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 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

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.

My macbook air bluetooth does not pair with a bluetooth speakers!

Recently I bought this http://www.amazon.co.uk/gp/product/B00MPT631O?psc=1&redirect=true&ref_=oh_aui_de tailpage_o01_s00 speakers it pairs with my Iphone 5 perfectly, but when I try to connected to my macbook air, it does not work for me it shows the following window, which cannot get connected to the speakers, thanks in advance for any help

While it appears that the Mac is discoverable, since it is not seeing the speakers, you may need to check the documentation that came with the speakers to see if they are in discovery/pairing mode, and how to get them into that mode. Then try and pair them.

Suddenly my MacBook Air password does not work to open my session. I haven't changed it so need help, thanks!

The password I usually use to open my MacBook Air suddenly does not work. I haven't changed it so don't know what to do next. Will appreciate your help!

MBP CD2 DVI to VGA not working with projector

I am having issues getting the MBP to recognize a DELL 2300 projector through a DVI to VGA apple cable.
A few months ago there were posts about this, but no solutions. The problem seems to be with the 'INTEL' side of things, as the same projector with the same DVI to VGA apple cable works on an older G4 tower running 10.4.9. The projector also works on an old G4 iBook with it's version of a VGA adapter. To make things more confusing, a DVI to Video apple cable works with the DELL 2300 on my new MBP C2D-but produces a terrible quality picture. Mysteriously, my previous 1st generation MBP CD worked with the DELL 2300 via a DVI to VGA apple cable (but I'm not sure which OS was out at the time 10.4.8?)
My new MBP CD2 definately recognizes the projector through the DVI to VGA adapter, but the projector doesn't recognize the video signal from the computer. It is DEFINATELY the MBP (or universal drivers), as I have checked the DVI to VGA dongle (works), have checked the projector (works with an ibook running 10.4.8 OSX with VGA dongle), have changed resolution settings before and after connecting, have restarted computer, have tested various orders of connecting the projector and cables. STINK! (I also have TWO DVI to VGA adapters, so it is not a bad adapter). I have also played with exchanging various plist files from older universal versions of 10.4.8 that worked with the projector-no help.
As I stated, the projector will work (in horrible quality) with a DVI to Video dongle. Why it will not work with the DVI to VGA dongle is a mystery and annoying I would hope that a newer MBP CD2 would be plug and play (like my previous MBP CD and an old G4 tower and an old iBook G4...but no).
Any ideas, any help, any answers?

Here are the actors in our play today
1. MacBookPro A. (my system a CD2 2.16 with OSX 10.4.9)
2. MacBookPro B. (my friends system a CD2 2.16 with OSX 10.4.9)
3. an iBook (my friends 1.07 GHz G4 with 10.4.8 and a VGA adapter)
4. DELL 2300 MP projector
Plugged in DVI to VGA adapter to the virgin MacBookPro B (never had the projector plugged into it before) Dell projector shows that it recognizes an analog RGB 800X600 signal from MBP B. It projects a beautiful desktop. All is well for a moment.
In Display preferences we see for the MBP B
Color LCD, Display: 800X600 stretched, Colors: Millions, Refresh Rate: N/A
VGA Display
Now, I unplug the DVI to VGA adapter and naturally MBP B readjusts to it's native resolution. Great.
Now I immediately plug back in the DVI to VGA adapter. The computer and the projector searches for signal with none found, while the computer shows no attempt at an automatic readjustment as above (800X600 stretched).
I try the 'detect display' option. It causes computer to stall for a second (as it searches) but it does not detect projector and does not readjust it's own resolution to 800X600 stretched as it did initially. F7 key does nothing.
This is a problem!
So, I shut down the projector. I unplug the projector's power source and waited 20 seconds. plugged it back in, started projector back up.
I shut down/restarted the MBP B.
I plug back in the DVI to VGA adapter into the MBP B. The MBP B screen flashes to all blue, but does not automatically change to 800X600 stretched (remains at native resolution and does not recognize an external monitor/projector)
Enter the iBook!
I plug the iBook's VGA adapter into the projector. The projector shows that it recognizes an analog RGB 1024X768 60Hz signal and projects desktop screen immediately. Plug and play!
iBook display prefs reveal:
Color LCD, 1024X768, colors: Millions, Refresh rate: N/A
Color tab: Generic RGB Profile
VGA display, 1024X768, colors: Millions,
Now. I unplug adapter from iBook, iBook readjusts to native display
plugged back in adapter to iBook, immediately recognizes and displays projected desktop.
Scene 2: The FREAKY thing!
Now, I immediately (after unplugging the adapter from the iBook) change adapters to the DVI to VGA adapter and plug the projector into the MacBookPro B, whallla! Back in business. (computer screen adjusted to 800X600, and projector recognized signal).
Now, what about my computer? I unplug from MBP B and plug into MacBookPro A, and NOTHING...the computer doesn't automatically adjust to a new resolution, and the projector doesn't recognize any signal from the computer.
Ahhhh Freak out! Now, I plugged adapter back into MacBookPro B, and now back to NOTHING. MBP B no longer recognizes projector or readjusts it's resolution. Was something somehow corrupted?
Now, I plugged iBook VGA adapter back in, and iBook once again with it's awesome G4 technology (or dated video drivers or something) recognizes the projector in an instant and projects the screen.
Now, logically I try again to immediately unplug the adapter from the iBook and switch adapters and plug back into MacBookPro B-it worked once right? But, sorry, NOT twice. The mystery deepens.
Well, I think, maybe it is because I didn't restart MacBookPro B before attempting the switcharoo from iBook to MacBookPro.
So, I plug back into iBook-projector. And the iBook works immediately again.
I restart MacBookPro B and plug in to the freshly restarted MBP B...HOUSTON WE HAVE LIFT OFF! The MacBookPro B recognizes the projector and the projector kindly displays the desktop.
Now what about MacBookPro A...Last time, when I did the switcharoo, it corrupted something to cause the MBP B not to work. Let's try it again. Will this plug-unplug-restart-switch adapters-immediatly plug in technique work...let's see. I restart MBP A, and plug DVI to VGA adapter in. Sorry. Same ol' no signals recognized. MacBookPro A not auto readjusting resolution, and does not list any projector in display prefs.
Let's get crazy and immediately plug the adapter into the MacBookPro B...it works-oh so logical...NOT! Why wasn't it corrupted this time by MBP A? MacBookPro B readjusts its screen to 800X600 stretched and projector immediately recognizes and projects desktop.
Now lets see if I can break it again as before. I unplug it from MacBookPro B and back into MacBook Pro B, knowing that this caused it to stop working previously. And...it still works-WHAT? I do it a third time. It still works on MacBookPro B.
So,
I plug it back into MacBookPro A...still nothing. Back to MacbookPro B works like a charm. This time it struggles a bit showing that initially it sees a signal from MacBookPro B of 1192X900 (i Think), then the MacBookPro B switches automatically to 800X600 and the projector works.
Wait..I see something amiss! I see in my MBP A menu bar an icon for Labtick which MBP B does not have. I shut down Labtick, plug back in the DVI to VGA adapter and 'Boom' the projector is recognized.
I unplug DVI to VGA adapter and plug back in to MBP A and 'Boom' the projector is recognized again...no it couldn't be!
Well, it is possible it couldn't be because, I shut down the projector, unplug it's power source, plug it back in. I plug it back into the recently working MBP A with Labtick not running, and sorry folks, now the projector doesn't work again. The MBP A does not readjust it's resolution, nor recognize a projector and the projector doesn't recognize the MBP A.
Let's try the projector in MBP B....same deal. Now it doesn't work. Same symptoms of MBP A.
Back to the good ol' iBook. Of course it works.
Now switching over directly to a restarted MBP B. -DOESN'T WORK (as it did using this technique previously)
Now switching over to MBP A- DOESN'T WORK.
As you can see, it is hard even with multiple computers to find a series of doing things that consistently makes the projector work.
Any thoughts, ideas, ways to diagnose? Thanks!

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 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.

HT1338 early 2012 macbook air clamshell mode not working after mountain lion update

Can't make 2012 MBA 13" work in clamshell mode after updating to Mountain Lion. All peripheral devices are connected, as is AC power. Closing lid causes external monitor to enter sleep mode (presumably, the MBA is going to sleep as well).
Power settings are set to stay awake when on AC power.
Thank you.

Hi,
The two may be linked as there is a common support app called IMAgent that helps with both Messages and FaceTime.
Shut down both apps.
With the Finder as the Front App > use the Go Menu > Hold down ALT key and select Library.
In the Library find and open th Preferences Folder
Find com.apple.IMAgent.plist and drag it to the Trash
Before restarting the App now go to Activity Monitor in Applications/Utilities.
Find imagent (it is in lower case).
Highlight and use the Quit button.
Now restart the app(s).
This will recreate the .plist from defaults.

New MacBook Air I5 camera not working because of flash?

I bought a new macbook air I5 13" last night at best buy. This is not my first macbook. However, I can't get the built in camera isight / facetime to work with web based sites. I've logged in and out of different profiles. Installed/Uninstalled flash several times. Already reset the macbook. Done everything that I can find online about fixing this issue and not having any luck. I've spent most of the day reading and browsing this issue. Any help would be greatly appreicatied.

If your webcam doesn't work with Apple apps either, take MBA back to best buy and ask them whether it can be exchanged or repaired. Do this ASAP.
If your ONLY problem is with flash based web sites, see if any of the suggestions here help you: http://discussions.apple.com/message/17214189#17214189

    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

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?

Macbook Air 2012 now wakes up with delay

I got a new Macbook Air 13" in July. 2 weeks later I upgraded to Mountain Lion. Since then the login screen wakes up with a delay of a few seconds from sleep. Even though the login screen displays promptly, the keyboard does not respond ... then there is a screen flicker and then only I can type the password.
This is defintely a bug - any idea how to resolve this?

It is either your CD or your Superdrive (you never said explicitly, but sounds like you are using an external USB superdrive).
Have your tried installing CD/DVD sharing on another computer (if that is an option) and trying the install DVD from that computer (and using remote install)? This may rule out the DVDs themselves. If you do this remember:
1) You will have to connect to wireless or wired network when holding down the option key during MBA boot,
2) You will need to run the "remote install MacOS X" application that you have installed on computer with remote DVD drive,
3) The entire process will take a VERY LONG TIME (including the startup on the installer).

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.
