Digital out constantly on when nothing plugged in.

Well, I've read the threads, seen the responses and was trying to resurrect an old thread that had an answer that intrigued me. Someone had used electronics cleaner fluid. I would like to know what type.
Would WD40 be suficient?
Laptop is out of warranty and I didn't get applecare.

It would probably depend on what might be in the connector. If just dust, then try vacuuming it out. If some foreign matter, it would depend on what it is. If actual corrosion, then possibly some sort of electronic cleaner. But with modern gold plated contacts, I would not expect corrosion to be a problem.
However, I would be very cautious about using any liquid on a connector. There is the possibility that any liquid could wick further in and cause damage. It would be safest to use a good light and a magnifier and inspect the connector very carefully. If you find foreign matter, see if it can be removed with splinter tweezers. Have the machine off while you do this. Look for something bridging one or more contacts. Or bent contacts touching--anything that is wrong.
I would strongly recommend against using any sort of liquid to clean the port. It would be best to inspect it and post back with what you find.
Good luck!

MBP (early 08) shows VGA display when nothing plugged in

My macbook pro early 2008 shows VGA display when there is nothing plugged in. It performs just like there is an actual display plugged into it. I have run AHT and it tells me nothing is wrong. I have reset pram. I deleted all the prefs that relate to the video prefs. It actually works when i do plug a DVI-> VGA Adaptor, but when i plug the DVI-> Video adaptor in only the s-video works. Composite video ends up with out any luminance. My best idea is there is a pin jammed in there from one of the video adaptors, and it's somehow telling the system that there is an adaptor plugged in, but I'm open to trying anything right now. This computer was purchased 3 years and 1 month ago, so it's just out of apple care.

well it is a hardware issue, at least it has nothing to do with OSX. I did recently delete my bootcamp partition, and I know the windows version of the nvidea driver has a bit more control over things, I'm wondering if I should reinstall bootcamp to see if it is something in the Video Card's rom that Windows changed. I read that somewhere in a post on this board somewhere someone was able to easily change this problem in that driver.... why do you think AHT wouldn't catch the issue?

IPod Music Library "Greyed Out" in iTunes when I plug my iPod in... help!

Hi... not sure how to explain this, so I'll do my best... if anyone can help, I'd really appreciate it!
When I plug my video iPod into iTunes via USB, I can see all of the songs in my iPod's music library in iTunes, but they are all "greyed out." The songs in my iTunes are fine and can be accessed, but when I look in the iPod's music library in iTunes, all of the songs show up but are inaccessible. Any ideas??? I'd really appreciate any help!

Grey text when you look at the content and a lock symbol at the bottom of the screen just indicates that the iPod is set to sync automatically with iTunes. If you want to play the iPod songs through iTunes, delete songs from the iPod, drag songs from iTunes, add playlists to the iPod etc. you need to change the update setting to "manually manage songs and videos". The text will change from grey to black and everything will be directly accessible through iTunes:
Managing content manually on iPod
Syncing Music to iPod
Something to remember about using an iPod in manual mode is that the "Do Not Disconnect" message will remain on the display until you physically eject the device: Safely Disconnect IPod

MacBook Pro out of RAM when nothing is running?

Okay so I have a brand new 13 inch non-retina MacBook Pro with a 2.9 GHz i7 and 4GB of RAM. I understand when I am running a game or FCPX why I would get close to or run out of RAM, but as I'm typing this, the only thing I have open is Google Chrome and Activity Monitor. I am using 3.99 out of 4.00 GB. I am planning on upgrading to 8GB soon, but is this normal? I have restarted and that doesn't help me. Here is a picture of Activity Monitor:

It most certainly is normal with Mavericks. Please read this:
http://support.apple.com/kb/HT5890
RAM usage under 10.9 id different than with priors OSX's. Do install the additional 4 GB RAM but relax regarding the current usage.
Ciao.

TOSLINK/SPDIF optical digital out problem

Dunno what the problem is here. I've used a mini-Toslink adapter and cable to successfully send a digital signal to my amplifier with my Macbook Pro and a previous iMac G5 iSight, but recently failed to do the same with my new 24" iMac. The red light and the Sound preferences suggest that the digital output is working, but no sound comes out. The same setup works fine with my MBP's digital output, so I can't explain the problem on the iMac.
Does anyone know of any other ways to test or verify that the digital output is working? Perhaps there is another way to turn the digital output on/off? I'm hoping this is a software issue ...
Thanks.

I'm having a similar problem / issue with the digital outs...
I'm sending a digital signal via a mini-TOSlink adaptor to my MOTU 828mkII ADAT IN... first problem is that unless I set the MOTU's clock to ADAT IN... (and not use it's only internal clock) then I get digital noise when I playback anything on my iMac... since there is no way to set the iMac clock in Audio Midi Setup to External... it's greyed out.
The larger issue is that playback works fine as long as the Audio driver is being used... i.e. iTunes playiing something back. When I stop any audio playback... about 30 seconds later, the MOTU sync light starts flashing as it's NOT receiving a sync signal from the iMac anylonger. Then if I start playback again it takes about 2-3 seconds for the playback to sound. Totally unacceptable...
I noticed a few things... first off... I also send a signal from my MOTU BACK to my iMac through the iMac's digital IN. With the Digital Output on the iMac, plugging in the TOSLINK cable will automatically change the OUTPUT in Audio Midi Setup to Digital Out... when plugging in the 2nd cable to Digital In, Audio Midi Setup DOES NOT change to Digital In unless you start audio playback, and that's where the 2-3 seconds lag comes in. When you actually hear the playback, if Audio Midi Setup is open... you can see the INPUT switch from Line In to Digital In... and if you stop playback, you can see the Digital In go BACK to Line In about 30 secs later... which should NOT be happening... although technically the Digital in should have NO effect on the Digital Out here anyway... and in truth it doesn't... taking the Digital In out of the equation totally - I still see the same issues... just find it interesting that this is happening.
Anyhow, I have no advice to help you out rwcoch... I wish I did... this is ridiculous! I'm going to search a bit more and see if anyone else has anything remotely similar...
Can anyone else try to replicate my issue? Try sending a digital signal to another sound card... ?
Thanks

My iphone4 is not seen on itunes. When I plug the iphone the device does not recognize it but the pc recognizes it as a camera or something. What can I do?

My Iphone is not seen on itunes when I plug it. I've tried everything that I found on the internet. but it still doesn't work, so I can't sync my iphone. What can I do? I have checked all the USB ports, I have desinstalled and installed again itunes, and I have run out of ideas.

When you plug it it, it should recognize it as an Apple IPHONE under devices. It will then bring the Camera/Connection wizard for the photos on the device. When you plug into different USB, it should bring the hardware wizard and tell you what its installing, what happens?
Under Device Manager, under Imaging Devices it will show up as Apple IPHONE. Is this being shown in your computer?

Digital Out activated when regular headphones plugged in.

Hi, guys.
I've been fiddling with this for a couple days now.
When I plug regular headphones or speakers into my MacBooks jack, the systems goes into Digital Out mode and thus, no sound can be heard from the headphones. If I plug them out, the internal speakers go back on and sound is back to normal.
After a lot of researching, I found a common issue, where the microswitch inside the audio jack would get stuck, and therefore the digital audio would always be active, even without anything plugged in. I don't think this is the same issue, since the system DOES KNOW when the jack is free, since I can easily switch back to internal speakers by plugging out. That's why I don't think the microswitch is stuck in my case.
I've noticed the red light turns on when headphones are plugged in. Somehow, it thinks any plug is a digital audio plug.
At this point, I've tried:
SMC reset
Wiggling a toothpick inside the audio jack
Deleting some audio plist files in my preferences folder
MIDI Audio configuration
Any tip will be preciated. I'm not in the mood to send it to have the motherboard replaced.
Thanks a lot for any hints!

Thanks. I already tried that twice, but didn't work.

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5 and 5C. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Contacting Apple for support and service - this includes international calling numbers.
You will find respective repair costs in the appropriate link:

There are third-party firms that do repairs on iDevices, and there are places where you can order parts to DIY if you feel up to the task:
1. iResq or Google for others.

Pay no attention to iinami, the amount of replies to people saying their handsets must have been jailbroken everytime iTunes throws out an error is tremendous. (Clearly you don't need to have any real knowledge to get to level 3 on these forums, let's hope apple's geniuses know a lot more than some of their customers.)

Solution below.
Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

My iphone I fell to the ground yesterday, from a height of approximately 1 meter. after this I trailed off, now only turns on when I plug the usb but the apple appears and just turn off and turn back, there is nothing more that I recommend doing?

With that behavior you need to take the iPhone to an Apple store genius bar for an out-of-warranty replacement. In the US that is $269 for the iPhone 5.

My macbook pro running OS X 10.8.3 freezes when I plug an adapter into the displayport, even when nothing is connected to the other (vga) end. Anyone know a solution? I have used this adapter with a macbook air and it works flawlessly, but the moment I plug into the minidisplayport the macbook pro freezes with a little spinning color wheel that goes on and on. . .

Hello there, sarhang27753.
First thing that would come to mind to resolve the issue would be SMC and PRAM resets. I've linked Knowledge Base articles below:
