have no idea what it is. If the open firmware password is set, it prevents you from doing anything without it including booting from a CD and zapping the PRAM. I changed the ram, removed the internal battery and hit the PMU reset button expecting this to clear the password, but it didn't work. Removing the internal battery did reset the system clock to 1/1/1904, but didn't change anything else.
Also aside from the practical question about resetting the password, I'm suddenly left wondering where the system stores the open firmware password. If it isn't stored on the hard drive, and it doesn't depend on the internal battery, then how is it saved? Just for clarification I have no idea who the original owner was or where it came from. So there is no chance of just finding the correct password.
can somebody make a boot cd dos and include a firmware (192kb) for flashing i would send ?!

I have a mechanical fault with my combo drive (cdrw/dvd) in my Powerbook 12" 1.5 GHz running Leopard which makes it noisy even when there is no disk in there. Is it possible to disable the device by removing it from the device tree in Open Firmware before OS X boots? It sounds like the drive is checking for a disk. I am sure there is not a disk in there as it still accepts and ejects other disks. If it were to be removed from the device tree would this likely solve the problem, or would the power cable to the drive have to be physically disconnected?
View 4 Replies View RelatedI have an iBook G4 which was working fine. A week ago my little sister used the laptop and now I have the following problem:
a) The laptop boots because I get the boot chime, but the screen keeps black.
b) I connected an external monitor to check if the problem was the laptop monitor. When I start the computer, I get a gray screen (in the external monitor), but no apple icon () and cannot pass from this gray screen.
c) I noticed that the caps lock light was not turning on, so I accessed the open firmware (keeping hold the power button - getting a weird chime and a light flashing near the case button - power chime ) and I got the open firmware screen (still in the external monitor) and I noticed that the keyboard was not working also! I connected an external keyboard (usb) and I am able to type.
I know I won't be able to use it as a normal computer because of this weird problem. I was thinking to keep it as a "desktop" with the external monitor and the external keyboard. My questions in this case are:
a) Is it there any way I can boot from cd from open firmware? (I cannot do the "keep the 'C' key hold during start up" because my laptop keyboard does not work.
b) Because I get the open firmware console, could this be a OS problem? What I mean is that if I reinstall the OS, could I at least keep using this computer as a desktop?

View 3 Replies View RelatedI had some problems regarding my Hard Disk in a previous topic, I managed to fix the errors and format the drive. The disc seems ok but there is no OS on it.
And when I boot (in verbose or single user mode) it keeps freezing on:

Now this makes sense to me since the drive is empty but when I enter my Installation disc press ALT or C while booting it just freezes and does nothing.
I see the CD next to my hard drive and nothing happens, anybody had this problem before? What should I do, it's just a 5 months old iMac from the latest generation :/.
My iMac (2.4GHz Intel Core 2 Duo with 4 GB of Ram; 320 GB hard drive with 160 GB available) running OS 10.6.8 takes almost 10 minutes to boot up. Even opening a file folder can take almost a minute. I reset the PRam last week and that helped but now back to slow. I checked the Activity Monitor and I've got over 3 GB of ram free. Could my hard drive be dying? I have dual backup (external hard drive and Carbonite), so I'm not concerned about losing anything, but need this computer to work like it used too.

I own a new-generation MacBook Pro, and I'm a computer gamer. While there are some really good games out for the Mac OS (Enemy Engaged, anything by Blizzard), Windows is still where most computer gaming is centered. I don't want to drop $200+ on Windows just to play games (because that's all I'd use it for). So my question is: Is there any free, legal (i.e., open-source) option which can run in boot camp that will reliably play Windows games? I don't care how crude or sophisticated the user interface is, so long as Windows programs (especially IL-2 Sturmovik) run on it and it's free.
