MacBook Pro :: Won't Detect New Thunderbolt Display 27 Inch
Aug 25, 2014
I have a Macbook Pro mid 2009 running Mavericks. I have an old 23" Cinema Display that uses a big chunky adaptor (ADC?) with a dual USB and Thunderbolt cable and it works well with it, however, I just bought a new Thunderbolt 27" display and it just won't detect it. I also notice that a lacie drive in the same Thunderbolt slot won't show up either. The old Cinema Display does still work however using that same slot so it's not actually dead. Puzzled! Â
I know this MBP is probably one of the first generation to have Thunderbolt but I've never used it for anything other than the old Cinema Display adaptor.Â

I have a Mac Book Pro, my partner a Mac Book Air. I bought a thunderbolt to HDMI cable from eBay so my partner could plug her Air into the TV. When the cable arrived, it would not detect our LG TV from either computer. So a bit of playing around and this is what I found. Â I plugged the cable from my MBP direct to the HDMI port on the TV and nothing, no signal detected. I also tried from the MBP to the HDMI port on the amplifier of the surround sound system and again nothing.However, if I plug the cable from my MBP directly to the TV HDMI and select that corresponding HDMI port on the TV initially still nothing.
But if I then plug a normal hdmi-to-hdmi cable from my amplifier to the Mac Pro's HDMI port, suddenly the thunderbolt cable works and the Display Preferences sees the LGTV. I checked that the correct hdmi port was selected on the TV for the direct connection and I could even turn off my amplifier to make sure that I was not seeing the wrong signal and it still worked as long as the hdmi-to-hdmi was still connected at both ends. However, if I then unplug the HDMI cable from MBP or the amp, the thunderbolt port stops working as well and the TV displays "no signal detected".
It seems that there needs to be either a base signal or an earthing through the MacBook Pro's HDMI port for it to switch into an external monitor mode that will detect a thunderbolt to HDMI connection. This is sort of fine for my MBP as I had nothing working before but it seems a bit pointless having the HDMI cable plugged in as well as I might as well just use this in the first place. However, as my partner's Air only has a thunderbolt port and no HDMI port it still doesn't work with her MAC.

I'm using a 13 inches mid-2011 macbook air with OS X 10.7.4 on 12 June, I found the update of Thunderbolt 1.2 in the system update center and I patched it. Luckliy, this patch didn't kill my kernel as it did to many other machines. But I'm still a bit worried when I learned that this updates messed up a lot of users' machines. Now applle announces the newer version of thunderbolt 1.2.1 to correct what was wrong. But no matter how hard I try to check system updates, I don't have it. I know I could try to download it on the website, but is there any valid reason that I don't get this patch? Will install in creating new problems?

I use MBP (late 2011). I find the hunderbolt port to be similar to the mini-display port of older mac. I wish to have another display, but not ready to spend $999 over a thunderbolt display from mac. So would like to know if a Mini-diaplay port converter from apple would help me connect a exernal display via the thunderbolt port?

My MacBook Pro (15-inch i7 Early 2011) won't detect an external display using an apple mini displayport -> VGA connector using 10.7.3.All cables and the monitor are fine because my white macbook detects the LG monitor without any problem.I have read and tried every 'sollution' suggested on the internet, but all fail. Since my MBPro can't even detect my Sony LCD TV (my white macbook does) i suspect it's a firmware/hardware issue.I want to buy a thunderbolt display, but am not sure if i can spend all this money when even this simple VGA connection won't work.

I have a 2011 MBP (thunderbolt) that I've had for about a year now. I use it daily at work, with an external LCD monitor connected with a mini-dvi -> DVI, no problem, except for the occasional need to restart when first connected.
However, at home I have an AOC Razor 24" monitor that until recently was connected to my home PC via HDMI, working just fine. However, my PC died and now I would very much like to be able to use this monitor at home until such a time when I get around to finding a desktop replacement. My MacBook Pro, however, has completely different ideas it seems... It completely refuses to recognise the monitor. I don't get the blue "flash" and it doesn't show up int eh display panel at all, not "sleeping" or otherwise, it simply looks as if it's not there.
Having trawled the forums, I've done the Jan/Feb firmware update, I've tried two different HDMI converters (One the Moshi from my local Apple retailer, the other a no-name brand converter, which works fine elsewhere), I've even tried a mini-dvi -> DVI -> HDMI converter (I know, I didn't expect it to work, but when you're at then end of your wits, you're at the end of your wits ). I've gone through three HDMI cables and tried an assortment of "black magic" solutions found on the net, with the adapter half-way plugged in, resetting the PROM, closing/opening the lid, running gfxCardStatus ( just in case it did something ) and checking the monitor elsewhere.
The only thing I haven't done (that I can think of) is swap the actual MBP,however, as mentioned, I use an external DVI monitor every day, so it doesn't seem likely that that's where the problem is... I'm guessing it's got to do with how the monitor handles HDMI or some such thing but I don't seem to be able to find much of a comment from anyone else on the net, so here I am... I considered sacrificing a goat at full moon, but I'm not entirely convinced that'll do much either and I upgraded to Lion as I saw a throwaway comment somewhere from someone, indicating that that might or might not have helped them with a slightly similar problem... So this problem now spans 10.6 AND 10.7...Â

I have a macbook with leopard osx and use it frequently for presentations and so on. I have connected it to several monitors and projectors a hundred times and it has worked fine since last night.
Last night, I have connected my mac to a monitor with vga cable but it did not detect it and instead a constantly flickering blue screen came up and never went. I am sure the cables are fine.

I just received a new Macbook Pro (2012, retina display) and a 27" Thunderbolt display. I am having problems getting the notebook to turn on the display. I called Apple (Monday) and they had me reset the SMC and then the PRAM. After this the monitor was recognized and worked fine for the rest of the evening. However, when I turned things on yesterday evening the monitor would not turn on, and resetting the SMC and PRAM (multiple times) has no effect.

My Macbook Pro (15 in 2 GHz core i7) absolutely crawls when I plug in the thunderbolt display. I'm running on snow leopard with 4 gigs of memory. Ive made all the neccesary updates. I plug in the screen and close my laptop and the computer gets unbearably slow. Once I open it up it gets way better and when I unplug the display it goes back to 100% speed. Ive called apple and they cant figure it out. Ive taken it to the apple store and they tell me they cant figure it out.

I have a new 2012 Macbook pro 17 and a 27 inch thunderbolt display.Â
The Macbook was working great. Then I connected it to the thunderbolt display and did clamshell mode. That worked well too. But.. then I powered down the macbook, disconnected the thunderbolt dislplay and tried to boot back up again. The mac book powers on, the back light comes on, I hear the chime then that is it. The back light stays on nothing else happens. Resetting the PRAM can not be done. Any of the boot options are ignored. It is like the keyboard is non resposive. I tried all the reset and boot combinations available but nothing works. Â
The light on the front of the macbook comes on then goes dim. The apple logo on the lid stays lit, and if I close the lid, the apple logo goes dim and the light on the front lights up. Weird, it is almost like it goes to sleep when it turns on. I tried conntecting the thunderbolt again but no joy. I am really disappointed. This is less than a month old and its already going in for repair. It should be replaced. Â

So my macbook pro (2011 late model) has the fan speed of around 2000 rpm during the normal use.Â
Then, when I connect it with a Thunderbolt display (with an ethernet cable for internet), the fan speed is increased to 3200-4000 rpm suddenly.Â
I just don't understand how connecting to a display alone will increase the need for cooling that significantly.Â

I recently purchased a Macbook Pro and a Thunderbolt display. It appears when I plug my Macbook Pro in with the power adapter directly to an outlet, it charges fine. However, if I use the charger on my Thunderbolt display cable, the status reads "Not Charging"... sometimes. Sometimes it works. Sometimes it appears to toggle between charging and not charging. Is this a known issue with Macbook and Thunderbolt? I assume it should always be charging if it's plugged in and the battery is low.Â

I've been having a nightmare getting WIndows 7 to work properly with the second display on my MBP 15" (Early 2011) i7.Â
I'm currently running Lion 10.7.4 which works fine on both the internal laptop panel and the external AOC monitor through a Thunderbolt -> VGA Apple Adapter.Â
Bootcamp installed Windows 7-x64 with no issues, but when it came to trying to get the second monitor fired up it wouldnt.Â
I noticed when I installed WIndows and when I boot into it, that the screens mirror one another, I take it this is the Intel GPU running. I'll explain why in a bit.Â
1) I updated all the bootcamp files through Apple Update, no change
2) WHen I extend the displays, Windows sees the display, make and model without any issues, but it gets no signal
3) I then manually removed the ATI Radeon HD6xxx drivers manually, rebooted and both displays mirrored again throught a 'standard VGA adapter', this is why I assume this is the Intel kicking in.
4) I downloaded the latest ATI Drivers... ATI Mac Drivers -> Bootcamp -> Macbook Pro
5) Rebooted, and still stuck at step one now...Â

Mac OS X 10.8.5 crashes after I disconnect the thunderbolt display. Â
I normally work in the studio with my macbook connected to an external display.
When I go to use it without the thunderbolt display it crashes - 4 times in one day.Â
I've checked my log files and I have a list of panic reports. each of the reports refer to the graphics control.

I have a 3 inch vertical band in the middle of my 26" thunderbolt display which is connected to a 6 month old 15" Macbook pro running OS 10.9.3. This band randomly flickers on and off and shows a burned-in image of the previous window. It may disappear for as much as a few weeks but then return for minutes or hours. I tried restarting with all peripherals disconnected (hard discs, Bamboo graphics pad etc) with no effect.

I have a 17-inch MacBook Pro and a 27 inch Thunderbolt display. I've been using both for about 2 years now. On occasion, the display disconnects for no obvious reason. Unplugging it from my MacBook Pro and replugging it in seems to solve the problem, but its been happening more frequently lately.Â

I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.
