DVI on my MacBook Pro quit working.

I got a DVI output adapter to display my MacBook on my TV. Last night everything worked fine. Today, nothing will display through to my TV. I haven't updated anything. I've restarted twice. I can't figure why last night I was able to watch several movies on the TV with QuickTime, but today only my desktop background will show through onto the TV. What is wrong?

Sounds like display mirroring has been turned off. You should be able to turn it on again in the display preferences pane under Arrangement.

My speakers on my macbook receiently quit working after I had been using some headphones. My headphones still work whenever I plug them in with both increase and decrease in volume. I have also noticed a red light on the inside of the headphone jack.

My speakers on my macbook pro quit working the other day after using my headphones. when I try to adjust the speakers my screen indicator sayes that it is at full volume on the bar but also muted(circle with line through it). I also noticed a red light inside my headphone jack. My headphones still work including volume. Any quick fix?

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Make sure Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964

Try:
- Resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Resetting network settings: Setting>General>Reset>Reset Network Settings

Your not weird, your a audiophile.

Good sound costs money. And with a 5.1 system your usually doing surround sound decoding for BlueRay movies etc. for home theater purposes.
The PC 5.1 surround sound systems require a audio card in a PC tower and mainly used for playing 3D games so that won't work for any Mac at all. So don't buy a PC 5.1 surround sound system for your Mac.
Harmon Kardon has the GoPlay, it's a portable stereo with awesome sound (not as good as their theater systems) and you can hook up a analog male/male stereo mini cable to it from the Mac.
$200 and it has a iPod dock and also takes like 8 batteries so it's portable.

There is also the Bose Wave clock/radio, you will need a stereo mini to RCA break out cable for that.

The GoPlay has much better sound than the Bose, I think the Bose are overpriced.

I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
Help.

BB1B2,
The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
Sorry,
Clinton

My USB port on my Macbook Pro stopped working and i tried the SMC reset and the one closest to the SD port still continues to not work. Is there anything i can do besides bringing it in?

I would do another SMC reset. If nothing changes you should take the computer in to an Apple store for a free diagnostic. You should make an appointment.

Recently I was working on my home Network and lost myPassword for my Home wireless connection. After many attempts, I remembered thepassword and was able to get in. Now the MacBook Pro only works at home on aHard wire connection. I have an additional 9 devices on the same network, allare functioning properly. The Air connection works fine at any other Networksout side the Home connection. I did a PRAM reset, deleted the Network profileand rebuilt in System Preferences. Still unable to connect wireless on Homenetwork. Any Ideas?

I seem to have fixed it by putting <div class="clearfloat"></div> after the navigation bar?

HT4260 I did everything the article suggests. And for my macbook pro it works perfectly. But all the other devices (iphone 5, 4, Macbook Air) can't connect to the network. Anybody any idea's?

Try resetting your modem. Power it down. Wait a moment, then power it up again. While it resets, do not change what is connected to it.
In another, though unrelated article, Apple recommends the following:
If you have configured your Wi-Fi base stations in the past, it may be helpful to do a factory default reset of each Wi-Fi base station that will be part of the wireless extended network before you begin.
This step really ought not be considered optional for the configuration you propose. If the problem persists after resetting your modem, reset everything else too.

Why does the internet on my new macbook pro not work when my old macbook's does?

Why does the internet on my new macbook pro not work when my old macbook's does? I'll have to turn the wifi off and back on multiple times to get the internet to continue to work on my Macbook Pro (running mountain lion but did it on lion also) when it runs fine on my old white Macbook (running lion). Is there something I can do to fix it or do I just have to deal with it?

Here is your fix .. I have uploaded my properly calibrated profile get it here :
http://www.megaupload.com/?d=YAJL6A9X
And it should go to your user folder/Library/ColorSync/Profiles
if you have one already you can rename either one ..
and then go to system preferences - displays - color to select the profile .
you will get rid of the blue tint while keeping correct color and gamma
This is for the newer 2010 MBP's altho if same display was used might also give good results in the previous models as well . .

USB ports in my macbook pro stop working

For a few months now the USB ports in my Macbook Pro stop working. The mouse is unable to move the pointer, therefore, I have to use the trackpad to select things. Then, when i try to shut it down it refuses to shut down, so I have to hold the on/off button to turn it off. When I turn on the laptop, the problem goes away. It's been happening more often for the last few weeks. Is there a problem with the software or is it the fact that I never used a base to raise the laptop, until recently, to let air in below so it doesnt heat up so much?
Any help is appreciated.

Hi h,
Try an SMC Reset: http://support.apple.com/kb/HT3964

HT1270 Used the right memory, both for my iMac and MacBook Pro, iMac worked, MacBook Pro didn't start (warning tone). Any idea?

Used the right memory according to page, both for my iMac and MacBook Pro, iMac worked, MacBook Pro didn't start (warning tone).
Any idea?

I suggest you buy your memory from OWC or DataMem. Both guarantee the memory works or will replace it if it does not, no questions asked, within their 30 day return period. I've used both for over 20 years, and no complaints.

Macbook pro not working without battery

my macbook pro not working if i remove the battery
& if the battery is empty my macbook pro not working before charging

Try an SMC reset:

You should not run on AC with the battery removed. The MBP should work that way, but the OS throttles back the CPU so running like that is not recommended.

MacBook Pro only works near router...sometimes

I am wasting a good portion of my 39th year on this Earth trying to get my MacBook Pro to connect to my wireless. Comcast has come three times, and swears they aren't the problem.
For the last month and a half, my macbook pro only works near the Comcast router. During the prior two years, it worked throughout the house. I have a PC laptop that was working elsewhere in the house, but also stopped getting wi fi recently.
Now the PC works, but I still can't get Wifi on my macbook pro. My Kindle also can't connect to the wifi.
At one point, a technician suggested getting a netgear router, so I did...and that worked for a week, but now I'm back to the same problem.
The laptop gets wifi fine in cafes.
Help!

Hi Leroy
Thanks for the reply but if you read my OP, I've already tried what you suggested.
Thanks again,
Jacobo
