Thunderbolt display not working well

I recently upgraded my MacBook Pro to Mavericks and found an issue with using it with my Apple Thunderbolt display. I normally use the Thunderbolt display as my MAIN display with the MacBook Pro closed. Normally, it would wake from sleep reliably but after upgrading to Mavericks, I find that the system "occassionally" (I cannot seem to replicate it reliably) does NOT wake from sleep with the cover closed.
What I have to do is to then open the MBP cover and then key in my password from that screen (not the Thunderbolt display). And even then, the Thunderbolt display remains unusable until I detach the thunderbolt cable and reconnect it again.
Contacted AppleCare yesterday and they suggested that I reset my PRAM as well as rebooting the system whilst clearing some settings etc. Did all of that and the problem is recurring.
Apple - please help !

Thunderbolt display not working on Macbook Pro - previously the display did work

Thunderbolt display not working on Macbook Pro - previously the display did work

I have upgraded ML but when the MBP tries to restart with the upgrade the MBP does not restart so I susapect the ML upgrade is not complete ? When you refer to 10.8.5 supplemental is this a separate upgrade ? When I connect the Thunderbolt to the MBP the Thunderbolt charges my MBP & I can play music from iTunes via the Thunderbolt. It is only the display that is not working on the Thunderbolt

Thunderbolt display not working with bootcamp and windows 7

I am running a late 2013 MBP Retina display with a Thuderbolt monitor. I am running windows 7 on a dual boot partition. I can not get my thunderbolt display to work while working in windows. The screen is currently black. I have attempted to follow the instructions in prior posts regarding this issue with no success. Is there a clear fix to get the monitor to work? Thank you

it has to be plugged into the machine before you power on the machine, it is not hot swapable like on OSX
does the screen work in OSX

External (thunderbolt) display not working at all when in clamshell mode

I have a brand new macbook pro (2014). With a thunderbolt display and external keyboard/mouse attached, I use the computer as a 'desktop' all the time (lid closed). Always worked fine, until I upgraded to Yosemite. Now, either the machine doesn't boot at all, OR (even more strangely), it takes many minutes to boot up, and the animation of fades and also the mouse cursor jump around extremely slowly--the interface is completely unusable and I have to open the display and manually force a shutdown by holding the power button down. Without an external monitor attached, everything seems to work just fine.
Has anyone else experienced this, and has anyone found a work around?
Thank you,
Frustrated with Apple's apparent software quality decline,

Thunderbolt Display not working with Yosemite

Hi all,
After I have updated my mid 2012 Retina Macbook Pro from Mavericks to Yosemite my Thunderbolt Display has stopped working. It makes no difference if I connect the display before startup, or while the macbook is already powered on. It just doesn't power up. The display doesn't show up in System Report (?) while it was actually working on the Yosemite beta 2. I have reset the NVRAM / PRAM and SMC all to no avail. When I connect the thunderbolt cable and power plug the MacBook also doesn't charge.
Does anyone have a solution for this?
Thanks in advance.

By power leak issue I mean something to do with what I just found here https://discussions.apple.com/thread/5276098?tstart=0
I was wondering why my Macbook was a bit tingly to touch. I've since plugged it in with the longer 3 pin lead. No fix to my display issue.

Cs6 and retina display not working well together please help

I just purchased a membership for creative cloud and installed photoshop and illustrator on a new retina display mac book pro. The interfaces look pixelated including the artboards. All updates are current.
I read that adobe latest updates are optimized for retina display. I have no idea what went wrong.
Thanks for your time

Ask in the product forums for specifics. As a start, check the applications using File --> Get Info on teh executables. Verify, that not accidentally half res/ low DPI mode is enabled. Also check in the "About" info that you actualyl have PS 13.1 and AI 11.2, not the base install. Run the updater to obtain those latest free updated versions.

I check all the power cables and and connections and still not he issue. Iv'e tried C-F2 also. has anyone used this devive (AV360) on there own 27" thunderbolt display (not the imac) and gotten it to work? If so I'd appreciate the help.

There are multiple reasons that lead to issue. You should read the troubleshooting guide to get the right solution to solve the issue: iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support

You can't. Theoretically, Thunderbolt devices that only transfer video and audio should work with Mini DisplayPort MacBooks like yours, but it's not the case of the Thunderbolt Display. Its firmware doesn't allow it to be used with non-Thunderbolt Macs, so you can't use the Thunderbolt Display with the Mid 2010 MacBook Pro.
Instead, you have to look for another screen, or you can get an adapter and connect the MacBook Pro to a TV

Caller display not worked since June 2014

On 26/06/14 I reported a fault (VOL-**********) that the caller display function had stopped working following a thunderstorm in the area. According to the fault status this fault is showing as being corrected and closed on 02/07/14 when in fact the fault still exists. I tested the line using the BT test socket with a new BT2000 phone and this displayed ‘incoming call’ therefore my internal wiring is not part of the problem. I have also dialled the test code *#234# to check if the caller display service is available and confirmed that it is. I then tested the new BT2000 phone on the neighbour’s telephone line and this showed the caller ID for incoming calls, as did my other telephone as well; therefore none of the telephone handsets are at fault. Three times BT have informed me that the fault has been fixed and yet I still have no caller display. Reading through the forums it would appear that other people have encountered similar issues and that the problem is at the exchange, “An Openreach engineer discovered that the RS232 burst transferring the CLI number up the line was too weak and he then went down to the exchange to investigate. He then discovered that the fault lay in the ADSL device which lies between the analogue exchange equipment and the outgoing line”.
I’m surprised to see that BT are taking so long to trace a fault in their system last raised 5/8/2014 (VOL012-**********) and that they haven’t sent an engineer to the property or to the exchange to check the problem.
My patience is wearing thin over this problem with my Caller Display not working as it started in mid June. I’m also becoming less enthusiastic about BT and find it harder to recommend them to others.
My last message from BT, tells me that it should be back to normal on the 8 August. However, it is still not working. Their message that my phone should be back to normal now and if it isn’t report this to BT, is ridiculous. If an engineer had investigated what was causing the fault and found it, then he would have fixed it. However, either an engineer has not investigated the fault or BT is not competent in fixing their own service faults and makes these statements with crossed fingers?

An engineer called yesterday and told me that he had been asked to test the line for a voice fault not a Caller Display fault. However, his testing revealed there is no line fault, CLI signal is strong and he was happy that the new BT2000 phone (bought after the lightning strike) is working properly. (This phone had also been tested on a neighbour’s phone line where it displayed the callers number). He also found that this same BT2000 phone on my line was not displaying the Caller’s number (CLI), but couldn’t offer any reason why.
I conjectured with him that these tests must bring the problem down to a corrupted CLI signal which does not allow the phone to understand the phone number being sent.
When the lightning struck the phone line back in June, it blew the telephone connection in the back of the Sky Box with a flash and bang (telephone cable now removed from the Sky box). It shorted the Openreach Faceplate (now replaced) so that the phones and broadband stopped working and it caused the phone to light up and react as it does when a call comes through.
Now isn’t it possible that the lightning also travelled along the copper wire to the green cabinet just outside the house and damaged something there which is corrupting the CLI signal, but which does not not show up when the voice line is tested? If not, then there must be a problem further back in the infrastructure, possibly in the Exchange, that is causing a corrupted signal to be sent to my phone?
He told me that another team would have to investigate the Caller Display fault as he was instructed to look into a voice issue and as a field engineer he was not able to investigate any problem that might be in the Exchange. I don’t know whether this Exchange Team would be able to investigate a problem in the Cabinet if nothing is found in the Exchange or can that only be done by a field engineer? He told me to contact BT again as he’d done all that he had been instructed to do and they would have to instigate a fault team to further investigate the problem.
When all this is considered we have the basic problem that BT are unable to provide me with a Privacy and Caller Display Service that I have been paying for, because of a fault in their infrastructure. How much longer is it going to take before they correct the problem that’s been going on since June 2014?

Thunderbolt ethernet not working when computer wake up from sleep.

thunderbolt ethernet not working when computer wake up from sleep.
it will not happen in Mountain loin.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.
Link to the article: http://www.fastcompany.com/magazine/06/writestuff.html

Apple thunderbolt display can work with a macbook pro 2009?

Apple thunderbolt display can work with a macbook pro 2009 (mini display port? The image passes through the mini display port to the monitor, but the connections (Firewire, USB, ethernet) do not work. Can you confirm?

I'd love to get confirmation if this is the case too. I was all ready to buy the new iMac until I found I couldn't use it as an external monitor for my DisplayPort-based MacBook Pro. And then I was all ready to buy the new display.
I really hope Apple hasn't restricted this to purely Thunderbolt-equipped Macs. I know I'll end up upgrading my MacBook at some point but I can't do so just yet, and this means I'll have to go for some third-party display, camera, speakers etc for the new Mac Mini which is crazy.

Hi my name is Silvana Pires,I purchased an I Phone 4 S Model A 1387 EMC 2430 SCC.ID DCG E
2430 AIC.579 C-E 243 A in California one year ago,Unfortunately its Not working well the screen is getting black,and the phone is in good shape I can prove it,the Apple support in Brazil doenst work like in USA.
I look forward to your reply and a resolution of this problem.
Thank you very much!!!

You are welcome. I'm glad you got it back up.
(1) You say you did the symbolic link. I will assume this is set correctly; it's very important that it is.
(2) I don't know what you mean by "Been feeding the [email protected] for several weeks now, 700 emails each day at least." After the initial training period, SpamAssassin doesn't learn from mail it has already processed correctly. At this point, you only need to teach SpamAssassin when it is wrong. [email protected] should only be getting spam that is being passed as clean. Likewise, [email protected] should only be getting legitimate mail that is being flagged as junk. You are redirecting mail to both [email protected] and [email protected] ... right? SpamAssassin needs both.
(3) Next, as I said before, you need to implement those "Frontline spam defense for Mac OS X Server." Once you have that done and issue "postfix reload" you can look at your SMTP log in Server Admin and watch as Postfix blocks one piece of junk mail after another. It's kind of cool.
(4) Add some SARE rules:
Visit http://www.rulesemporium.com/rules.htm and download the following rules:
70sareadult.cf
70saregenlsubj0.cf
70sareheader0.cf
70sarehtml0.cf
70sareobfu0.cf
70sareoem.cf
70sarespoof.cf
70sarestocks.cf
70sareunsub.cf
72sare_redirectpost
Visit http://www.rulesemporium.com/other-rules.htm and download the following rules:
backhair.cf
bogus-virus-warnings.cf
chickenpox.cf
weeds.cf
Copy these rules to /etc/mail/spamassassin/
Then stop and restart mail services.
There are other things you can do, and you'll find differing opinions about such things. In general, I think implementing the "Frontline spam defense for Mac OS X Server" and adding the SARE rules will help a lot. Good luck!
