I Cant start from system disk

When trying to start from system disc 10.4.8 I get the following error-
panic (cpu0 caller 0x002E54BC):unable to find driver for this platform:"Powermac8,1"
Can anyone help?

Hello again, I have a G5 powerpc iMac that came with 10.3.x and has been updated to 10.4.11. It will not start up, all I get is the white apple screen with spinning progress wheel. The problem is that I can only start off the 10.3 disc and the 10.3 disc utility can not diagnose 10.4.11 properly. Can not get around this problem? (see following link) http://docs.info.apple.com/article.html?artnum=301266. My 10.3 disc utility tells me that I have an 'invalid leaf record count' when I diagnose the volume that has been updated to 10.4.11. Also Tech tool that came with my applecare support plan says the volume check has no errors. Can anyone help?

Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up?

When I started my iMac today, it started beeping like an alarm horn. I shut it down, and held the startup button a little longer to get it to start. Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up? Am I screwed? HELP!!

What you are seeing is a kernel panic, often but not always connected with a hardware or peripheral issue, so, unplug everything except mouse and keyboard, reboot and hold the shift key as soon as your hear the chime, continue holding it until you see the Apple Icon and spinning progress indicator, then post back.
It will take noticeably longer than normal to start.

Com.ms.securityExceptionEx in IE -- started from local disk

Hi,
I use an applet that connects via intranet to a database. I know about all the security issues related to that, but here's the problem:
** it used to work: **
- starting the applet from my local disk, it did work before in the browser (IE, security settings medium or low). starting it from the file/web server, it didn't work due to the security issues ('access denied').
- changing the java.policy settings and using the plug-in and HTMLCOnverter, it obviously did work also when loading from file/web server.
** it doesn't work anymore: **
- days later, it doesn't work anymore without using the plug-in. security settings low, starting from local disk!! The message is:
com.ms.securityExceptionEx[myapplet.mymethod]: cannot access myhost.
I found this error message here in the forum, but often related to sockets or rmi. My applet is as simple as you can imagine and doesn't use any sockets or rmi. It works using appletviewer. Microsoft says sth. like 'an untrusted applet tries to execute a trusted method'. Something messed up with my IE? Is there any java.policy-like file or option for IE?
Thanks for any help

Can't Start from Install disk or external Hard Drive

I've installed an operating system on a external WD 120Gb hard drive. I am unable to start up from the WD Hard Drive or the Snow Leopard install disk, either by selection them from the Startup disk or by pressing 'OPTION' at startup. Every time one of these is selected, the computer starts from the MacBook internal hard Drive.
I have installed the operating system on an Iomega 1 Tb external and it doesn't show up on the Startup disk or when I start using the option key.
I have reinstalled the operating system on both the MacBook Pro Hard drive and he 120Gb portable.
I have a 2Gb SimpleTech Dual Pro Drive, which I can see and start up by, using the Option key at system boot.
I have a 500Gb Iomega I am using for my TIme Machine.
I can't figure why I am unable to start up using the Software DVD.

Thanks for the tip. In the end I combined bits and pieces of what I had read on other peope's messages, what worked for me was putting the frozen computer to sleep with the power button and then waking it up with both the mouse and the C key held down at the same time. Individually nothing happened but with both the CD popped out.
Thanks again,
Jason

Opening the HDrive with Mac booted from System disk? Any help please?

Is it possible to open the HDrive and look/search for files inside it
while my Mac is started from manufacturer's system disk?
(It seems to me I can do just system reinstall and use dusk utilities but have no way to see what is in the HD)
I am a novice and any tip from experienced users is welcome!
My MacBookPro has OSX 10.6

Thanks Kappy for this reply, which is my first glimpse in really hi tech things!
I started with opening Terminal and
following line appeared :
-bash-3.2#
next to it I entered as you told me:
/sbin/mount -uw /
and clicked on return (here I don't know if it is right thing to do ) and got this :
usage: mount [-dfruvw] [-o options] [-t ufs | external_type] special node
mount [-adfruvw] [-t ufs | external_type]
mount [-afruvw] special | node
followed by another new line:
-bash-3.2#
( I tried to to type lines as accurately as possible because I can copy them in Terminal but have nowhere to paste them - the laptop in question works only when booted from CD.)
So, from this point I don't know how to proceed - where to enter the line you recomended: cp /Users/stephanie /Volumes/Backup/stephanie
and what are the exact steps to perform...
Also I don't quite understand what is "Home folder" -is it the administrator account folder which I named when installed the system for first time?
In my computer it is named "steph77"
Also some extra info that may assist you:
My external drive is named "LaCIE" and is plugged in the MacBook.
My internal hard drive to which I want access is named "MacHD" and my account
steph77 is inside it.
Can you help me with the steps to accomplish my task?
It is my first time meeting with command line and am a bit lost but very determined to learn it!
Thanks in advance Kappy , waiting for your reply !

Cannot start from install disk

We have a multi mac household and I'm pretty sure (but not positive) the 10.5.4 install disk belongs to this computer (MacBook Pro). I really need to use Disk Tools but when I try to start with the DVD I grinds for a couple minutes then just sits there with a gray screen (no apple logo). I've tried:
Inserting the disk normally, clicking on install and clicking the restart button as required.
Holding down the "c" while starting
Holding down option while starting
Holding down "d" while starting (for hardware test)
Zapping the PRAM
Changing the startup volume in the settings
..but I always get the same result as above. I have to hold down the power button to get it to shut down, then restart with the trackpad depressed to get the disk out.
Questions:
1) Does anyone have another idea I should try here?
2) Is the gray screen I'm seeing a symptom of trying to start with the wrong system disk?
3) How does one know if the install disk is the right one for the machine?
Many thanks!!!

While the media issues get sorted out, I can offer a workaround to completing the disk repairs, sans Install DVD (BTW, that's why the latter day media came only one to the box; they rolled everything together into a single dual-layer DVD). Normal disk repairs require booting from alternate media because the OS is doing multitasking, that is, accessing the boot media thru various concurrent processes. If multitasking is disabled, the issue disappears.
So, since you're in the Leopard world, I offer two choices. Best would be you download and install the latest release of the AppleJack utility ( http://applejack.sourceforge.net/ ), this is the premier power-user disk repair utility, which we Lion users miss dearly. AJ comes with a quick and easy installer that simplifies the process of getting it ready. Else you will have to do some command-line stuff by hand.
How to proceed; get this down somewhere, cause the Mac won't be usable till you finish. Restart the Mac and hold down the Option Command S keys. This gets you into Single User mode. No graphics interface here and all commands have to be typed on the screen, just like Grampa did back in the dawn of the Computer Age. After the # prompt appears and if you previously installed AppleJack, just type applejack and the return key; follow onscreen instructions, at least do steps 1, 2 & 4. If #1 shows any errors, redo until it comes out clean. When finished, return to quit and restart as indicated by the AppleJack prompt.
If you did not install AppleJack, type the following command exactly as written, followed by the return key: fsck -fy Wait until the # prompt reappears (may take awhile), repeat if any errors are indicated, then type reboot and the return key to restart the Mac. Not as thorough as AppleJack, but this will fix your HDD.
There, you will have now gone deep into the belly of the Unix beast running on your Mac. This is the non-graphics, non-fancy version of Disk Utility, just like computers were done before graphical GUIs.Since only a single process (fsck) runs in Single User mode, it is able to fix the disk without the multitasking issues. Of course, if you can't get a clean and error-free fsck run, the HDD has problems it can't fix (just like it may happen with DU) and you will need more help. BTW, fsck is the Unix geekcode for File System ChecK.

Macbook Pro doesn't start from internal disk. How to?

Hi.
My Macbook doesn't startup. I tried to repair it but it isn't possible and now I need to do one last backup copy before format it. But it doesn't pass from the grey apple screen.
I've checked the S.M.A.R.T. and it is OK. What else can I do to start from the internal disk on last time?
Thanks.
Best regards,
Telmo

Hi. Yes, I did. It goes on and on with the grey apple screen.
I just need it to boot one last time to save one Word document that I didn't had the chance to backup.
The internal disk appears on the disk utility when I star from the install disk and I select it to boot but when restart nothing happens.

HT203176 Unable to boot from System disk to access Disk Utility

Hello
I need want to run Disk utilities on my mac. Have done this before using system disk and holding C etc.
Since upgrading to Snow Leopard from Leopard it no longer sees my system disk.
Restart holding down C with system disk installed...and mac just boots-up normally!
Can anyone suggest what the problem is?
NB: Ultimately I want to run the disk utility to check that the Hard Drive is healthy after install.

Hi chaps
You get the picture....holding down the C key expecting to see the install software option and all I was getting was my desktop. I tried the option key and no joy there either. I was beginning to think it was the two Mac superdrives installed in my mac which are a nightmare. They only seem to be able to read mac disks!!! all a bit incestuous. I found out via the forums that the Sony DVD RW DW-D150A have taken up a lot of airtime. Still pondering what I can do about them...they were fine and the 2nd drive has never really been used. Apparently they are a rebadged NEC burner but they suddenly decided to get choosey about what disks to read....anyway sorry I am losing focus.
Stuck the Snow Leopard disk and instead of restarting or holding C I just clicked on the desktop icon and pressed the install 10.6 button. It huffed and puffed and chugged away turning my screen blue and then grey and finally coming up with a box with two options...install 10.6 or Utilities. Pressed utilities and I was in familiar ground...Disk First Aid!!!! Ran the verifications and repair buttons and a few fixes and job done....a healthy report on the state of my HD.
To be fair the small booklet does say... to install Snow Leopard insert your installation disc and double-click install Mac OSX. I guess I am so used to using previous versions of the OS and pressing C etc hat I did not realise I could access the utilities/First Aid the same way. Took the best part of my day to do this and if they had put in a 3rd paragraph in the booklet to say access Utilites/First Aid the same way my life would have been a whole lot easier.
Now scared to upgrade to Lion as I really am not enjoying the mac experience at the moment....too much depends on my mac and software working without having to worry about technicalities or IT. It’s just not my bag. Thanks guys for the suggestions and your time. I am interested on your opinions with regards to the two superdrives! I have stuff on old DVDs and it just doesn’t see them but it used to...why? My fault for buying two of the buggers I suppose.
Regards
Simon (Mac fan)

ITunes10 does not start from Data-Disk(error 13001)!

After moving my user folder to an external disk I get the message "Could not open Application "iTunes". Unknown error 13001. Reinstalling iTunes did not help, neither did an alias of the iTunes-folder in the equivalent folder on my System-disk.
Any help appreciated!

Found the solution myself. I had a " in the name of the external drive. After removing it all worked fine.

G5 will not boot from system disk or from Tech Tool Pro 5

Hi everyone - Having a bit of trouble and hoped I might find some answers here.
I suspect my system drive was having some issues as it sounded like it was being taxed and strained as I would open up applications from it. Upon verifying the disk using Disk Utilities, the test would stop short with the following message:
First Aid Failed
Disk Utility stopped verifying "Macintosh HD" because the following error was encountered
Filesystem verify or repair failed
In addition, an error message came up (in red) on the disk utility screen as well saying:
Volume header needs minor repair
The volume Macintosh HD needs to be repaired
Error: Filesystem verify or repair failed
Normally from here, I'd start up the computer from the Tech Tool Pro 5 disk (holding down C key upon restart). But when I did this, the computer never responded. Instead, the power was on but the screens went black and the computer went into a very quiet "idle" mode.
After about a minute, the fans began ramping up pretty high (and loud). This went on until I finally had to manually shut down the computer by holding the power switch down for a few seconds. I didn't know what else to do. Those fans were not coming down (not even after 10 minutes).
Anyway, I pushed the power button again and held the C key down. Still, nothing.... The fans stayed idle, for a little while and then ramped up again just like last time. I hit that same dead end and powered down the computer via the power button.
Is there an alternate way to boot the computer from Tech Tool Pro or the original start up disks? I'm having no luck, here.
I'm on my way into town to purchase a new internal drive (something with about 1TB of space) so that my pro apps can swim a little instead of being being bogged down on a 250G drive.
Thanks for any assistance, folks!
Oh yeah.... Happy New Year to everyone!!

The Install disk has version 10.4 on it. I have also tried booting from my OS 10.5 disk but with no avail.
However, here is an update on my plight.
Apple tech says that after hearing the symptoms, he thinks that one of the processors is shot. Being that my particular model of G5 (dual 2.7 processors) is a liquid cooled machine, it's possible that some sort of leak has formed and has either taken out a processor or has caused a processor to overheat. He says that this model of G5 has been known to do that. In this case, nothing will boot which makes me think that my original system drive may actually be okay. I'm taking it in for the tech to look at it and just be sure that's the problem. However, if it is a dead processor, the part alone would run $799 plus labor to install it. Frankly, that's just too much for me to pay to keep this old G5. I'd rather put that money towards a new or reconditioned Mac Pro 8 core or quad core machine.
I've owned several Mac computers in the past and perhaps this is the frustration talking but it seems that no matter how diligent you are in maintaining your Macintosh, these machines only seem to last about 5 years before something majorly wrong happens (mother board, processor, etc). Can I expect this same, limited time frame from a new Mac Pro? I mean, am I just being paranoid?

Starting from external disk: cannot unmount standard startup volume

Hi all,
I started my my mac from an external disk to do some maintainance on my standard startup volume but this volume cannot be ejected.
I already tried lsof to find out whether there is still a process running on the starup volume but lsof doesn't list anything.
what else could be a reason for this problem?

Hi Konstantin;
How did you get the system on to the external drive?
It sounds like there is still something that is dependent on the internal system drive.

Upgrading to Leopard, won't start from Install disk?? Even with 'C' held

Hello, I'm trying to upgrade to Leopard and then Snow Leopard. My DVD drive works, as in I can read DVDs, burn discs etc. When I insert the Leopard upgrade disk (genuine, bought from Apple and already exchanged once) it asks me to restart to get to the Installer - so far so good.
But it just won't get to the Installer stage, I only get the circle wheel, no matter how long I leave it on for. The DVD makes some noise, it is being read but it doesn't boot. I have tried holding the 'C' key and selecting the disk as startup via system preferences, to no avail. I exchanged the disk at the Apple store just in case it was faulty, but I'm still having the same problem.
Is this a hardware problem? Is there any way I could get round it?
Thanks i advance!
Julie

Do you know of a way to 'bypass' the restart to get straight to the Installer?
Do you have a second Mac around? You can "borrow" the optical drive in another Mac by starting it in Firewire Target Disk mode.
There are other ways, but they are pretty involved and require a bootable hard drive you are willing to erase.
And I heard that I'd have to erase my hard drive to upgrade to snow leopard directly, is this right?
No, you do not have to erase the drive.
The only thing I can think it perhaps your optical drive is going bad. I believe that drives have to meet more stringent requirements when called upon to boot from a disc than when just playing a DVD when they can skip minor errors.

How do I reinstall from system disks on my Imac?

I received two disks with my Imac. One is titled Mac OS X Install DVD; the other Applications Install DVD. I managed to get the first disk to boot up and install but not the second. In the first disk was the instruction "To start up from Mac OSX hold down the C key as the computer starts up. One the second disk is says hold down D key. I have made numerous unsuccessful attempts to get the second disk to boot. I assume that the installation of these two disks completes the system installation. I recently changed from a PC to a Mac and am still pretty green with it. Any help would be appreciated.

Reinstalling fonts from system disk

I need to reinstall the Helvetica and Times fonts that came with Tiger 10.4, but I don't want to reinstall the system and go through all the updates. In fact the 10.4.7 installer won't install on top of 10.4.10 anyway. Even if it did, the Custom Install option doesn't let you install just the basic fonts (you can only install additional foreign-language fonts). Is there a way to grab just a couple fonts off the Tiger disk?

Restoring Lost OS X Files
If you erase or otherwise "lose" an OS X system application or utility (such as Mail or Disk Utility, for example) you can restore them without having to reinstall OS X.
Download the shareware utility Pacifist. Read the documentation. Use Pacifist to extract a fresh copy of the missing application from the file archives on your OS X Installer disc. The file archives are usually found on the installer disc in the /System/Installations/ folder.
After restoring the application you need to reinstall the OS X Combo Updater for the version of OS X you currently have installed. This assures the new copy of the application is updated to the current version.
Lastly, it's a good idea to repair permissions.

Can't start from leopard disk to do restore

So if you need to do a "restore all" you need to boot from your system dvd, right? And I've done it in the past. But since the last big system upgrade I can't get the system dvd to boot - just that darned loop - restart, restart, restart.
I even tried to boot from my superduper backup on my firewire disk - no dice there either. Strange. Anyone else seeing issues? Know how to get out of the bootup loop? Is this a problem with the most recent Leopard upgrade?

I'm in the exact same situation. It just keeps cycling through the boot, giving the startup chime, then the same thing all over again. Tried booting it every which way ("c" "option" etc.) and nothing has worked. The only difference between your ordeal and mine seems to be that I've never seen the install disc as an alternate option to the HD during the setup screen (where the image of the HD is on a blue background). Is there no other way to bring the computer back to factory settings?
p.s. I have a call-back appointment with an Apple tech in the morning, so if nothing better comes along, I'll probably have a solution around 10 tomorrow. In the mean time, good luck.=)
