OS X :: Booting Up From A Computer In Target Disk Mode?
Jul 12, 2008
I'm just curious if it's possible to put my Mac Pro into TDM, connect it to my MacBook Pro, start it up holding option to choose a start-up disk, and use the Mac Pro's HD to boot up. I'd experiment myself, but the Mac Pro is packed at the moment, and I'd like to know if anyone knows for sure that it will or will not work before digging it out.
I have a 15" mbp with 10.6 Intel core duo, 4gb ram with a boot camp and ubuntu partition through parallels. The other day I was installing xcode from apple's website, which failed 3 times after downloading saying the package couldn't be expanded. I left my computer for a while and came back where i then had to log in again. it rejected my password numerous time (i'm positive it was correct). when i restarted my computer i got a kernal panic screen when the apple logo came up. it told me to restart the computer which i did. didn't work. i restarted with the osx cd to use the disk utility. when it checked the drive it found a bunch of errors, which i then tried to correct. it went for a couple minutes then told me they couldn't be fixed and i should try to back up my data and reinstall osx. i don't know how to back up my hard drive when i can't log into my account. i've tried to boot in target disk mode and copy some files that way, but the only disk the other computer sees is my windows partition- no mac partition.
i've also tried these, none of these have worked: restarting in safe mode resetting the ram and pram booting with different sticks of ram all result in a kernal panic.
my windows partition still works fine though (as much as i hate to say it) the only things I really care about on my computer are my files from school and my itunes library. is there any way i can get these files off my computer?
Trying to troubleshoot a macbook pro 2.4 ghz with c2d so I start it up in target disk mode connected to my imac. (The current issue I am having are kernel panics on start up asking me to power off and restart). I am trying to see what the console output for the mbp is, but when I choose the mounted disk and go to applications there and run console, I get the console messages of my imac? What am I doing wrong guys?
edit: for the time being I ll just restart it in verbose mode, see what I get from that.
I need some pictures from my g4 digital audio onto my macbook, so I started the power mac up in target disk mode with the firewire cable attached, and it didn't mount. I have restarted both computers, and still the disks don't show up in disk utility. Could I have a bad cable, or is something else the problem?
I'm purchasing a new MBP and I'd like to migrate my files using target disk mode, rather than Migration Assistant. Are there any good support articles online that outline best procedures for doing this?
Transferring my documents should be pretty simple, but I just want to make sure that when I transfer my iPhoto/iTunes libraries and the like that I'm transferring the right files to reconstruct those libraries, without transferring over any old files that are unnecessary from my previous system.
Is it possible to boot a macbook pro retina using an external usb3 hdd (=hdd of my previous macbook pro), and boot via target disk mode, so I can carbon copy everything to the flash memory of the new macbook ?
In principle it sounds simple, but does anyone know if it can really happen? Can it boot from usb3 in the first place? (it's faster than usb2 and fw800 so I don't see why Apple wouldn't support it).
It's important to find out before I go ahead and buy the new laptop.
I thought having a Macbook and a PC and keeping data sync'd between the two would be easy, or so Apple et al would have me believe. So far I've not only found out that their IP over FireWire, the only feasible way to transfer the large amounts of data I have, is seriously lacking (i.e. I haven't been able to get it to work!) but also that when I try to ease my woes by connecting the Macbook as a FireWire drive in Target Disk Mode, it fails to deliver again. The first time I connected my Macbook to my PC over FireWire in Target Disk Mode, it popped up in My Computer no bother. Alright, so the only partition I could access was my XP partition on the Macbook (thank goodness I have that or I'd be right up the creek!), but I suppose it's to be expected, what with OS X and Windows having different file systems ETCETERAH.
So I'll copy all my media files to the XP partition and then copy them to my XP PC from there, I thought. Every following time I've connected in Target Disk Mode, I've received nothing but a 'removable disk' icon in My Computer which, when clicked, asks me to 'insert media'. WTF, Apple?! So not only can I not have my OS X drive show up in Windows on my PC, but now I can't even have the XP drive show up?! I didn't change anything, I didn't do anything differently, I literally just rebooted OS X to copy the files I wanted from the Apple partition to the XP one. Sorry to come across all 'angry like', it's just not the first, second, or third problem I've encountered since 'switching'. For a company who prides itself on how its products 'just work', it's becoming an eye-opening experience. However, I understand it's probably something I've done incorrectly, rather than the fault of Apple or Microsoft. So I ask you, what am I doing wrong?
I tried to login to my brand new iMac (running Lion 10.7) via Target Disk Mode so as to transfer my data from my old machine. However, the passwords didn't work. This is not a disaster, however, I am now unable to exit Target Disk Mode. I have tried removing RAM and restarting holding down alt+cmd+R+P to reset the PRAM but it just goes straight back to Target Disk Mode. No matter whjat I do it goes back to Target Disk Mode with the padlock and opassword box.
I'm trying to zero the data on an iBook hard drive before selling it. When I connect it to my Powermac via firewire in Target Disk Mode, it shuts down completely about 30 minutes into the proceedure (and yes, the power adapter is connected).
I need to get an iBook G3's system profile (CPU speed, memory, drive config., etc.), but have no video (black screen). Hard drive is ok. Can this be done in Target Disk Mode somehow? I have NO external monitor.
I just attempted to transfer my files from my old powerbook G4 15" to my iMac 20" using Target disk mode. First I tried to use a firewire cable but it didn't work, I think I was using a 400-400 instead of a 800-400. So I used the option to connect to two computers over a shared internet connection using a password. I thought It would automatically transfer my photos and other files but it just transferred these weird extensions for applications and I don't recognize any of it. To make it worse, I tried to open photoshop on my iMac and now its asking for a password! None of the photoshop series would open, it's asking for a serial number. I had photoshop installed before and the guy doesn't live in my state who installed it for me and I don't have any of the original disks. I know Dell does system restore but Macs work differently. I wish I could undo this whole mess, I need photoshop!!
I dont have the original OS disk either, ughh I should have just splurged on a portable hard drive.
I just bought an 800 MHz iMac G4 , and whenever I try to boot into target disk mode it shuts itself down. I am connecting to an intel iMac, and the g4 has no OS installed on it (I am trying to install tiger using my dvd install dvd, the one with the black background and grey x which the G4 won't read). Does anyone know what could be causing this issue? I've already tried reseting the PMU and PRAM.
I'm using a Late 2010 27" i5 iMac and a Late 2009 15" MacBook Pro. I'm going to reformat and reinstall the iMac this weekend but need to grab all my Music/Documents (you know the drill) from it. Last time I did this, I did it over a 100mbps network, needless to say it was absolutely horribly slow. So, today I'm going to pick up a cheap-ish firewire cable and target my laptop as a disk using target disk mode.
Which type of Firewire cable do I need to buy? It's either a 4-pin or 6-pin choice, no 9-pins available at the shop I intend to visit. I have no idea what the difference is between them - hardware is definitely not my game. Both ports look like this (taken from Apple's docs, Firewire 800):
I have a bit of a problem: I cant access my Mac because I lost the password. I recently changed my passwords on several macs, including an old PPC PowerMac G5 from ca 2005. I run 10.5.8 on this and it works flawlessly. I need to use this machine for important work.
So this is what I have tried so far:
1) Tested with all known passwords I have used in the past.
2) Tried to boot from a 10.6 install DVD
3) Tried to boot from just C and later Command C
4) Tried a different install DVD 10.4 (I dont have the original 10.5 DVD)
5) Tried to use T and Target Disk Mode from an iMac with Lion. (disconnected all other FW disks etc.)
6) Tried different Firewire cables
7) Tried different Firewire connections.
It starts obediently and show every sign of Mac-Happiness. But I simply can't get the darn thing to boot. I think it normally should have booted using 10.6?
I have an original MacBook1,1 running Snow Leopard 10.6.8. It will not start up, I have tried everything on this Apple web page , Mac OS X: Gray screen appears during startup, besides an erase and reinstall and I don't know what to do. It won't read the Snow Leopard update disk (My other two Macs do). When I restart In Verbose Mode, it always stops right after 'Airport: RSN handshake complete on en1'. When i started my other Mac in Verbose Mode, after 'Airport: RSN handshake complete on en1', it went straight to the login window. I called Apple support and they said that I need to perform an erase and reinstall but first I need to get an install disk for Mac OS X Tiger 10.4. and get some things off using Target Disk Mode. I do not have a FireWire cable and do not want to have to go and buy one. I have an Ethernet cable and a male - male USB cord. The two other Macs that I have are an iMac7,1 running Snow Leopard 10.6.8, and a MacBook6,1 running Mavericks 10.9.4.
I'm migrating from a MacBook Air (mid 2013) to a new MacBook Pro and both have Thunderbolt. Do I put the MacBook Air in Target Disk Mode? I did at first but the device did not show up in Migration Assistant on the MacBook Pro.
G5 iMac model A1058, 1.8/512mb/160gb.Bought this machine used on e-bay with no operating system, powers on fine, flashing folder with question mark= no operating system. Tried to connect to my i-book in target disk mode via fire wire and the hard drive does not mount on the desktop. Can't find it in disk utilities however i get this in system profiler under firewire.
I'm trying to sort out a problem with a mid-2007 iMac. When trying to start it up normally it would get past the Apple screen, then go onto a blue screen with a cursor and stay there.
I made a bootable Snow Leopard USB drive to try and repair the disk / re-install the OS. Plugged in the USB drive, and tried to boot the iMac into startup manager by holding down the option key. But instead of showing the volumes to launch startup manager, it keeps bringing up a grey screen with the Firewire logo on, which I believe is what happens when launching into Target Disk Mode.
