External Clone will not Boot PPC Mac

I have a ppc mac running OS 10.5.8 and an external hard drive, formatted with APM and containing a clone of the ppc mac. Using the firewire interface, this external drive will not boot the computer. The external HD box is an OWC Mercury Elite Pro containing a 2 TB Seagate Barracuda HD with 2 partitions, one partition containing the clone.

Does it only happen using FireWire? Have you checked if the external disk has got an Apple Partition Map? Note that it's required to start a PowerPC-based Mac.
To check that your external disk is using Apple Partition Map, connect the external drive, open Disk Utility and choose the external disk in the sidebar. Then, look at the bottom of the window and see what says next to "Partition Map Scheme"

Windows won't give a kernal panic or BSOD because it is a Mac related hardware issue.

Your asking about a Mac Pro, but those are not "G5" and the OS can't be transferred between PowerMacs and Mac Pro.... are you sure we are talking about only Mac Pros?
Putting XP and Mac OS on the same drive, that doesn't strike me as what one would do; keep them on different drives.
And, if they are on the same drive, then you really haven't reformatted the drive, which would involve wiping any and all partitions, and then creating your Mac Standard (HFS+ Journaling) and backup XP with WinClone or install it to another drive.
I don't have trouble with Windows, but I do with the Boot Camp Assistant and drivers.

External drives will not reformat to Mac OS Extended

I just moved several external drives from a PC to a Mac permanently and want to reformat them to Mac OS Extended. However, when I attempt to do it, I receive an error message saying that the formatting was unsuccessful after the disk is already erased. I am able to reformat them to DOS on the mac and the drives do work for some functions, but I need them formatted to Mac OS Extended in order to back them up with Time Machine.
The drives are fairly new; one is a Western Digital "My Book" 1TB only a few months old; the other two are LaCie "Big" 650 GB drives about two years old. They work fine, except for this one problem.
Any suggestions will be greatly appreciated.

You need to do the following:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Macbook pro will not boot into Mac OSX

When i got my MacBook Pro it would boot into Mac OSX fine. Now it wont even give me the option and will only let me boot into Windows which i have running through bootcamp. I have tried reinstalling MacOSX but my OSX installion DVD will not get recognised and i cannot boot off it either. I have tried using 2 other discs still with the same issue. The confusing thing is that the CD/DVD drive works fine and the MacOSx discs work fine in other macs as i have tried it in my brothers machine.
Any help appreciated.
Thanks

I don't think that the laptop even has Mac installed anymore becuase in an attempt to reinstall Mac the partition was formatted. And I can't boot of the disc becuase it just ejects by itself after a few seconds in the drive.

Hard Drive Full - After Reboot, Will Not Boot to Mac OS - Boot Camp OK Tho?

Hello all,
I having a severe issue with my 2007 Macbook Pro 2.33 w/10.6.xx (I believe I'm up to 10.6.2). Yesterday I was on the net in Firefox and got a message from the OS that my hard drive was full and that I had to kill some running apps to recover needed virtual memory. I killed everything but Firefox, finished my web-based game and shut down. The next time I attempted to start the computer, it would not go past the "gray screen with Apple logo and spinning wheel". In fact, if I hold the option key at startup, I can see my Windows Boot Camp partition, any bootable CD/DVD I might have in the drive and "EFI Boot" only. I cannot see Macintosh HD as option.
Here is a list of things I have done/tried:
1. The day before yesterday, Mac OS (10.6.xxx) informed me on my 2007 15" 2.33 MBP that it was out of HDD space and I needed to kill some apps to recover virtual memory.
2. I force killed everything but FF since I was in a game of Settlers on Asobrain at the time!
3. The computer ran fine for the rest of the session.
4. When I rebooted, all I could get was gray screen and spinning wheel.
5. I forced shut down, tried again, same thing.
6. I tried resetting PRAM with Ctrl-Cmd-P-R at startup, same thing.
7. I tried booting to safe mode. I got past login but it never loaded anything but the default background wallpaper. I shutdown.
8. I booted from the Snow Leopard DVD and ran disk verify, then disk repair but it could not be completed as the drive has been "corrupted".
9. At this point all I get upon startup now is Gray screen w/ Apple, then spinning wheel with progress bar that never goes anywhere then it shuts itself down.
10. When I start the computer in Target Disk Mode (TDM), only my Boot Camp partition will mount, not my Mac HD
11. *I do have boot camp installed, with XP Pro, and it will boot without a problem. In fact, I have HFSExplorer (a free utility f . or reading HFS volumes while in Windows) installed on the Windows side and I can see/browse folders on the Mac partition, so on the fact alone that I can boot to windows I know I don't have a HDD failure.
12. I have also tried booting to Single User mode which worked, I got the prompt. I tried using the "fsck -fy" command and it could not repair the volume.
13. I have tried creating an image of the Macintosh HD while in Disk Utility booted from the Mac Install DVD, but I get an "i/o error".
Please help! Any good suggestions, help, etc. is much appreciated! -Kyler

Hello and welcome to the discussions. All OS X drives need to keep 10-15% free space. If you were operating with less that that capacity, it is quite possible that some files were overwritten. Thus corrupted. The only thing that I could suggest is to try to copy your drive to an external HD or another Mac (Space permitting) Then reinstall using the install disc. You will then have to physically copy files from the external to your new install.
How large was your HD and how much free space does it have? You can use the install disc and Disk Utility to find out.
Cheers,
Glynn

My External HD Will Not Boot Up

Hi, I have been using my external HD (OS 10.2.8 with OS 9.2.2 installed) as my boot-up disc without any problem. This morning when I woke it back from sleep, the spinning ball appeared. So I rebooted and somehow my external HD failed to mount. I then rebooted via my internal HD and was able to repair the permissions as well as using Disk First Aid to repair the disc. But my external HD still won't mount. I then rebooted and no external HD. When I pushed the "option" key at start-up, I couldn't see the external HD either. Then I unplugged my external HD and plugged it back in, occasionally my external HD was able to mount but when I chose to reboot from it, my Pismo wouldn't reboot and it always stop at either "Waiting for local discks" or at "Waiting for Apache Web Server" options at the start-up window.
Also couple of times when I rebooted from my internal HD, I was able to mount my external HD and open any folders inside it. But whenever I chose it as my start-up disc, it would not reboot!
If anyone has any idea how to solve this problem, I would be greatly grateful. No new software has been added lately and also I just used Norton Anti-Virus to scan my Pismo (from my OS 9.2.2 of external HD, and no problem was found. After that, the problem started.
So any assistance/comments will be much appreciated.
Thank you.

Well, it has been several months since I first posted about this problem. In the last few months I have been waiting for my backorder of A/C adapter from Western Digital and in late January they informed me that the adapter I ordered is no longer available from Western Digital. So I went to eBay (which I should have done in the first place) and immediately found a replacement for my adapter. I ordered it and it came a week later. I plugged my supposedly dead external HD with the new adapter and guess what, it started spinning and mounted on my Pismo desktop. Then I rebooted my Pismo with the External HD and it was successful. All the files/folders and my 3000+ songs on iTunes were all there! Then I upgraded it to 10.3.9 and I have been using my External HD for a couple of weeks now without any problem.
This taught me that never give up until all alternatives have been tried. I had emailed Digital Western and explained to them the situation and they insisted that my HD is dead and said trying a new A/C adapter would probably do no good. So they were wrong!

IMac will NOT boot into Mac OS X!! [URGENT]

(not sure what section this goes in)
After a failed install of Ubuntu 10.10 via BootCamp (was unable to install due to it not picking my wireless keyboard up, I'm unable to get a wired keyboard) I ejected the install disc but I'm unable to boot back into Mac OS X. Holding down the Option key while it's starting up does not work. I also tried booting into Safe Mode, didn't work either. I'm currently on my mother's computer because I am unable to use my iMac. How can I solve this?
When it boots up, it plays the startup sound then goes to a black screen with a flashing white text indicator thing.

Nevermind! My grandma brought a USB keyboard over.

IMac 24' green & magenta vertical Lines will not boot.

Firstly let me say Hello all ^_^ Secondly, I hope this is posted in the right forum. :Oops:
The problem started a few days ago when my iMac went into screen saver mode and the whole screen had frozen and become pixlated with squares and a general scrambling of the screen, noise, grain, etc.. It wouldn't awaken from it's slumber so I did a hard restart.
The familiar friendly chime greeted me but the screen was covered in Vertical Green lines that are full of pixels, moving almost like static. The apple logo appeared and the spinning gear but that stopped spinning after about 20 - 30 seconds.
When I tried to boot into Safe mode this happened to the Apple logo (after about 3 or 4 mins)
The apple genius' are booked solid till next Thursday (27th) so I decided research and trial an error were my best options.
The following are the steps I have tried and where I am currently. Sorry for the lack of punctuation, etc...
On startup, Chime sounds, green vertical lines with what appears to be static, sometimes with Magenta in.
Apple logo appears
spinning lines lock up after about 10 seconds. Freeze.
Will not boot into Safe mode (by holding Shift after chime)
Will not boot from Mac OSX disk (by holding C after Chime)
Tried zapping the Pram (Shift, option, p & r on chime, Wait for 3 chimes)
Removed RAM 1 at a time tested in other slots, no change.
WILL enter into single user mode (holding Shift & S after Chime) so ran fsck twice to receive the Hard drive OK message. PHew Hard drive is OK then.
Reboot from here, same Vertical Magenta and green (sometimes just Green) Lines with static, Apple Logo, Spinning gear and freeze.
So connected with firewire into target disk mode. (connect mac book pro to imac using firewire cable and hold down the T key on your target computer, in my case my iMac) This essentially makes the imacs hard drive into an external firewire drive. Hard drive OK. Backed up. YAY. (most relieved to get back photos & current work)
Thanks for bearing with me on this epic post. ;);) and thanks in advance for sharing the knowledge.

Maybe this is a little late since this was last year but I thought I would post what the actual problem & solution was.
I took the iMac into see the Genius' and as it turns out it is indeed the graphics card. Luckily enough for me my iMac was just before they started soldering on them onto the logic boards AND it's one of the known faulty Nvidia Cards, which means a free repair, (luckily)
It took about 2 weeks to repair. when I recieved my iMac back unfortunatly there was lots of fingerprints inside the screen. Let it be said that the Mac store in Oxford street are the fairest of all, as instead of taking the machine and re-repairing, they replaced the whole iMac for a new one.
I hope anyone with this problem, or any other, has the same level of care from Mac as I have had.

Mac Mini i7 (Mavericks) will not boot from the external drive

Mac Mini i7 (Mavericks) will not boot from the external drive with Disk Warroir 4.4. or Drive Genius or Lion.
Not even from the external Firewire hard drive with Mavericks

Does the external HD have a GUID partition table?
Is the external drive formatted Mac OS X Extended (journaled)?
Is this a 2011 or late 2012 Mac?
How was Mavericks installed on the external drive?
Who is the builder of the drive mechanism in the external drive?
Who is the builder of the external enclosure?
What type of interface does the external drive have USB2, USB3, Firewire 400, Firewire 800, thunderbolt?
Is the external enclosure directly connected to the mini?
Have youtried a different interface cable?

2009 Mac Book pro will not boot up. I've tried to do a disk repair it says ETF partions need repair. When I try it says unable to unmount disk. I've tried to re-install the OS and when I do that the message says unable download.

My 2009 macbook pro will not boot up and I have tried everything to get it to work. Please help!!!!!!

Do you have an external drive? If no, then you will need to purchase a drive so you can backup your data.
If you have a drive that is formatted as GUID you can select to install OS X from recovery mode on the external drive. Now you can boot from that drive and make a backup of your internal drive so you can erase and reformat the drive.
Recommended Drives
USB 3.0 drives work on USB 2.0 but you do get 2.0 speed. They are cheaper because they are popular PC drives. If you get a new computer you'll get the bump to 3.0 speed. I don’t recommend FW. The newer computers don’t have FW ports. You would need a connector in order to use the drive on a newer computer.
Size: I recommend either the 2T or 3T drives. Often they are cheaper than a 1T drive. The 4T drives have more issues and failure rates.
Many drives come formatted for PC but easy to format in Disk Utility.
This Western Digital drive has good reviews: Has a 2 yr warranty. Comes formatted for Mac but I would still format using Disk Utility.
WD My Book Hard Drive for Mac 2 TB (WDBYCC0020HBK-NESN) $99
WD My Book Hard Drive for Mac 3 TB (WDBYCC0030HBK-NESN) $119.99
Check the warranty when comparing. The longer the warranty the better the drive. WD makes cheaper drives but with almost no warranty.
Locally, Best Buy seems to have the best prices.

Mac Mini (PowerPC version) will not boot - or reinstall...

All of a sudden my MacMini is playing up. It will not boot. I have tried leaving it overnight and reinstalling the OS to no avail.
It boots from CD and reads the install disc, but it hangs everywhere for ages. It verifies the install DVD - then just fails to install. And I have tried installing to external USB drives too with the same result.
I have run DiscWarrior twice and that sees no problems...any ideas? Any help will be greatly appreciated,

External Firewire Drive Will Not Boot with 10.5.1

I have a Intel Mac Mini and I tried to install Leopard onto a external Firewire Drive. I have done this with 10.4.11 and all works well. The Mac Mini is running 10.5.1 on it's internal drive. I attached the Ext FW drive 320 GB and formatted it using 'Disk Utility' GUID format. I next installed 10.5.0 on the Ext FW Drive. I can shutdown and reboot with 10.5.0 using the firewire drive as the booting drive. I next installed the 10.5.1 update and when it completes it requests a restart, I restart it and it never boots back up just the Grey-Apple screen.
I have left it sit for a long time in this 'trying-to-boot' mode for a longtime because I know 10.5.1 may restart more than once on initial install. but nothing. I have also tried partitioning the drive into 3 40-80-180GB drives, but still the same behavior.
Any suggestions?

Went through the motions on that. No positive results. I'm starting to suspect either the enclosure or one of the latest updates.
This what I have found to date.
The Enclosure " Vantec NexStar 3" extrenal USB 2.0 and Firewire. Model NST-360UF-BK
The Drive Seagate Barracuda 7200.10 320 GB IDE Drive
I tried 10.5.0 on an Intel Mac Mini. (GUID format) It boots ok. Install 10.5.1 manually downloaded or automatic it will install the update but will no reboot.
(this part I have to verify a second time) tried the same enclosure on a G4 . I attached the drive formatted it for a PowerPC install and boot. Installed 10.4.10 but not the latest security updates, JAVA, and QT. It will boot ok from the external FW drive. I next install the latest Updates via the update app in the Systems Preference window. After doing the updates for 10.4.10 it will not boot.
So I'm suspecting either the enclosure or the latest updates

Mac will not boot up, white screen with turning gear for hours on end

mac will not boot up, white screen with turning gear for hours on end

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 9
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Repeat Step 9, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
