Macbook Air HDMI adapter not working

I know there are other threads about this but they are a bit outdated. So anyway I bought an hdmi adapter for my macbook air and it was working perfectly for about an hour and a half when suddenly the tv registered "no signal" yet the macbook was still saying it was connected to the tv. I thought it may have been a problem with the tv so I tried on another tv in the house, same result. So then i thought it may be the hdmi so i switched them, same result. So now the only problem could be the adapter or my laptop, does anyone know how I can fix my problem???

Greetings obomb2000,
Thank you for visiting Apple Support Communities.
It sounds like your MacBook Air is not outputting video to your TVs using an HDMI adapter, and you've done a good job of isolating this behavior to either the adapter or laptop.
Here are a few additional steps you can try on your MacBook Air before trying another adapter:
Reset the system
You can reset the Mac's parameter RAM and SMC.

My hdmi adapter not working anymore, no physical damage. Solution?

My hdmi adapter not working anymore, no physical damage. Solution?
Strange is, that i used it several times, it worked fine. Then wothout any reason (like software updete, etc) it just stopped workung, no sync.
I have not changed any parameters of my TV or Beamer.
Hardware:
Ipad 2, Apple Ipad HDMI Adapter, Samsung P2770FH, Optoma HD 65.
Thanks for any help.

I've only used mine a couple of times without any problem, but due to the thinness of the iPad, care has to be taken in inserting the adapter. Slightly wrong angle and it won't go it.
I had a laptop a few years ago where the USB connector failed. I had it replaced under the warantee, The service man told me it was not an uncommom failure on a laptop due to people "torquing" the USB socket while inserting/removing USB items. I have much the same feeling when inserting either the charger cord or my HDMI adapter.
From your description, unless the HDMI adapter failed internally, it sounds like the socket is causing the problem. A few days ago we watch our first movie from the iPad via my ATV2 and "Air Play". Worked great so I don't plan on using the HDMI adapter much at all in the future. Yes, it is a $99 solution, but it works for me. Of course, I already had the ATV2. I doubt if I would buy one just for this abiliity. If nothing else, it seems like a trip to the Apple Genius bar is in order for maybe a replacement unit.
However, with iOS 5 coming out with supposedly total mirroring, it might be worth thinking about getting an ATV2.

HT2090 my macbook air camera is not working

My Macbook Air camera is not working when I try to use photobooth. I have no problem with google hangouts or skype. How can I resolve this problem?

• Restart your Mac. If the problem continues, use the Disk Utility in your Mac's Finder > Go > Utilities folder to repair permissions. Then test the camera again.
• If the your trouble persists,. reinstall OS X Mavericks. Repair permissions again immediately following the restart that completes the reinstall and before testing the camera again.
• Also check your Mac's  > Software Update... or Apple - Support - Downloads for latest Mavericks updates applicable to your Mac model such as OS X Mavericks 10.9.1 Update.

Lightning HDMI Adapter not working with iOS 6.1.2

I have an iPhone 5 which was updated from 6.0.2 to 6.1.2 recently and the Lightning HDMI adapter stopped working altogether for video mirroring; was wondering if anyone has the same situation/any solution for this?
I also have an iPad retina generation which is at 6.1.2, and the Lightning HDMI adapter is not working for it as well.
I've tried replacing HDMI cables, rebooting the iPhone with the cable plugged in, and plugging out/in several times with the charger in/out. The adapter works, cause when I plug it in; I see the top bar flash for a bit... but no dice on the video mirroring to my TV.

I also have this problem and am very unhappy with the way Apple is handling it. Called today to enquire on when the fix will be available and was told it is a software issue that could be fixed if we paid $35.00 to talked through process on the phone. Highly disappointed with Apple, why should it cost me money for them to fix there own issue. Since they are aware of the issue the least they can do it posted the information for the fix online @ no charge.
If I wanted crap service I could have gotten a phone from anyone. Reconsidering purchasing a 5 on next upgrade.

Thunderbolt to HDMI adapter not working

I just purchased a 13 inch macbook air and when I use my thunderbolt to hdmi adapter my Samsung monitor along with my other displays do not recognize my mac. How can I get my monitors/displays to recognize my device? Do I need software to get this working?
I am using an amazon high speed hdmi cable with ethernet. Will that effect my connection?

I finally learned how to get "Detect Displays" to show up. You have to press the Option key while in the Display pane.
Unfotrtunately this does not work. No other displays are detected. Yes, the TV is on and plugged in to my computer.

Macbook Air to LCD not working?

I just bought the new macbook air and i got an mini displayport to hdmi with it; however, when i plug it in, my lcd tv just stays black and sometimes shows visions of my air. When its black, it reads, "invalid format" at the bottom corner. I have tried to reduce the resolutions, but nothing seems to be working. Can anyone help?

Mini display port to HDMI adapter not working

I can not get my MacBook OS X to dispaly on my new Samsung LED TV. I have a mini display port to HDMI adapter (two years old) conneted with an HDMI cable (new) into the HDMI input on the TV. I tried both inputs, tried resetting the TV, plugging, unplugging, restarting, checked all my system preferences...I can not figure it out. I took my cables to a local store, tested the HDMI cable, and it works. Tested the adapter and they had the same problem I have on my Mac. The screen will flash blue when you plug it in, but will not show up in the TV. I think the adapter must be bad, nothing else makes sense???

Hi Kater24,
Apple doesn't make a Mini DisplayPort to HDMI adapter, so the one you've got there is a 3rd party one that's designed to work with the Mini DisplayPort on your Apple computer. The adapter is pretty much plug-n-play, there's no configuration necessary. Plug it into the machine, the HDMI cable from the other end of the adapter into your TV, select the HDMI input on your TV and fire up the computer.
If that's not working it's possibly an issue with the adapter and/or cable to the TV. Any chance you might have access to another TV for troubleshooting purposes?

Mini DisplayPort to HDMI Adapter Not Working

I just got a mini displayport to hdmi adapter that I ordered from dealextreme and it does not work. The adapter had very good reviews and not one review said it didnt work. When I plug in the adapter (with or without a hdmi cable attatched to it) to my macbook, the screen blinks and then goes back to normal. When everything is properly connected the tv shows no input signal (I am on the correct input channel) and the screen doesnt appear in the displayas settings in my macbook pro. I tried to reboot the macbook, shut down and turn on the screen and nothing seemed to work. The detect display option in the system preferences didnt help. I appreciate any help I can get.

MacBook Air (2012 release) not working with projectors

I recently bought four MacBook Airs (all the new 2012 release) and I can not get any of them to work with an LCD projector. I have tried generic and authetic mini display adapters and have tried a few different projectors. All I am able to see when I connect them in a black screen with lines running down.
Interestingly enough, if I connect the MBA to an LCD monitor, it works just fine. Then, once I have connected it to an LCD monitor, I can then connect it to a projector. Also, if I shut down the MBA, plug in the dongle, and restart the computer, I can use the projector immediately.
Additionally, I can not get the projector to work at all when using BootCamp with Windows 7 Professional. It doesn't even see the projector at all not matter what I do.
Does anyone have any suggestions? This is extremely frustrating and Apple is being NO HELP whatsoever.

Guys, I've found a workaround that works for both VGA and HDMI issues, to enable you to use the MBA at clients/concerts/universities/other offices etc. It's not elegant, but it works:
- Turn off MBA completely
- Plug into an HDMI or VGA (perhaps ANY) screen
- Boot up and it'll be perfect; as others have already reported. Thus far these steps are OK for anyone who doesn't need to pre-load content. But for those of us that do...
- Now, here's the trick, u can suspend/sleep the MBA now, THEN unplug the screen, move to your new venue, THEN plug in the ANOTHER screen/projector, and turn back on again and it'll work! Yes, even tho it's a different screen, it'll flash a bit and work things out exactly like we're used to with our older macs.
- ie this enables you to set up an external display at work/home, pre-load all your presentation/content/web pages, close the MBA and go to client/lecture hall, then plug into a projector there without having lost your content.
So, in short, provided the MBA is fooled into thinking it was powered up with a screen connected, it'll work thereafter. PROVIDED it is not given the chance to think otherwise ie don;t unplug screen whilst it is awake.
This SO speaks to a perfectly solvable firmware/driver issue. Probably around power management.

Macbook Air hdmi display not detected

Hi, my 2011 Macbook is not detecting my hdmi display - the screen flashes blue briefly but no display is detected in system preferences or anywhere else.
Any ideas?
+I am using a mini display port to hdmi adapter with the thunderbolt output and I've tried rebooting with display plugged in and my osx is 10.7.5 Lion.
Any help appreciated

Actually I fixed it in the end by getting a new cable, it turned out that for whatever reason my cable was not up to the job.\
I found that a cheap £5 one piece thunderbolt male to hdmi male cable off ebay did the job well and it was my two piece - thunderbolt male to hdmi female attached to a standard HDMI to HDMI cable which caused the problem.
Seems like HDMI can be quite fussy and either it works or it does nothing, no in between.
So my fancy mac now works great with my cheapo alba hdmi tv i paid £25 for and carries both sound and video!
(I don't think I'll go back to windows if I can help it, not after using a mac. Once you've had a mac you realise what a pain in the a*s windows is .. I hardly ever feel like punching my mac )

Hdmi adapter not working after upgrade to iOS 8

My Hdmi adapter (orig. Apple) is not working anymore after upgrade to iOS 8, is there any solution.

The IOS 8 update has nothing to do with the failure of the device. I have a HDMI adapter and it has worked fine through IOS 6, IOS 7 and IOS 8.
You may want to restart your device by holding the home and power button until the Apple logo appears. If the adapter still fails to work you need to determine if the adapter has failed or the port on your device has failed. Best solution is to go to the Apple store with the device and the adapter. If your adapter has failed it may be under warranty if you still have the sales receipt. If the port on your device is bad then the Apple store will be able to provide you with options.

My macbook air camera does not work

I have a macbook air 11" mid 2011   running OSX Yosemite 10.10.1
I need to use the facetime camera, but it says no camera is available.
what I have done (6 hours or research and grief later):
After reading a plethora of forums, I have tried:
Migrated from OSX Mountain Lion to Yosemite.. will definitely fix your problem.   no good...
Installed the latest update... yep...
used the disk Utility repair again just in case...   yep...   still no good.
restarted the computer... yep.       no good...
open a terminal and type         sudo killall VDCAssistant
yep that was a waste of time... its not even on my laptop.
the USB camera is not in the System Information USB Tree. and under camera it says no video capture devices were found.
Found a really helpful UTube video which suggested I Kill off a Parrot thingy...   wasnt even in the devices list...
I have read through the plethora of forums on this problem even further... there are literally thousands of them.
The most popular answer which Apple appears to provide is:    and by the way you keep running into this suggestion...
One of these will fix your problem:
(1) If restarting your Mac doesn't fix the problem,                          (NOPE didnt fix it..)
(2) use Apple's http://support.apple.com/kb/HT2090                      (NOPE no help...   as:
did the use Disk Utility to repair permissions thing..   yep... still no camera...
the USB camera is still not in the System Information USB Tree.
(option 3 applies to me...   cant see the camera in the USB...
no suggestion on how to resolve that ... but there is a (4) so I tried that...
I reset the SMC ...   guess what...   still no camera...
The camera used to work...
...............................................................................     My thought and question of Apple is below ...................................................
I am thinking the port on which the camera communicates is disabled in the new software version, or it is reassigned to something that is in conflict with it. The USB connection is set at the manufacture level to something which is not being detected now.
CAN APPLE PLEASE ADVISE ME WHICH DEFAULT PORT THE CAMERA IS CONNECTED TO AND CONFIRM THAT IT IS NOT DISABLED BY DEFAULT
Please dont tell me its a problem with the camera...   I could probably roll back to the old software, and my system would work just fine...   this has been a total pain in the neck...   and has cost me many hours...
Yes I am going into the Apple store tomorrow... another two hours out of my life... probably to be told its a hardware issue and they need to take it away and charge me money to fix it..     but I will take it there and decline to pay any money.   It is out of warranty and probably not essential to the laptop to use.   It s frustrating that there is no easy fix to this problem despite the plethora of forum articles and posts by thousands of people experiencing the same problem.
There is no way Apple can stick its head in the sand and claim its a hardware issue.
I have tried to look for a built-in USB camera driver for Apple Macbook Air...   good luck with that...   If the old system driver was about, perhaps someone could check the communications ports and work out where this problem actually sits.

There was a final outcome...       Apple determined that the IO card was faulty and they replaced it under warranty..      The camera is working correctly
i cant argue with the results...     The card replacement has reliably fixed the problem.
SO my final recommendation for a solution is
check online to make sure you can get an appointment at your APPLE shop.
Book the appointment so you don't waste 4 hours...
Check that your machine is in warranty.      If not, the repair cost to me was $85 aus...    Still not too bad considering this issue cost me 14 hours of research and a further 8 hours travel time...
BAck up your computer and open the password to protect your regular one. Then...
take it to Apple at the appointed time.     MAKE SURE YOU BACKED UP YOUR MACHINE...
WAit 5 to 10 days based on how busy they are...          If they say your card is faulty, it's hardware and no amount of fiddling about with software is going to fix the problem.        I could have saved 18 + hours..
Replace the IO Card Fixed this issue...       It has not failed since getting the computer back.

Macbook Air internal keyboard not working with windows 7

Hello,
I have a macbook air 1.6ghz (1st gen) . I just installed windows 7 32bit on it and got the latest bootcamp. Everything else works perfect except the keyboard. Anyone have any drivers I could try ? I tried the external ones but I do not have an external keyboard so its not much use. Anyone have the internal driver for it ?
*i have tried bootcamp 2.0, 3.0, 3.1 and 3.2* The keyboard works perfectly on the mac side. I truly believe this is a driver issue because on the device manage under keyboards it has the driver listed as HID and under HID devices one of the keyboard drivers has a yellow exclamation mark.
I have also tried extracting the driver from the Apple drivers folder and running it that way.
Thanks,

Did you install the Windows support software? Did you check in Windows sytem to see if the drivers are working? Check the Boot Camp help documnets http://www.apple.com/support/bootcamp/ and visit the Boot Camp forum https://discussions.apple.com/community/windows_software/boot_camp

Macbook Air thunderbolt ethernet not working after 10.8.3 update

Hi,
Thunderbolt Ethernet for my Macbook Air (11-inch, Mid 2012) stopped working after installing 10.8.3 update. I am unable to conect to my router via thunderbolt Ethernet connection port.
Anyone else having the same issue? Any recommendations?

Unplug your thunderbolt adapter. Restart the router.
Go to your Mac and go to System Preferences >> Network
Use the - button in the lower left corner to delete your Thunderbolt to Ethernet adapter.
Now plug your thunderbolt adapter back in and use the + button to add "Ethernet Thunderbolt" to your list of connections. Move it back up in the order of network preference you want.
Your network access should now be reset.
