Mac mini won't boot into target disk mode

Hi
I just bought a Mac mini on eBay. I'm not sure of the spec but I think its a G4.
When it arrived I plugged it in and switched on to find the question mark folder appear.
I put in a 10.5 disk but it would not boot from it. [this was a disk I got with another s/h machine though so may not be bootable]
As I could not install from the disk I figured my best bet would be to target disk in and install osx from a powerbook I have here.
However I can't get target disk to work.
The keyboard is definitely working as it allows me to boot into OF and zap the PRAM
I've also tried pressing what I believe to be the SMU button just behind the connector board to the HD and DVD drive but no luck.
Anybody got any ideas as to whats going on?
Cheers

Ok, I can probably get a copy of OSX
The problem is I think the DVD drive is faulty as it wouldn't give me my disk back I tried "eject cd" in OF but it didn't work and I had to open it up with a screw driver and take it out.
If the disk is corrupted is there a way to erase it without putting it in another machine. ie can it be done from OF?
Thanks for your help btw

Mac Mini won't Boot after Target Disk Mode

We just bought a new iMac and used target disk mode via firewire from our older Mac Mini running OSX 10.4 to transfer data. Now when we go to restart the mini, the grey screen appears with apple logo and it seems to try to boot up but after a long time alway just ends up with a blue screen. I don't think I "ejected" the mini properly from the imac after the target disk mode transfer. Could the mini be stuck in target disk mode? I've tried to restart in different modes eg. safe mode, pram by holding down keys on start up but doesnt make a difference at all almost as if the keyboard isn't registering (and its a wired keyboard). Any ideas???
Thanks

Try starting up from the Recovery Partition holding the Option (Alt) key and see if you can Repair your Macintosh HD, as per > OS X: About OS X Recovery

Pismo with Tiger won't go into target disk mode

I recently upgraded my Pismo to Tiger and can't seem to boot into firewire target disk mode. The computer restarts and gives me a terminal screen that reads: "can't OPEN DISK" and then goes on to say "Welcome to Open Firmware. To continue booting, type "mac-boot"..."
I tried zapping the pram, but that did nothing. Does anybody have any suggestions?

MacUser,
When booted in 10.4.8, select Target Disk Mode in the System Preferences > Startup Disk and see what happens.
If no success, try resetting Open Firmware (from Apple docs):
Boot into Open Firmware by holding down the 'Command-Option-O-F' keys from a cold start while the chime is being played. You will see a command-line screen...enter these commands:
1. At the Open Firmware prompt, type: reset-nvram
2. Press Return.
3. At the Open Firmware prompt, type: reset-all
4. Press Return.
Example:
0 > reset-nvram
Press Return
0 > reset-all
Press Return
The reset-all command should cause the computer to restart. If this occurs, you have successfully reset the Open Firmware settings.

what gives?

Won't go into Target Disk Mode

Help,
I have an iMac that is several years old, OS X v. 10.3.9, has never had any trouble. I recently bought a new MacBook Pro and have been trying to move files over from the iMac, but I cannot get the iMac to boot up in Target Disk Mode.
I reboot, hold the "T" key, etc., and the FireWire symbol comes up, but then it just slowly bounces around the screen while the machine whirs away, and I don't get any further.
Open Firmware Password is not activated; I've run software updates.
Any suggestions would be greatly appreciated.
Thanks

Hi,
A while back I tried what you have and also, the Panther OS G4 would not show up on the Tiger OS G4, although the Panther OS was in Target Disk Mode with the floating icon.
The connection was per instructions, both on line and step-by-step per the Tiger OS, but no disk showed up even after a few hours of wait.
What I found is that my Panther OS G4 Firewire socket was 'mushy' (it moved fairly easy from slight finger pressure on the plug-in end... it was not 'firm' like my USB socket was. So I tried a Firewire external drive I have, that did work before, and it too, did not show-up (although it did start it by being plugged in). Everything I tried with that Firewire socket on the Panther Computer was not there... although these did work on the Tiger Computer.
Since the Firewire is soldered onto the motherboard I have come to the conclusion that one or more of the connections are disconnected... perhaps not the power one, as the external items react to the plug-in, but there is no 'communication' after the fact.
Perhaps this is what has happened on the iMac end for you. And yes, I have used that Firewire plug many many times and not always with TLC in the past, as it is a laptop.
Now I use a Firewire 400 to Firewire 800 (either direction works, depending on what plug works on which item) for what I have and do... as to repair it would be more then a new computer and the Panther computer is an '05 model (but still used daily for what it does).
Maybe you can check how 'solid' your iMac feels when it is plugged in with the Firewire, compare it to other connections... do it gently though, but if it is loose you will know by the 'mushy give' it has.

Mac Mini won't boot with install disk

tried booting with install disc in and pushing "c" on keyboard and doesn't work. Using a apple wireless keyboard. Also used the keyboard that came with Mac Pro but didn't work nor did a wired logitech.
any ideas?
Thanks!

+What is the source of the idea that the mac aluminum keyboard won't work with the mini?+
Dozens of reports in this forum over the past year.
Keep in mind that by "not working" what was meant was that the startup keys wouldn't work. The Alu keyboard otherwise works fine with the Mini.
It has also been reported that the Alu Keyboard does work for startup keys if it is plugged into a hub with an external power supply.

Mac mini won't boot at all

I am currently using my mac mini (core solo) as a media center. I cam home from a long weekend to find it completely frozen, so i powered it off, and i have not been able to get it to boot since.
The regular startup screen appears, but it permanently hangs with the grey screen with the apple logo, and no spinning wheel.
I have attempted to boot from my Leopard disk with no success. I cannot boot into single-user mode. I cannot boot into safe mode. The only thing I can do is boot into target disk mode, which I have done in order to retrieve some files. I have also applied the 10.5.4 combo updater via target disk mode with no change in my problem.
When I boot in verbose mode, I can see some messages which may or may not be out of the ordinary, one example of which is:
+Extension "com.apple.driver.AppleACPIPlatform" has immediate dependencies on both com.apple.kernel and com.apple.kpi components; use only one style+
It has the same exact message for com.apple.driver.ApplePCIConfigurator and com.apple.driver.Apple.IntelCPUPowerManagement. I don't know if these are normal or not.
The last 3 lines where it stops booting are:
+rooting via boot-uuid from /chosen: 7FB33E59-0964-31AC-8244-283A02217CBA2+
+Waiting on <dict ID="0"><key>IOProviderClass</key><string ID="1">IOResourceMatch</key><string ID="2">boot-uuid-media</string></dict>+
+FireWire (OHCI) Lucent ID 5811 built-in now active, GUID 0016cbfffe59e93c; max speed s400+
Any ideas? At this point I'm ready to just format and re-install, but how can I proceed if I can't get it to boot to the Leopard disk?

LE Studios,
I also had a boot-up problem similar to yours, but possibly for different underlying reasons (RAM related, I think). Anyway, what sometimes happens is that your directory might be corrupted preventing the unit from accessing the boot-up files that it needs. You might try running Disk Warrior, a utility that is used by the genius bar at Apple Stores. It comes on a disk that you would use as the start-up disk.
Start up the unit and insert the Disk Warrior DIsk and hold down the "C" key. The software can take a while to load (3-4 minutes). When it's finished loading you should see the Mac Mini hard drive available for the program's routines. Choose the directory fix. If successful, you should be able to re-boot the Mac Mini normally once the new directory is written to the disk.
This may not solve the original problem as to why the unit froze in the first place, but it should allow you to boot the computer.
You may also want to run the Apple Hardware Test that is on the installation disk that came with the computer.

Mac Mini won't boot up.

Mac Mini won't boot up! Just getting blank white screen, any ideas why? No apple, just a blank screen. It worked fine last night.

Have you tried booting into the Recovery HD by pressing/holding COMMAND+R at system start or the Option/Alt key and choosing Recovery HD to boot into?
If you can get into the Recovery HD, open Disk Utilities and Verify Disk. Repair if necessary.

I put my macbook into target disk mode and now it won't start up in regular mode

I put my macbook into target disk mode and now it won't start up in OSX. I have used my install disk and repaired the drive. I have held down the option key to choose the system. I have tried to start in safe mode with same result. The apple screen appears, but the gear just keeps turning. I can get it back into target disk mode by connecting it by firewaire to my macbook pro. It will start up in Windows when I choose that system. What can I do to get it to start up with OSX?
Thanks for your help.

Try this from MacFixIt as well:
In the case of drive directory damage or problems with permissions, the solution is usually to use Apple's Disk Utility to repair the disk. Of course, you won't be able to perform this operation normally (simply launching the Disk Utility application, located in Applications/Utilities, and initiating a disk repair) if your system will not startup. So two options exist:
* Insert your Mac OS X 10.4.x (Tiger) media (DVD or CD) and restart the computer while holding down the "C" key. Once the computer has booted from the installation disc, select "Utilities" from the menubar and open Disk Utility. Repair the disk, then quit Disk Utility and restart your system.
* Alternatively, you can repair the disk while booted in single user mode if you do not have access to a retail Mac OS X 10.4.x (Tiger) DVD/CD. To startup in single user mode, hold down the "Command" and "S" keys simultaneously at startup. Once properly booted, type the command fsck at the prompt. Repeat these process until no errors appear.

Mac mini won't boot anymore

My Mac mini won't boot anymore. It's been running fine for months.
It's running Leopard Server 10.5.2 Build 9C31
It starts to boot, I get the first spinning gear with the gray screen, then the blue desktop blinks, then a second spinning gear on a gray screen and it appears to hang (the gear stops spinning).
I booted off the install DVD, ran disk utility, repaired the HD, repaired the permissions: the behavior is the same.
Safe mode doesn't work (same hang as above).
Single user mode does work.
I can connect to it via Server Admin while it appears hung.
The last few lines of the system log are:

Yes, it's been running Server since I purchased it.
I doubt the serial number is in use elsewhere: I purchased the 10-user version at a retail store in a sealed package and I've only installed it once.

Mac Mini won't boot after failed XP installation

Recently upgrade HD to 320GB 7200 rpm and 3GB ram. Running 10.5.8 fine.
I tried to install Windows XP through Boot Camp, but wasn't successful, I terminated the installation. Then Mac Mini won't boot up. When powered on, you heard the chime, then grey screen showed and stayed. Tried starting with "C" (boot from CD), "OPT" (boot option), "T" (target), and reset PRAM. None of them worked.
What should I try next?
Thanks

If you install XP on Bootcamp, your startup disc will be changed to XP Windows partitioned you did. To restore your startup disc back to Mac OS, make sure your Mac is turned off. 1. Plug the power back and press the power button ON. When you hear the power On sound, press and hold the ALT key on your keyboard until you see the hardrives. 2. Select the HD that says MAc OS, then your mac will boot back to Mac OS.
Let me know if you have more problems, maybe I can help.

Booting from target disk mode

I have a mid 2012 MacBook Pro on the way with a 500 GB internal HD. My old mid 2007 MBP has a 1T hybrid drive that I would like to install as is in the new machine. Both on latest Mavericks....will the new machine boot up with the 2007 1T hard drive. Can this be tested via booting from target disk mode ?
Thanks

1. Yes.
2. Yes, it can.

Mac mini won't boot - keyboard shortcuts don't work

Older Intel Mac Mini that I use as an entertainment / movie center. Leopard.
I did a software update recently, but somehow botched it and interrupted the process.
Ever since then, it won't start up correctly. It chimes, disk powers up, but then it gets stuck on the screen with the apple and rotating propeller. Can go on for hours if you let it.
Took it to a dealer, who said it started up fine from another system an I should try starting it in target disk mode an reinstall the OS.
Bought a USB keyboard specifically so I could press the T and tried it.
It seems that none of the keyboard shortcuts work. I tried target disk mode (T), starting from a system disk (C), tried having it give me a choice of bootable volumes (Option) - nothing. It would appear the Mini doesn't recognize my brand new Apple USB keyboard.
Tried the keyboard with my MacBook and there it works fine.
Any ideas?

OK, just found the answer while browsing the "more like this" answers that appeared after I posted my question.
I wasn't aware that the new Apple Aluminium Keyboard doesn't play nice with the Mini and that the Mini doesn't recognize this particular keyboard in time for the boot sequence.
Thank you for these helpful discussions:

https://discussions.apple.com/thread/1477855?threadID=1477855&tstart=0
Using the remote (press the menu key during boot-up) worked fine and I could choose to boot from a system disk.
Spending $60 for a new keyboard that won't do what I bought it for is, however, another story. Grr.

Mac Mini won't boot, distorted startup chime, gray screen

Hi all --
I've seen similar posts (http://discussions.apple.com/thread.jspa?messageID=12170891&#12170891) but thought I'd start a new one, mainly because I haven't heard anyone mention the startup chime.
I woke up my 2007 stock Mac Mini Friday morning and the cursor was frozen. Unplugged and replugged the mouse to no avail. Couldn't force quit, so I had to power down. Restarted with a badly distored startup chime (not "speaker breakup" from excessive volume, just distortion, and some "stuttering") and a gray screen that didn't go away. Restarted many, many times. Inserted Snow Leopard DVD to run Disc Utility but it wasn't recognized -- just a gray screen. Tried resetting the PMU and SMC with no results. Tried booting into single-user mode (with a wired USB keyboard) to eject the DVD, but no luck. Tried open firmware, but nothing. Once in an while I would get the Apple icon and a spinning progress bar that never went away.
Took it to the Genius Bar, where they tried to boot from a Firewire drive, with no success. The best they could do was tell me my 17-month old Mac was out of warranty. That confirmed, I took it home, cracked it open and removed the Snow Leopard DVD (with a credit card) to insert the install disc it shipped with. That didn't work. A couple of times it looked like it would, but then after the spinning bar I got the multilingual system bomb message. Tried to run Hardware Test, but nothing. Put in original Disc 2... and that gave me a flashing folder! Progress! Forced the DVD out and slipped in Disc 1. That started to read, and then I got some kernel-panic looking text and a shutdown. My last attempt was to create a USB boot drive from the original install discs, but my old Sawtooth won't let me run the installer.
Is there any hope at this point? I just bought the thing last May, so I've had it less than a year and a half. The distorted startup chime makes me think the logic board is fried and no amount of fooling with the startup drive will make a difference. The only thing out of the ordinary in this case was that it went to sleep last Thursday night with a DV camera hooked up via Firewire.
I'm not thrilled about giving Apple any more money for another Mini, but I'm heavily invested in Logic Studio so I don't have much of a choice of platform.
I'm pretty sure I'm doomed, but I thought I'd post anyway. A quick internet search shows I'm not the only one with the gray screen of death on a fairly new Mini. Thanks in advance for any pointers.

Thanks.
The Genius was able to get to the Apple logo and spinning... thing (what used to be the beachball). His theory was that as long as the Snow Leopard disc was in there, the boot process would never get to the Firewire port. Once I got home I literally pried the Snow Leopard disc out and put in the original install disc. But any progress whatsoever ends in the system bomb message.
Thing is, I had tried to eject the disc by booting with the mouse button down. But on restarting, the laser in the optical mouse flashes quickly, once. I don't think the USB ports are going "live" at all... so I can't get into single user mode, safe mode, hardware test, anything. The Genius' keyboard was no help in that regard. So yeah, I suspect a hardware problem.
A search of "gray screen of death" shows this happening to a lot of models.
