My external display via VGA only works when macbook air is shut?
I'm using a MDP to VGA to connect my 2012 Macbook Air to an external display. When the Air is open I can view only the desktop (no open apps). The open apps only appear on the external monitor when I close the Air (after a couple of seconds)!! Have I accidently altered some settings somewhere??? Makes no sense to me.
Update - I ended up spending about an hour on the phone with a very helpful rep from AppleCare. He was also stumped by this problem. We ended up solving it by using a remote screen-share app that allowed him to see what my video card was sending to the external display, and he directed me over the phone to change the settings (quite funny really - it was literally "move your mouse up a tiny bit, now click, now left, etc).
So, my problem is solved for now, albeit in a very cumbersome way. Still amazed that there's no way to fix this properly.

Mini display port - vga only works with lid closed - then computer goes to sleep
my problem is simple, but strange.
I have a 2009 unibody macbook pro. I have 42 in lcd tv. I have a minidisplay to vga adapter and a vga cable. When I try to connect the monitor to the mbp when the lid is open nothing is detected. I do not get any options to change to mirror mode or am able to change any settings regarding the monitor. I can change the resolution of the built in display only. Now for the twist.
If I connect everything, do a restart and close the lid, as the computer boots up the external monitor works. Its the grey boot screen with the apple logo. But as soon as the computer begins to load the desktop, the monitor losses the signal. At first I thought it was going into sleep mode, so I hooked up a usb mouse to keep the computer awake. I tried the process again, and as soon as it goes to the desktop it losses the signal. So I don't think it is sleep mode.
I downloaded the minidisplay prot firmware update, but because the screen is not detected when the lid is open I cant run it. When the lid is closed the computer either goes to sleep or doesn't send the desktop signal and I still cant run it.
Nothing happens if I change between the video cards (9400 and 9600gm). Is it a resolution issue? Do the vga cables have a max resolution that is lower than 1900 x 1200?
What should I do? thanks

External display - maximum resolution only works in safe mode on MBP
I'm having an issue with an external display connected to a 2012 non-retina MacbookPro 15" i7 running 10.9. Monitor is Dell U2713HM, which has a maximum resolution of 2560x1440, and is connected via a Mini-Dipslayport to Displayport cord.
My setup has been working great for over a year, where while at my office I use the macbook closed in "clamshell mode" with the Dell monitor being the only display in use, running at 2560x1440. However today when I came into my office and connected to the dispay as usual, the resolution on the Dell was noticably scaled. System preferences is showing it running Scaled at 1080p, and when I select Best for Display it stretches to a very wide and distorted resolution. I can hold alt and click the Scaled button to display additional resolutions, however the maximum resolution listed is 1600x1200. Same problem regardless of clamshell, mirror, or extended desktop modes.
I've been trying to track down the problem, and have run though the usual procedures: restart, shutdown, reset PRAM, reset SMC, check cord connections, verify disk, repair disk permissions - all to no avail. However when I boot in safe mode the display runs as it should at 2560x1440 without issue, which lets me know its not a problem with the cord or connectioin, but rather something on the OS / GPU side.
I can't for the life of me figure out what is causing the issue. Considering its been working fine for quite some time, and I've made no unusual changes to the MBP in the past 48 hours when the display was working properly, I'm not really sure where to go from here. Hoping to not have to migrate to a new user or repartion my HDD.
Any suggestions on possible solutions?
Thanks.I stumbled upon a fix. Still not sure what caused the issue in the first place, but for anyone having the same issue, the display override script contained on the site below seems to have fixed the issue.

Hi all,
WIFI of Macbook Air works when the notebook started with OS X.
But when I restart the Macbook Air with Win8, the Wifi does not work.
The Macbook Air was bought last month. It is new model. The wifi may be a/c.
Thanks,hey zyzzyxx, you're not the only one with this issue. it happens to me too. as soon as i unplug my cintiq via thunderbolt display my connection shoots straight back to having 20mbps down. i checked it using a speedtest.
ever find a fix for it? -
Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

Please go to the below link to test if you are having a speaker hardware failure.

This will rule out hardware failure, let me know how that goes.

So I tried to upgrade to Mavericks today and it failed (same error as in this post which seemed to be a common problem). It wouldn't let me repair the disk, and after trying all sorts I rebooted my computer in recovery mode - it wouldn't let me reinstall Lion because the hard drive was apparently locked and I could see no way around this. So I decided to restore from a Time Machine backup on an external hard drive and that worked okay, except my MacBook now only works when the external hard drive is connected. If I remove the external hard drive, I'm back to square one as it still won't let me reinstall Lion as the HD is locked!
I have no idea what's going on. HELP!The startup drive is failing, or there is some other internal hardware fault.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

Is there anyway to have an 11 inch mac air connected to an external monitor with lid closed and still be able to see content. I have a wireless ketboard and mouse and have tried everything. Only works when plugged in.
You are referring to a feature called Clamshell Mode, please read Clamshell Mode setup for instructions.

External display via Mini DisplayPort to DVI no longer works with MacBook.
I had not used my external monitor in the last several weeks. I believe there have been a few OSX Lion updates since the last time I used the external monitor. I had installed all the updates prior to connecting my external monitor again. However, a few days ago I tried to connect the external monitor and all I get is a "No Signal" message on my external monitor. The Mini DisplayPort to HDMI works on my LCD TV, so I know the MDP works. I have also replaced the MDP-to-DVI cord and the external display still doesn't work.
I connected the external monitor to another computer running Snow Leopard and the external monitor works. So, the external monitor does work.
I have seen a few posts aboout this, but nobody seems to have a solution that works or is directly on point to my issue. I have tried to use all the scenarios for plugging in the external monitor and external monitor power. I tried to reboot the laptop with and withoout the external monitor connected. Same thing with the exteernal monitor plugged in and no power, etc. Nothing works. I have tried to repeatedly turn the external monitor on and off while connected to the MacBook. Again, that doesn't work.
So, I am open to any help someone may have. Here is what I am running:
MacBook, Aluminum 13" Late 2008
OSX 10.7.3
NVIDIA GeForce 9400MWhile we all have MacBooks in this forum most of us don’t run Lion. There's a Lion Support Community where everybody has Lion. You should also post this question there to increase your chances of getting an answer. Lion seems to have problems with external monitors. https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

iphone 4: Home Button Not Working. The home button only works when it is connected to iTunes, once i disconnet it does not work, i have tried a restore to factory settings but it still is not working. Any suggestions?
Apple, as I said, does not repair your iPhone. All hardware service issues are handled by replacing the unit. So they can't handle the home-button issue without also addressing the issue of the cracked screen, for which they'll almost certainly charge you. But you can make an appointment at an Apple Store or call Apple tech support and plead your case.

Time Capsule Airport
Hello to all, good day, sorry my english google, but it is the tool I have at the moment. I'm having trouble with my Time Capsule Airport, I made all the settings according to the manual, but there has been a connection problem with my iMac. When I finish my work I turn off the imac and then again when they return to work and care, it can not connect to Time Capsule Airport, making it impossible to remove the files and make back up by Time Machine only works when I turn off and turn on the Airport Time Capsule , but I think this may end up with the unit. What can this happening and how to solve? Thank you.
Olá a todos, bom dia, desculpe meu inglês google, mas é a ferramenta que tenho no momento. Estou tendo dificuldades com a minha Airport Time Capsule, fiz todas as configurações de acordo com o manual, mas tem existido um problema de conexão com meu iMac. Quando termino meus trabalhos desligo o imac e depois quando retorno pra trabalhar novamente e ligo, ele não se conecta a Airport Time Capsule, impossibilitando retirar os arquivos e fazer o back-up pelo Time Machine, só funciona quando desligo e ligo a Airport Time Capsule, mas acho que isso pode acabar com o aparelho. O que pode esta acontecendo e como resolver? Obrigado.This is easier to do with pictures perhaps.. since we do not share a common language and machine translation leaves a lot to be desired.
In the airport utility bring up your Time Capsule.
Simply post the screenshots here.
So here is mine.
Click on the Edit button and give us the Internet and Wireless and Network tab..
eg.
Please also make sure you are set to ipv6 in your wireless or ethernet .. whichever is used.. and do tell which.
This is wifi in your computer.
The following are important..
DO not use long names with spaces and non-alphanumeric names.
Use short names, no spaces and pure alphanumeric.
eg TC name. TCgen5
Wireless name TCwifi
Use WPA2 Personal security with 10-20 character pure alphanumeric password.
read apple instructions to help with TM and TC.. they did finally admit it has issues in Mavericks.
OS X Mavericks: Time Machine problems
Mount the TC manually in finder.
AFP://TCgen5.local
When asked for the password .. that is the disk access password and save it in the keychain.
Reset Time Machine
