I'm using 2 IMac 27' and one is simply used as an external display. When I wake up the computer from sleep, it works on the main monitor, however the external display still has a black screen. I have to unplug the external monitor to get it to wake up. I tried unplugging thunderbolt and replugging it in which worked the first time, but same issue again not waking up.

I have a new 27" iMac retina display. Is there any way to use it as an external display (since it does not support Target Display Mode)?

I want to buy the 27" iMac - but only if I can use it as external monitor for my Lenovo laptop when working from home. A the Apple store in London they said that this is possible with a Belkin converter from hdmi to mini display port (with a USB power caple to turn it into an active signal). The laptop also has a displayport.

I am running a new 27" iMac and a MBP 17", both running 10.7.4. Both have Thunderbolt ports. I bought a thunderbolt cable and wish to use the iMac as an external screen for the MBP - Target Display Mode. I have connected both togther via the thunderbolt cable and used Cmd-F2, but nothing. System Information identifies the Thunderbolt ports (2 on the iMac) and nots No Devices Connected.Â

Sometimes it kicks right up to the external monitor but the majority of the time it cant reconnect to the monitor. It just turns blue then off then blue likes its trying to figure out what to do eventually it says out of range. I then have to unplug the external monitor, wake up my mac with the screen open reconnect the monitor wait for it to pick up and then close it again and wah laaa it works.

I have a new 3.4 GHz Thunderbolt iMac and can't get Thunderbolt Target Display Mode to work with my current-model 13" MacBook Air or the current model 15" MacBook Pro furnished to me by my employer. Cmd-F2 just creates a beeping sound. I tried three different Thunderbolt cables. (They are not Mini DisplayPort cables. I have one of those from a previous model of iMac and it both looks different from the Thunderbolt cables and System Information doesn't show any change when I try to patch the computers together using it.)
All machines are fully updated to MacOS X 10.7.4 with all firmware updates applied. System Information shows that all are equipped with Thunderbolt interfaces; the Console app shows the kernel message indicating when the Thunderbolt devices are plugged in and removed; all three machines work in Thunderbolt Target Disk mode in both directions with all three cables with both Thunderbolt interfaces on the iMac.
Target Display Mode display mode won't work with my imac 21.5" mid 2011. I tried both commands cmd+f2 and cmd+fn+f2 but nothing! I'm using thunderbolt cable to connect my macbook air. Why I'm can't use my imac as external monitor?

Any chance of a Target Display Mode as seen in the new iMac for the MBP? Is this a hardware or software thing?
View 7 Replies View RelatedSo I have a Mac mini set up with Windows 7 only and then I have that connected to a 27" iMac with the miniDP cable.
At first, during installation, I have no issues; Windows is installed and drivers are done... reboot.
I start seeing artifacts, especially in dark areas (little sparkling pixels of colors--kind of like white noise except it's not everywhere and this is in color), also every few seconds the screen would flicker, and occasionally the screen would change to where the bottom of the be on top (hard to explain, but imagine a movie where the frame isn't centered and you can see the bottom of the previous frame and the top of the current one).
I figured it was an issue with the iMac, so I switched back to the iMac and there are no issues. I switch back to the Mac mini and screen is still messed up.
I have a 21.5' iMac (Mid 2011) and a 27' iMac (late 2012) that I would love be able to use Target Display Mode. Unfortunately I have tried everything I could think of to get it to work. Here is a list of things that I have tried but have been unsuccessful at enable TDM:Â
1.) Completely restored Mac OS X 10.9.5 on the 21.5' iMac. Setting this machine up as new since it will be my external display.
2.) No firmware password enabled
3.) Reset PRAM on both machines
4.) Connected an Apple Keyboard w/ numeric keypad to the 21.5' iMac.
5.) Pressed CMD+F2 to enable TDM (no luck)
6.) Tried to enable 27' iMac as external display Â
Repeated same process with an 13in Macbook Air (Mid 2011) and got the same result. TDM will not work.Â
So I did some extra troubleshooting to try to target why TDM won't work.
I put my 21.5' iMac in target disk mode and connected it via thunderbolt with my 27' iMac but it doesn't see the 21.5' iMac while in target disk mode. I also tried the same process with my 13' MBA and I don't see the 21.5' iMac while in target disk mode.

I use a Belkin AV360 so I can play my Xbox 360 on my new 27" iMac using target display mode. it has been working flawlessly since I got the AV360 until today where I haven't been able to get target display mode to work.
I've checked it is not the Xbox 360 being the problem tested it on my housemates TV. am also pretty sure it's not the Belkin AV360 itself because in system profiler under USB devices it says the "AV360 miniDP Converter" is pluged in and say same in Windows 7 bootcamp under device manager. I also tried my laptop which has a HDMI out on it.
my laptop says there is a "Belkin dongle" plugged in, I set the laptop to use the Belkin dongle at a external display and still I can't get target display mode to work.
Normally when I turn my Xbox on it automatically goes into target display mode or I can press cmd + F2 so to switch between iMac and Xbox. I have also tested my housemates Xbox in my setup and still the same problem.
I am thinking about using my iMac as an external display for my Dell Laptop listed in my sig. Most of the time at home I can work on my iMac, but occasionally I use windows, and I have the dell for that. According to Apple:
"On the 27-inch iMac, the same port offers input, too. So you can connect any external source that has DisplayPort output � including a MacBook or MacBook Pro � and use your iMac as a display."
I just saw this new thing TDM, and I'm really interested, meaning I can hook up my MacBook to it and all sorts of other stuff. I've been trying to find more info on apple's site and google but there's nothing much mentioned.
Can anyone tell me what kind of cable is required? Will it eventually need like 10 adapter heads?
Only the 27" iMac supports this feature. I'm seeing a lot of incorrect info thrown around the forums.

After installing the iMac's Target Display Update 1.0 and 10.6.4, I'm no longer able to connect the MBP to my iMac. When I plug in my mini displayport cable, the iMac's screen goes black for a few seconds, then the MBP's screen flashes blue for a second or two, and then back to normal, and finally, the iMac's screen goes blue for 5 seconds or so, and then back to the desktop.

I was told that the new 5k imac can support one external 4k display via thunderbolt, but the 5k imac cannot itself be rotated into portrait mode (on a vesa mount for example). If I connect an external 4k display via thunderbolt to the new 5k imac, can the external display be rotated into portrait mode so I can have 3840 pixels vertically on the 4k display?

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 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.Â
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'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.Â
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.

Can you do a target disc mode through a usb male to male cable? I want to Sync exactly my work files from my iMac to the MBP for when I go away. The best way I've found to do that is to use a free app called SyncTwoFolders. Â
It means you can copy your work between two computers go away with one and work for a few months come back and sync it with the other and vice versa. To do this you need to connect two computers. My iMac has Firewire and USB. The MBP has USB and Thunderbolt. USB to USB doesn't seem to work.Â
What cable should I buy to do this? Firewire to Thunderbolt? Firewire to USB? USB to Thunderbolt?

I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.
We have some new Intel iMacs and have transferred some information from our previous G4 PM (one MDD and one Quicksilver) to the new iMacs. For some reason the G4's will now not boot up and kernal panic on the gray Apple boot screen. This has happened to all the G4's we have in our office. They are running OSX 10.2.8 and the iMacs are running OSX 10.4.4. We can still mount the drives from the G4's using FireWire Target Disk mode.
I have tried zapping the PRAM etc but they still wont boot. I have also tried running the OSX 10.2 Installer disks to try and reinstall OSX on the G4's but the installer cannot see the drives?
I tried running the disk utility. It finds the hard drive but wont let me verify/repair permissions (the option is grayed out). It will only let me verify/repair the disk, but it finds no errors. The installer cannot find the disk at all.
We have more than one hard drive in the G4's and the target disk mode will only mount the system drive, it doesnt see the others, so we cannot retrieve out information. Whats going on. Never had this problem before.
Anyone have any idea what is wrong. Never had this problem before using the FireWire transfer.
This started recently and is quite annoying. Like the title says, if I put my computer to sleep via apple menu/sleep while it is attached to my external monitor the computer will not "wake up". When I try to wake up the computer the sleep indicator stops pulsing and I can hear the hard drive start spinning. As a result I must force shut down the computer by holding the power button. The computer is fully charged so it is not a low battery issue. The external monitor is an 20" Apple Cinema Display, it is attached via Apple's DVI connector. Â
Unplugging the monitor dongle and replugging it in do not work. Pressing any assortment of keys does not bring the display back up. Â
I've tried resetting PRAM, disk permissions, and verifying the disk.Â
