Won't start with thunderbolt display attached

Almost new 3.5 Ghz Intel Core i7 iMac 2014 SSD only, 32GB disk running 10.9.4. Absolutely will not start up from shutdown state with an additional 27" Thunderbolt display attached. Unplug the display, boots fine. Then plug in the display, all works peachy. Sleep is also broken and hangs on restart, except if you only sleep the displays, not the CPU then it always wakes up fine. This is pathetic, very Windows-like.
Suggestions?

10.9.3 and 10.9.4 have known issues with displays attached via Thunderbolt (for example see here Second display problem with 10.9.4 and 10.9.4 - Thunderbolt display for 6630M (Mini mid-2011) still broken ).

IMac won't start with Thunderbolt Display connected after firmware update

After updating my thunderbolt display firmware to version 1.2 this morning via the App Store, my mid-2014 iMac won't start up with the external display connected. I can get the iMac to start up only by disconnecting the display's thunderbolt connector. After the iMac comes up, I can reconnect the display and everything appears to function normally. I've tried several restarts and the iMac won't start up with the display connected. Anyone else experience this?

Major Issues with Thunderbolt Display in Yosemite

I have a MacBook Pro (Retina, 13-inch, Early 2013). I'm having issues with thunderbolt display connectivity despite recent Thunderbolt Firmware update. The sleep wake function is not working and display with shut off sporadically.
MacBookPro10,2 Processor Name: Intel Core i7 Processor Speed: 3 GHz Number of Processors: 1 Total Number of Cores: 2 L2 Cache (per Core): 256 KB L3 Cache: 4 MB Memory: 8 GB

Same problem here. I was so excited to see a firmware update this morning for my mac pro, and sure enough as i sat here, the display went black again.

OS X 10.7.2.2 issues with Thunderbolt Display

Help! With Thunderbolt display, Mac-mini and OS X 10.7.2.2 I get a blank screen when mini reawakens from sleep. Moving the cursor around like a paint brush reveals a portion of the underlying log-in screen. Once I uncover my user icon and log-in, my desktop will appear and function normally!!!
IS this caused by (1) the Thunderbolt display, (2) the latest Lion update or a combination of both ? I experienced no problems with older display and Lion 10.7 !!
Any solutions/recommendations?

Hello Drew,
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

SatelliteU300 Won't start with AC power connected and fully charged battery

I just bought a U300-13U. It works great when battery is charging and AC is connected. However if left to charge up fully it won't start with AC connected. Unpluging the power or removing the battery and running on AC makes it work fine. Is this a 'feature' to stop overcharging or overheating the battery, or just a problem with this machine. I want to run with AC and battery both connected all the time as I have done with all my other laptops.
Any help appreciated.

Hello Andy
Friend of mine has this small U300 and everything work well. I have had it few weeks ago to test WXp installation and it works perfectly.
Please test it again very carefully and if the same happen again I recommend you to contact Authorized service partner in your country. Let them check your notebook. I must be honest and say that described issue sounds strange to me and please do not wait too long. Contact service as soon as possible.
Bye and good luck!

My PC won't start with only one push of the start button.

hi guys my pc won't start with only one push of the start button. It takes me 1 to 10 pushes for it to start. I encountered this main bios error once when my pc started but it fixed on its own. What could be the problem?

Hi
The problem can be fixed by running a latest BIOS Update on your unit or if it is a mechanical issue it could be the power button itself.. you can call HP tech support if the notebook is still in warranty.. they'll be able to help you.
Hope this helps.

I have a Thunderbolt iMac 27" with a Thunderbolt Display attached. I would like to use the iMac and Thunderbolt display in Target Display Mode for my new Thunderbolt MacBook Pro. So far, it seems I can only use the iMac screen itself. How do I do this?

When I press the Command + F2, the iMac screen becomes a secondary for the MacBook Pro, and the Thunderbolt Display becomes the primary screen for the iMac. I was hoping that both screens would become secondaries for the MacBook Pro. Does anyone know how I should proceed? I have tried to connect the Thunderbolt display directly to the MacBook Pro, and the iMac to the Thunderbolt Display via the separate Thunderbolt cable, but there was no difference. And since the MacBook Pro only has the one Thunderbolt port, I'm not sure how to proceed.

Yes, eww, the language definitely states two thunderbolt displays, but I can understand the confusion and was siding with how they could make the mistake to think it would work like they want it to. My appologies for not being clear on that point, but I think you make it clear that the language in the ad says nothing about an imac.
Having said that all the language about TB would suggest that this would be possible. http://www.apple.com/thunderbolt/
High performance on display.
Thunderbolt I/O technology provides native support for the Apple Thunderbolt Display and Mini DisplayPort displays. It also supports DisplayPort, DVI, HDMI, and VGA displays through the use of existing adapters. So you can connect your Apple LED Cinema Display or other display, along with multiple high-speed devices, all from a single port.

Thunderbolt Display attached hard drive

I hope this isn't a completely stupid question...I just haven't been to the Apple Store to ask nor have I been able to find an documentation to confirm or refute this issue.
Will a hard drive connected to the Thunderbolt Display that is hard-wired to a network via the Gigabit port be available as a network drive even when my Macbook Pro is not attached to the display? Will they be similar to a network attached storage device or do they need a Mac to be attached in order to mount them?
Thanks

Bought a TB display to use with my 2011 mbp last night. Hate that it doesn't have a power button.
Really hate that the usb implementation seems quite broken. I spend 95% of my time in Windows, and while the display functions, usb doesn't really. The apple usb keyboard i bought sticks, and my dell mouse hangs frequently. both are plugged into the display, but they work fine when plugged into the laptop directly. I also have a jabra usb headset plugged into the display.
I have noticed I can worsen the situation by actually using the display hardware. If I start a call using the headset, the keyboard and mouse become even worse. If I start using the facetime hd camera on the display, they become horribly erratic.
Apple definitely has some work to do. They are billing this is a docking solution and it is completely unusable as such right now.

Always mirrors (won't start with extended desktop)

Since upgrading to leopard, I have the following problem: Whenever I plug my MacBook into a particular external monitor (a projector with 800 X 600 resolution), it automatically goes into mirroring mode - even if I last used it in extended desktop mode. I can then turn off mirroring, but all my windows have shrunk (to fit 800 x 600) and have moved. I leave mirroring off when I unplug - but then the next time I plug in, the same thing happens. I want it to start in extended desktop mode, and not automatically enter into mirroring mode. Any ideas?

MBP changing color when thunderbolt display attached

So I have the last gen 17" mbp running 10.8.2. the color on the display looks great except when I attach my new thudnerbolt dislpay. The color temp of the MBP display goes really cool (blue) when the thunderbolt display is attached. Whenever I unplug the display, it goes back to normal. Anyone else seen this or have any idea what is going on?
Thanks,
Scott

Macbook air with thunderbolt display - windows stuck on air's display

I have a Macbook Air and a Thunderbolt display. When I use the Air without the Display attached, the windows gather on the Air's display. When I return to the setup with the Display included, some of the windows remain on the Air's screen making it impossible to get to them without opening the Air and manually moving the windows around. The Air is tucked under the display, and opening it to move the windows back to the Thunderbolt Display is a PITA.
Despite the lid being closed (and never having been opened after waking from sleep/connecting the Thunderbolt Display) the Displays control panel still sees that display as active.
I cannot find a way of moving the windows back to the main screen unless I'm lucky enough to grab the right spot to move the windows to the larger display.
1. How do I get the Mac to recognize the Air's lid is closed, and to disable the built in display?
2. If that's not possible, how do I use Mission Control (where I can see the windows) to get the windows moved to the right screen?

I have no idea where that dirt came from. I really have no clue what it is, and it won't go away by blowing in it. I will contact local authorized store (there is no Apple stores in Croatia) but I highly doubt they'll be able to do anything without taking the laptop apart. Although I highly doubt it could it be rust from cleaning my MBP? I always put a couple drops of water on cloth I clean my macbook casing with. I have no idea if I am going to be able to do anything at all because the gap is really small, pin couldn't get to that dirt. I don't know what that could be, I never eat or drink close to my mac. Just my luck. What's Q Tip? Never heard of it since I live in Croatia

GPU Panic with Thunderbolt Display after upgrading to 10.9.3

Hi everybody! I have a MacBook Pro Retina Mid 2012 and use it with a Thunderbolt Display 27". After upgrading to 10.9.3, a GPU Panic error started annoying me. All displays (thunderbolt and mac) go black and I have to hold down the power button to force the shutdown and then power on.
Sometimes, I connect the display and it works for some days. Sometimes, it crashes just when I connect the thunderbolt display. It's just not what we expect from such premium product.
I've read the posts similar to this, did a PRAM reset, etc, but none of this worked for me. Any ideas?
This is the last crash log I had today. Please anybody help me! Thanks.

Won't boot with external display connected

My MacBook Pro (circa 1997) won't boot with the external display connected. I can connect the external display (20in flat planel) after it has started, and it works just fine.
I have tried two different DVI cables (one of which I think is a DVI-A cable) and the DVI-to-VGA cable. The result is the same.
During the boot phase I get the tone, the apple logo and the progress wheel. After 30 seconds to one minute those disappear to be replaced by an empty blue screen.

In case anyone wonders, my "solution" was to change to a WB Elements Desktop 3TB (only USB 2.0 is currently available for this model). I miss the speed of USB 3.0, but it's much nicer to not have to remember to unplug and plug in the hard drive each time I boot.
Still hoping to see a proper solution to this (since I don't have the WB My Book anymore, I can't test adaher's suggestion).

HT204154 My macbook with thunderbolt display without power supply stops working on battery mode, is that normal?

I use a 27" Thunderbolt display on my macbook pro. If I disconnect the power supply from the mac, the monitor stops working.
Is that normal or do I have to make some changes on the setup ?
Thanks

Greetings koningsvaren,
Welcome to the Apple Support Communities!
I understand that you connect your MacBook Pro to an external Thunderbolt display and everything works as it should while connected to power, but once power is removed from the MacBook Pro, the second display no longer functions. It sounds like you may be using this configuration with your MacBook Pro closed, otherwise known as closed-clamshell mode. In order to use a second display with your Mac portable in closed-clamshell mode, the Mac portable must be connected to power. Please refer to the attached article for more information. If this is not the case, please let me know.
