HT1661 Target disc mode not working

My target disc (Macbook Pro) shows the firewire icon but nothing shows up on the host (PowerMac). I've tried several different ways and enabled it to show up in preferences. I don't have any other firewire device plugged in. I'm using a brand new cable. Thanks

The cord was a very inexpensive one I got on Amazon. Could that be it?
It's certainly possible. Anything else you could try it on?
Also, there is only about 4MB of storage left on the host hard drive, though that shouldn't keep the target drive from showing up.
4MB??? I've never seen a situation like this, but I suspect it could indeed prevent the Target from showing up. The Host needs some overhead to make things work.
I'm running 10.4.11 on the host and Snow Leopard on the target.
I was going to suggest running Software Update on the Host, but with only 4MB of space, it couldn't install anything anyway.
The target is so full it won't show me anything but Safari, not even the finder, but it is going into target mode every time no problem.
Well, that kills my other idea. I was going to suggest switching Host and Target around.
At this point, I'd suggest getting some external storage so you can offload at least 10-15GBs (ideally, you never want to go under 15% free space available). Then try again.

Target Display Mode not working iMac 27(2012) Bootcamp to iMac 27(2013)

Hi All,
I recently purchased an iMac 27" 2013 which replaced my iMac 27" 2010.
===============
PREVIOUS SETUP
===============
(1) iMac 27" 2012 - Running Windows 8.1
(2) iMac 27" 2010 - Running OS X Mavericks
(1)+(2) were connected with a Mini-Display-Port cable.
(1) was using (2) as external display while (2) was set to Target Display Mode using CMD+F2
==============
CURRENT SETUP
==============
(1) iMac 27" 2013 - Running Windows 8.1
(2) iMac 27" 2012 - Running OS X Mavericks
(1)+(2) are connected with Thunderbolt cable.
(1) can't use (2) as external display anymore becuase CMD+F2 has no effect anymore on (2) in this scenario.
If (1) and (2) are both running OS X all works as expected.
I am aware about the support hint from Apple where they state TDM is not working under Bootcamp.
And I agree, while booted into Windows Bootcamp this machine can't serve as external display. Makes sense because TDM is baked into OS X display drivers.
Anyone had the same experience and came to a soltuion?
Thanks,
Martin

"Apple has no plans to implement a client driver for Windows since there is no Thunderbolt SW stack available for Windows like there is for Display Port."
That is a little bit funny since Gigabyte and other big companies have said that 2014 is the year that they are going to implement Thunderbolt in many motherboards.
"GIGABYTE 7 series motherboards are the very first to offer fully certified dual onboard Thunderbolt™ ports. Capable of connecting up to 12 devices plus 3 digital displays simultaneously with breathtaking data transfer speeds that can transfer 1TB of data in only five minutes, GIGABYTE Thunderbolt™ motherboards offer the fastest connection interface on the desktop PC."
Have you asked Apple about that? I dont understand why Apple is crippling Thunderbolt on their devices...

2010 iMac Target Display Mode not working

I'm trying to use my 27" 2010 iMac with OS X 10.7.5 as the display for my Power Mac G4 using Target Display Mode, but command+F2 doesn't do anything. I have it hooked up from the G4 using a DVI -> Mini Displayport adapter into the iMac. I've tried having the G4 plugged into the iMac, shutting both down, booting the G4 first and then the iMac. I've tried repairing my disk permissions on the iMac. I'm using an Apple keyboard and have tried both a wireless and USB keyboard, still no luck. Is what I'm attempting impossible or am I doing something wrong?

Target Display is working on the iMac, but by default, the MacBook Air uses the external display (in this case, the iMac) as an extended display, so you have to drag the windows to the right of the display of your MacBook Air and they will appear on your iMac.
If you want to show the same on both MacBook Air and iMac displays, see "Video mirroring" > http://support.apple.com/kb/HT5019

MacBook Air to iMac Target Display Mode not working

I would like to connect my MacBook Air (13") with my iMac (27") to use the latter as an external display with Target Display Mode.
I followed instructions from a number of posts (http://support.apple.com/kb/PH14264), and connected the two with thunderbolt cable and hit Command-F2 -- the iMac goes black and MacBook stays the same. One post suggested dragging windows over to the iMac as an extended display, and I was able to drag Safari totally off-screen, presumably onto the other display, but the iMac still appeared black
Other issue is that hitting Command-F2 again doesn't do anything. I could only get the iMac out of TDM when I unplugged the thunderbolt cord.
I have a brand new Macbook Air and iMac along with new thunderbolt cable (all purchased at Apple Store in 2014). Would appreciate any help, thanks!

Additional twist to this...
Tried to troubleshoot and reset the System Management Controller (SMC) per http://support.apple.com/kb/HT3964
When I hit Command-F2, one window from my MacBook will display on the iMac (it was Safari a few times, Outlook once), but neither keyboard/mouse can DO anything in that screen. That window also disappears from the MacBook. And I can only return after unplugging thunderbolt (not command-F2).
Help please

Ipod in disc mode not working on windows

i have an 80 Classic set to utilize disc mode. it mounts fine on my Mac (ipod is mac formatted) but when mounted on a Windows machine it wants me to format the drive.
any suggestions? am i missing something?

If you format iPod on Mac your iPod disk will save in Macintosh format and it will only use in Mac not for Windows (except you install some application to make Windows understand Mac OS X filesystem). But if you format in Windows (restore in iTunes on Windows) then you can use on both Mac and Windows.

Target Disc Mode via Firewire PC Card

I am unable to boot my PowerBook Ti in firewire disc mode as my firewire port died. Since i've been using a PC card with 3 firewire ports on it. When attempting to reboot in firewire disc mode with another mac it just restarts.
I surmise the issue lies in the boot order? Does the PC card load later than when an internal firewire port would become available?
Thanks!

Hello Nathan,
I believe the reason you can not use firewire disc mode is because you need to use the built-in firewire ports for target disc mode to work. The device information for the built-in firewire ports are loaded with Open Firmware as the computer starts up. I'm guessing that the PCMCIA card slot device information isn't loaded until after Open Firmware has loaded, thus making it unavailable for firewire target disc mode.
Hope this helps!
Hi O,
In my experience, the superdrives are reliable and i wouldn't worry about it breaking. That being said, all drives will die eventually, but the superdrives seem to be well built and usually last a long time. Replacing an optical drive on a 12" AL powerbook is actually quite a pain. You basically have to remove everything, including the logic board, to replace it. I wouldn't recommend replacing it yourself unless you have the proper experience and tools required.
Hope this helps!

Target mode not working restating holding T

How do I restart in target disc mode with MAcbook pro , firewired to another mac, restarting holding the "T". It is not working, I have to go to system preferences > startup Disk > and do Target Disk mode.
Before I could just hold the "T " on restart and it would do it. How can I make that function work again?
THX _________

Make sure the FireWire cable is good, and check the connection.
Make sure no other FireWire devices are connected.
Make sure you are starting up the computer while pressing and holding down the T key.

Core i3 mac not seeing power pc g4 imac in target disc mode

I'm trying to migrate my set up from a power pc g4 imac running a 10.4.11 to a core i3 imac. All the system software and firmware on the g4 imac is upto date and the mac will enter target disc mode. The macs are connected using a brand new 6 pin to 9 pin firewire cable. The iMac core i3 will not see the other mac in target disc mode. When trying the same thing using the migration assistant, migration assistant just hangs with the 'waiting for your other mac to restart'.
I'd really appreciate any help to fix the issue.

Is this the newest model with Thunderbolt? If so then see Thunderbolt 10.6 Help: Transferring files between two computers using Target Disk Mode and Intel-based Mac may become unresponsive in target disk mode.
Have you checked to be sure the drive in the G4 is configured as the Master? If it isn't, then it cannot be seen in TDM.

Target Disc Mode doesn't Work - what do I do?

So my old Apple (2004 G4 Powerbook) went out on me. It will start it up but it won't advance past the start up screen. So I bought a new Apple. I have followed the instructions on how to transfer data from the old one to the new one using the Target Disc Mode, and the Migration Assistant. I can start my old one up in Target Disc Mode (the FireWire icon shows up on the screen). However, my new computer won't recognize it. In the migration mode, all it says is "searching for disc". It doesn't show up on my desktop either (my understanding that it should when in that mode). Any ideas of what I can do? I really want to be able to transfer that data over...Thanks in advance!

Hi and Welcome to Apple Discussions ...
Sounds like the drive in the PBookG4 has failed but I never say die. If by chance you use Airport and have a wireless network set up, you might be able to access the PBook drive with the new Mac. On the new Mac, make sure Airport is turned on. Open a Finder window, select Network in the Sidebar on the left and then click Network.
On the PBookG4. You say it starts up but not past the start up screen. Have you tried using the restore disk that came with the PBook and using Disk Utility to possibly repair the drive? If not, and you have the restore disk, post back and I'll give you the instructions to do this.

How to use and troubleshoot FireWire target disk mode
Summary
Learn how to use and troubleshoot FireWire target disk mode.
Products Affected
Desktop Computers, Mac OS, Portable Computers
FireWire target disk mode allows a Macintosh computer with a FireWire port (the target computer) to be used as an external hard disk connected to another computer (the host). Once a target computer is started up as a FireWire hard disk and is available to the host computer, you can copy files to or from that volume.
Host computer requirements
Host computers must meet these requirements:
Built-in FireWire port or a FireWire port on a PC card
FireWire 2.3.3 or later
Mac OS 8.6 or later
Target computers
These models can be used as target computers:
iMac (Slot Loading) with Firmware version 2.4 or later
iMac (Summer 2000) and all models introduced after July 2000
eMac (all models)
Mac mini (all models)
Power Mac G4 (AGP Graphics) with ATA drive
Power Mac G4 Cube
Power Mac G4 (Gigabit Ethernet) and all models introduced after July 2000
Power Mac G5 (all models)
Mac Pro (all models)
iBook (FireWire) and all models introduced after September 2000
PowerBook G3 (FireWire)
PowerBook G4 (all models)
MacBook Pro (all models)
MacBook models introduced before October 2008
Read more about FireWire Ports and Specifications.Note: FireWire Target Disk Mode works on internal PATA or SATA drives only. Target Disk Mode only connects to the master PATA drive on the Ultra ATA bus. It will not connect to Slave ATA, ATAPI, or SCSI drives.Before attempting FireWire target disk mode, check these items:
Make sure your software and firmware are up to date.
Disconnect all other FireWire devices from both computers before you use FireWire target disk mode. Do not connect any FireWire devices until after you have disconnected the two computers from each other or have stopped using target disk mode.
If "Open Firmware Password" has been enabled the computer will not go into Target Disk mode. More information on Open Firmware Password is available in the "What to do if your Mac doesn't enter FireWire Target Disk Mode" section of this article.
If you will be transferring FileVault-protected home directories (Mac OS X v10.3 or later only), log in as the FileVault-protected user and temporarily turn off FileVault. After transferring home directory contents to the target computer, enable FileVault protection again if you like.
To use FireWire target disk mode
Make sure that the target computer is turned off.
If you are using an Apple portable computer such as a PowerBook or MacBook as the target computer, plug in its AC power adapter.
Use a FireWire cable to connect the target computer to a host computer. The host computer can be powered on.
Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. The hard disk of the target computer should become available to the host computer and will likely appear on desktop. (If the target computer is running Mac OS X v10.4 Tiger, you can also open System Preferences, choose Startup Disk, and click Target Disk Mode. Restart the computer and it will start up in Target Disk Mode.)
When you are finished copying files, locate the target computer's hard disk icon on the desktop of the host computer and drag it to the Trash or choose Eject (or Put Away) from the File menu.
Press the target computer's power button to turn it off.
Unplug the FireWire cable.
Tips for using target disk mode with Intel-based Mac computers
If you attempt to mount an Intel-based Mac in target disk mode on a Macintosh running Mac OS X v10.3.9 or earlier, you'll see an alert message. For more information, see Intel-based Macs: "You have inserted a disk containing no volumes that Mac OS X can read" alert message.If your Intel-based Mac is becoming unresponsive while in Target Disk Mode, refer to Intel-based Mac may become unresponsive in target disk mode.What to do if your Mac doesn't enter FireWire target disk modeIf your computer does not enter FireWire target disk mode when you hold down the T key at startup and instead starts up into Mac OS, try these steps:
Make sure the FireWire cable is good, and check the connection.
Make sure no other FireWire devices are connected.
Make sure you are starting up the computer while pressing and holding down the T key.
Check the keyboard connection. Make sure the keyboard is connected directly to the computer and not through a display or hub. Whenever possible use an Apple wired or wireless keyboard.
Make sure that Open Firmware Password has not been enabled on this computer. Depending your OS version you may need to download the Open Firmware Password software. For more information on Open Firmware passwords, review Setting up firmware password protection in Mac OS X.

Installing tiger on an ibook w/o dvd, but using target disc mode?

so here is the problem. i bought tiger for my ibook (g3 500mhz 312 mb airport cd drive...) so i found out the hard way that i can not install tiger dvd on my ibook (it has a cd drive.) so i was thinking and booted it up in target disc mode on my g4 tower running 10.2.8 the hard drive came up on the g4 and i installed sucessfully tiger on to the ibook! i was really excited that it worked. (i really didn;t want to order the cd set from apple)
so i went to start and download updates and it didn't connect. so i went to configure the airport and had a ton of problems. it just won't! airport will not recgonize any networks, and i have done it all to configure it. the ibook sees the card too!
so i took the card out of the ibook and installe dit in tehg4 tower and bravo it works just fine, so the problem is not the card at all.
i then took the ibiik to firsttech (an apple store) and they booted it up in network mode and the card worked just fine! they think that because i installed tiger fro a computer that was not running an airport network that it did not install that part of the software. this i do not believe becaust all of the airport stuff is there to configure, the problem is it just won't.
so to make things more interesting the screen will freeze. and after that when i reboot the ibook the screen is dead. and it stays dead for a while so this is just a pain. i try to reboot it in target disc mode but the icon does not show up on the host computer. i can run system profiler and the g4 will see the ibook as a firewire device in target disc mode, but i just can't see it on the desktop. i can hear the hard drive running, and i get the chime so i know it is on.
so i know that the problem is probably tiger as i know that there have some problems with it. but i just don't get it. b4 i reinstall 10.2 can anyone give me any help fixing tiger?
THANKS!

Hi sean,
first of all: WELCOME TO THE DISCUSSIONS!
You probably did the target-disk install the wrong way round. If you booted the G4 from the install DVD and from there installed Tiger to the G3 iBook you have installed the G4 hardware drivers which are not compatible with the iBook.
You have to do it this way:
Insert the install DVD into the G4. Start the G4 into target disk mode by holding down the t-key during boot. Connect the G4 to the iBook using a firewire cable. Now boot the iBook while holding down the option-key. This will bring you into the boot manager where you can select the install DVD as boot-volume.
Once the installer has started perform an Archive&Install to the iBook hard disk. This should solve your problem.
Remember: Repair permissions before and after an update!

Using target disc mode to access a broken laptop

I'm using a 1.33 15" PB with 10.3.9
and broken early 12" still on 10.2.8
During an attempted repair of the 12" DC in jack, also replacing the broken CD/DVD Drive with a SD using a replacement lower case and screen that still had the screen control? and dc in jack in it, broke the connection for the screen control on the 12" logic board, Thought I had it effectively soldered back on, but appears not. Screen won't light up, But appears to powering up, get the dong and hard drive spins up.
Was told to connect the two units together with firewire and use the Target disc mode to access the data on the broken machine. (which normally needs to be logged into on start up normally, but can't, not being able see the screen)
With the 12" powered up, I restarted the 15" holding the "T" key down and get a screen that has a Yellow "Y" like icon that moves around the screen, "O" with 3 extensions off it, 1 solid and other 2 dashes.
After a minute or so, shut it down, now sure if it was eventually going to work or should have waited longer. or done something else?, Was expecting the normal desktop to show up with some kind of icon for the other computer, then maybe figure out from there how to transfer the data to the new unit.
Have no idea what to do next or what the problem might be, if I'm doing something wrong, or have to change settings somewhere on the 15" before doing it?
This a used unit, with a fresh 10.3 install and upgraded to 10.3.9 Haven't even gone into the system preferences yet and don't know what most of it's for anyway, (Just did the initial set up) or if the 12" has hardware problems still, etc,
Have a USB external HD adapter and can take the HD out of the 12" instead and see If that'll work? But still not sure if I'm going to encounter something else again that's not easy to figure out in order to get the data off it. Transfer it to the 15" or be able to use it on the external drive
Thanks in advance, And hopefully simple instructions....

Thanks, That eventually worked, Oddly produced an open OS 9 Virtual PC 3 Application folder on the 15" desktop that I installed on the 12" long ago and never used before the external drive icon as I named it for the 12" showed up
Clicking on the external hard drive icon had it open the 15" system folder? Hard drive content window (the os 10.3.9 having a different format than what I'm used to seeing)
All the familiar folders from the 12" were there, but the couple times I tried to open one of them, the external hard drive icon and related entire open desktop window, (Hard drive content) disappeared and produced an error message to properly eject the item, But there nothing there to eject anymore, subsequent attempts to get it back failing, But eventually got it up again.
But can't open the 12" mail application to retrieve my old emails and can't seem to find the file to rebuild the 15" mailbox into what I had in my 12" or save/find those emails, but not sure where to look, must be files somewhere for them.
Every time I click on the mail app in the 12" file, it pops down into application bar and disappears. Tried dragging it into the 15"s icon and that not doing anything either. Also dragging it into the app tool bar and trying to open it and it doing nothing, Presume unable to in the later os.
Will this still happen if I take the HD out? and connect with my USB adapter? Need to boot from this? (have no idea how to do that)
Any suggestions on where to find my old mailbox files? Tried opening a number of odd files in the system folder and found nothing in some of them.
I'm presuming this isn't working because it's still an OS X 10.2.8 application But all the other files appear to still be there and think I found the mail before at one time.
Also got an error in iphoto, Can't open it because it needs to be opened in the later version. But found the 12" iphoto file and dragged it to the desktop and took a bit to transfer, so presume I should move it or specific files in it into the 15" iphoto 15" file to retreive the photo's. (and also moved my camera app to reinstall) Same with my itunes which only had a few cd's in it.
The 12" desktop also took a bit to find, but moved that file to the 15" desk top and those files took a little while to transfer. Some of those are MS Word files so also moved the MS Word app and expect to need to reinstall it before trying to open any of those word doc's.
Still wonder why it produced that os 9 as an open folder which was a virtual pc 3 program I never got around to using,

Target Disc Mode

I am trying to use my G4/1GHz B&W Yosmite as the Host, to a G4/17" flat screen iMac as the Target. The iMac enters Target Disc Mode (a yellow firewire icon is moving around the screen), but its drive icon does not appear on the Host. Both computers are running 10.4.5. I have tried restarting the host and hot plugging the firewire cable. The cable is off my iSight camera, which works on both computers. Any help would be much appreciated. Thanks. Tony

Target Disc Mode + Disc Mounting issues

I hope this is a suitable forum for this topic.
Anyway, I recently posted a question concerning the connection of 2 Mac's (one disabled), in order to save the contents of the disabled MBP.
I have since obtained a 6 pin to 9 pin cable (to connect my MB's FireWire 400 to MBP's Firewire 800), and have tried to access the MBPs hdd via Firewire/Target Disc Mode.
I have no problems booting the MBP to Target D. Mode, but the disc will not mount on my Macbook.
The main problem that I have noticed is the S.M.A.R.T status on the MBP's internal drive is saying "not supported". From what I have read this is a common status message for 3rd-party installed harddrives, but my internal is the factory installed drive.
Im pretty sure I know the answer: The drive is dead, ie. get a new one. But I just thought I would ask the you guys if there is some way to "fix" the SMART status so that it will mount.
Also, (and this is what makes me 99.9% sure the drive is dead) when linking the 2 computers in Target Disc Mode, the Leopard Install disc that was in the optical drive of the MBP was read on my Macbook, so I know the Firewire cable/both ports are in working order.
Hope this makes sense, as I tend to ramble!
Thanks for any help or suggestions,
Matt

If the drive does not mount and is otherwise inaccessible then booting into Target Disk Mode isn't going to help you. A drive's SMART status is not reported over FireWire or USB. The SMART status is only reported for the internal drive, locally. SMART has nothing to do with whether the drive is working or not. It is merely an information report.
All that you can hope to accomplish might be to purchase recovery software, boot the computer from the recovery software DVD, and hope something is recoverable. Or you can send the drive to one of the many disk recovery businesses to see if anything can be recovered from the dead drive.
File Recovery Software
Data Rescue
File Salvage
TechTool Pro.
The first two have demos you can download. The demo will indicate what if anything is recoverable, but until you pay for the software and get a serial number you cannot recover anything. You would also need the bootable DVD. This will not work if the drive's motor is dead or if the drive's interface board is no longer functioning. Both of these render the drive inaccessible. In this case recovery would have to be through a data recovery service like Drive Savers.
Each of the preceding comes on bootable CD.

PB will only start in target disc mode, please help

On normal start up, I get the "You need to restart your computer......" message with start symbol behind the writing. every time I try to restart the same thing happens. I've tried all the keys on start up tricks and the only ones that work are option/startup where I can choose Hard Drive, OS Disc, or Hardware tools. If I choose Hard Drive, it goes back to the kernal panic screen with "you need to .....". If I choose OS Disc, it goes to a light gray screen with the apple symbol in the middle and just stays there (also does this if I try to startup holding C with startup disc). If I choose Hardware Tools, it lets me test the hard drive and everything checks out fine but when I restart back to the "You need to restart.....". It will also startup in target disc mode hooked up to my iMac. All of my apps and files were there so I transfered everything, whew! I can then insert the startup disc into the PB and it comes up on my iMac in target disc mode. I then try to open and reinstall OS 10.4 but it tells me I have to restart to start the process and I can't do this in target disc mode. I just ant to be able to erase everything on my PB and reinstall OS 10.4 with the PB start discs. Is this possible? thanks....
J.R.

Seems to me you have made all the right conclusions yourself: your HDD checks out fine, you were able to retrieve all your other files in Target mode, so it must be some corrupt OS files.
You just need to startup from your 10.4 install CD#1. To do this, just put the cd ready in its slot, push the power button while pushing the C key at the same time, and gently push in the CD whenever the system is ready (hold the C key while doing this and for as long as needed to hear the PB starting up from CD). If this works, you'll be duly prompted for the rest of the install process.
Before restoring your backup, it may be a good idea to restart in target mode and recheck the hard drive in Disc Utility or preferably Techtool (run a surface analysis to make sure the disc has no bad blocks). If you find any bad blocks, discard the harddisc: it will have caused your OS to be corrupt, and is not to be trusted anymore.
Good luck!
