Macbook Pro master volume changed by iTunes
Running Lion but this problem has existed under prior OS versions. I have had a symptom where the master volume level changes on its own. For example, It set it to full volume then sometime later notice that it is set to about 40%.
Today I finally duplicated the problem using iTunes 10. Volume set to full, I select a song and delete it, and the master volumen is reset to ~40%. This happens every time! I have had it happen outside of iTunes but cannot isolate a pattern like I have with iTunes.
Help appreciated!

Went to the Genius Bar, The tech decised it was a bad logic board. I got a new computer to replace a week old one. After going through setting it up again, I have the same issue. System Profiler sees that an iPhone is connected, but not iTunes. I can not sync to the new MBP. At the moment, I am syncing to my old MBP, just so I have the iPhone set up as I had it.
BTW, if you go through the "iTunes does not see iPhone" suggestions and enter DFU (restore mode) your iPhone gets bricked. But it is recoverable by using a different computer. I am currently trying a NEW install of the OS on the i7, but I suspect a hardware/driver interaction problem. I have no hopes until 10.6.4 arrives in a month or so.

The HD was recently changed on my MacBook Pro and I lost my iTunes library (Time Capsule died also!) but all my songs are still on my iPhone4. How can I copy them back to my laptop? Tks
Your i-device was not designed for unique storage of your media. It is not a backup device and media transfer was planned with you maintaining a master copy of your media on a computer which is itself properly backed up against loss. Syncing is one way, computer to device, updating the device content to the content on the computer, not updating or restoring content on a computer. The exception is iTunes Store purchases which can be transferred to a computer.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer - http://support.apple.com/kb/HT1848 - only purchases from iTunes Store
For transferring other items from an i-device to a computer you will have to use third party commercial software. See this document by turingtest2: Recovering your iTunes library from your iPod or iOS device - https://discussions.apple.com/docs/DOC-3991 -

MacBook Pro: I have changed my old apple ID address but cannot update apps now as it still reverts to my old ID address as the primary holder (it is the apple ID that I have purchased the apps, etc). I have tried to edit back to the old address but it will not let me type in the address and there is no blue edit sign on the rhs. What can I do to rectify this problem?. Is there a waiting period after editing an apple ID address? I have spent the good part of yesterday searching the net and know that there is a major problem with this but wondering if anyone has found a solution. Thank you.
Hello Jamcef,
Thank you for the question. Use these steps to change the Apple ID signed into the iTunes Store:
Sign in with a different Apple ID
Tap Settings > iTunes & App Stores.
Tap your Apple ID.
If you see the option to Sign In, you can change your Apple ID now.
Tap Sign Out.
Enter your Apple ID and Password and tap Sign In.
Or if you don't have another Apple ID, tap Create New Apple ID.
You can find the full article here:

Please help! Itunes fails to open on my macbook pro. I have removed itunes and reinstalled it and it still will not work!
Try removing the Genius database. In the "Finder" go to the /username/Music/iTunes/ folder and delete the "iTunes Library Genius.itdb" file. This may allow the program to launch again. This file will be recreated upon first use of the "Genius" feature.

I have a MacBook Pro, I want to copy Itunes files to an SD card to play in my car, the SD Card doesn't appear in Itunes when I insert it, and I don't know how to convert the files to the correct format, can anyone help?
Thank youSo it seems from reading the COMMAND manual that my first issue is that I used a 16GB SD card, and the manual says it will only recogize up to a 2GB SD card. I did use my MB Air's SD card slot and crated a folder and dragged the music files to it, then to the card. So I am going to get a 2GB card and try that next. Otherwise just stick with the iPOD connected. At least that is 8GB

I have a 3rd gen Ipod touch. When I connect it to my Macbook pro to sync it with itunes, it doesn't show up on iTunes. When I connect my iPhone 6 to my computer it syncs, backs up, ect. How do I make this older iPod show up on my iTunes?
Hi ChristianHelpplz,
Thanks for visiting Apple Support Communities.
It seems like your iPod touch is not recognized by iTunes on your Mac, but your iPhone 6 is working normally.
I recommend starting with these steps to troubleshoot your iPod touch and connection with your Mac:
Check your USB connections
Unplug other USB devices from your Mac and try again.
Try a different USB port.
Try a different USB cable.
Restart your device
Restart your iOS device or reset your iPod.
Restart your Mac
Turn your Mac off and back on.
Update your software
Check for software updates on your Mac.
Check for an iTunes update.
Check your security software
If you have security software installed, learn how to resolve issues between iTunes and your security software.
From:
If you don't see your connected device in iTunes for Mac - Apple Support
If you've tried these steps and your iPod touch is still not recognized, try placing it into Recovery Mode next:
If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

I saved photos from my Macbook Pro onto my Iphone (using itunes, 4 years ago). My macbook is now dead and I need to get the photos I saved off of my iphone 3GS transferred to a pc. Any help... From my PC I can only access "internal storage"
The iphone is not a storage/backup device. The picture sycn is one way - computer to iphone. The photos are also reduced in size when synced to iphone so they are not of the original quality
It has always been very basic to always maintain a backup of your computer.
Have you failed to do this?
If so, not good at all, you can e-mail the pics to yourself - keep in mind they will never be of the original quality -
Using the optical drive of a MacBook Pro from new iMac for iTunes
Can I connect my macbook pro to my new iMac (no optical drive) with ethernet cable and use the optical drive of the macbook pro to upload CDs to iTunes on the new iMac?
On my 17" MacBook Pro I use the eSata port for Black X Duet Hard Drive Docking station where I put 2 1TB Hitachi internal drives. They are swappable and are about $80.00US. I use the USB port for my system backup and a G-force 500 MB bus powered portable drive on the FW800 port just for the heck of it. It works out really well for me.

Every time I plug in my headphones into my Macbook Pro, my volume control buttons don't work.
Every time I plug in my headphones into my Macbook Pro, my volume control buttons don't work. Even after I unplug my headphones they don't work, they get stuck on the level of volume it was at when I plugged in the headphones. I can control the volume if I go to system preferences and do it that way, but that is such a pain. Also, in order to get the buttons to work again I have to completely restart my computer which is also a pain! What should I do, or can do, to fix the problem?
If you have have lion system, herebis a digital/analong output, youmcan a tooth/Qip with the the tip cut off you can you can stirrted s very gently to the input/put is a digital/along output devivce\\\\\\\\\\\\\

For the past week or so, I have made changes to the calendar on my MacBook Pro. The changes do not "stick" on my MacBook calendar and do not sync with any other device (iPhone or iPad). I just can't figure this out. Anyone have any suggestions?
By everything, I am assuming you have tried resetting the SMC (http://support.apple.com/kb/HT3964) and PRAM (http://support.apple.com/kb/ht1379). If you haven't tried this yet, please do!
See the following support document as well: http://support.apple.com/kb/TS1367.
The update you're talking about was the firmware update. Hopefully resetting the PRAM gets you up and running. Try resetting it 3 times in a row (hold the keys down until you hear 3 startup chimes).

Macbook Pro 15" volume level changes by itself
Hi all!
About a month ago I have upgraded my rock-solid Macbook Pro 15" (mid 2012) from Mountain Lion to Mavericks. All seemed fine (with the exception of some known annoyances with WIFI) until last week when all of a sudden the volume level started to change by itself. It started going up and down, turning mute and turning on again and so on, just like an invisible hand or a remote access have taken control of my machine (it wouldn't even let me change the the volume using the volume buttons while this weirdness is happening). This has never happened before. To make things worse, I have then upgraded to Yosemite and all seemed fine but then the weird volume changes appeared again and I now am stuck with no straight forward way of reverting all the way back to the original Lion (which worked perfectly since Mac purchase back in 2012).
Can anyone help?
I have googled for similar issues and have seen some answers (mostly not that relevant) including a thread on this forum suggesting to reset the SMC. I have tried that using the suggested key-combination press, but it did not seam to have solved the problem, as the volime changes continue when I least expect it.
Is this a hardware problem? If so, would a change of the keyboard resolve things? [ At some stage I thought maybe the problem was caused by the fact the I have fiddled a little bit with the keyboard by lifting the :; key (next to L and under P) and applying a bit of WD40 to clean a tiny spil of sugary liqid that caused the key to get sticky. But the volume keys are way far on top of keybord so my assumtion was/is that the volume changes would not be related to the cleaning. ]
is this a software problem? Some thread on similar (not identical) issues had suggested there are some bugs in soft and Apple is aware. For this reason I gave Yosemite a go but the problem continues. Would reverting to Lion sole the problem you think? [ Maybe I should ask here if anyone can suggest how to go about this downgrade as Option-Cmd-R key-combination press at start up does not give me the Interner Recovery scree anymore, but keeps taking me (just like Cmd-R) straight to the OSX Utilities where can wipe of the disk (which I did) and reinstall Yosemite only. ]
I would very much apreciate any replies that might help me solve this issue.
Many thanks
