ITunes 10.4 and iMac screen bug.
iTunes 10.4 on Lion won't allow my 27 iMac screen to sleep manually or via energy saver preferences when accessing media via apple tv2. Reverting back to iTunes 10.3.1 fixes issue. Any fix?
Alpemand,
Check out this post: http://forums.macrumors.com/showthread.php?t=1193476
The mothod mentioned involves removing 10.4 and then using Time Machine to restore your previous iTunes 10.3. Haven't tried this method myself, but others on that post have.
Hope this helps...

ITunes 10.4 and Windows 7 bug thread
I thought I would start an entire thread devoted to iTunes 10.4 and Windows 7 bugs since there are MANY people reporting various issues and may not know about all of them. Hopefully this will combine a list of all bugs for reference and help others. So far, most of this effects Windows 7 64 bit, but some are reporting issues under 32 bit too.
I have spoken with both Apple Care and a higher level tech at iTunes support. The iTunes support tech said they were "looking into all reported bugs and are aware of issues with version 10.4, especially under Windows 7. They encourage others to report their bugs to iTunes support so they can work on this and find all the issues.
KNOWN BUGS:
Album Art copy/paste broken - A bug that causes copy/pase from clipboard where album art is not displayed in the info tab as before. Some have reported success by dragging the image file over to it vs copy/paste method but it is still very much spotty and a known bug.
iTunes store not working - Some have been effected with the iTunes store not working properly for them. Personally I don't have a problem but this has been for some.
"Purchases" link not working in iTunes - When you click on "Purchases" link on the right column, all your purchases are missing and do not show up. This includes, music, movies, apps, etc. This is also a known bug and one that I have personally. Works fine in iTunes 10.3 for Windows 7 64bit and also works fine under both Snow Leopard and Lion OS.
Sync issues - Some have reported syncing issues since upgrading to 10.4 iTunes on Windows 7. This is a bit spotty as well as I have no trouble but there are others that have reported issues.
Solutions:
For now, the only way to fix this is to use iTunes 10.4 under Snow Leopard or Lion OS. Also, you can uninstall (not repair) 10.4 and install 10.3 again which should work.You are correct and I wish that I had known this before spending 4 days and a lot of trouble going over this with both Apple Care and iTunes support. They had me jumping through hoops and didn't know anything until it was finally escalated. Only then did I get a vague response like I mentioned in the first post. It's troubling to me how a simple response from anyone there could've just said we know about this and they are bugs in 10.4 causing this.
There are other issues too as you point out with the syncing and crashing. Anyway, hopefully others will find information here more useful than calling Apple for help. Not much we can do now except roll back to 10.3 for those that kept it and hope also they can updated Apple Application Support component. -
ITunes video wakes my iMac screen
Okay, I know this is counterintuitive, but I want to put the display of my iMac to sleep while playing video. It's in my bedroom, and I like to listen to TV shows when going to sleep.
However, the screen will not stay asleep. Whether I use a hot corner or Ctl+Shft+Eject, the backlight turns off for a few seconds, then the backlight comes on and the screen displays the login prompt.
I want the backlight OFF, as the screen is fantastically bright even when it's black.
If iTunes is not playing video, the backlight remains asleep as it should, so this isn't a mouse driver issue or some program or network access waking the machine. If iTunes is playing music, the screen stays asleep as desired.
Is there a setting in iTunes to play only audio from a video program, or otherwise fool iTunes into not realizing it is playing video?
Alternately, a setting to tell the display to stay asleep until I manually wake it, no matter what?
I have already tried changing the preferences to play video in separate window, in artwork viewer, etc.
Any thoughts?
Thanks.The first thing we need to know is exactly which model iMac you have and which model projector you have. This will help us point you to the correct video adapter/cable. Video output standards have changed dramatically over the years utilizing both analog and digital signals. Once we know which outputs and inputs each device has we can make a recommendation.
Here's an article that shows the various Apple video ports.
http://support.apple.com/kb/PH10567
Your project will likely have one or all of the following VGA (analog), DVI (digital), or HDMI ports that can be used to connect your iMac.
This article lists the various video cables and adapters available from Apple.

Itunes stops playing and the screen goes dark
Hi, I have macbook pro 13" and had never experienced this until yesterday and today. The itunes stops playing music, the screen goes dark and it's still charging. Has anyone experienced it?
Boot from you install disc, run Disk Utility. The startup disk may need repairing.

File sharing between rMBP and iMac massive bugs.
I recieved my new rMBP this week to replace my Macbook Air and join my iMac and Mac mini and immediately came across a problem.
Ive always had file sharing enabled on all computers and sent and recieved files to the iMac from the Macbook Air with ease.
However I tried to copy a file from the iMac to my rMBP and was provided with an error code (-8000 something) and was forced to relaunch finder.
I brought the Macbook Air back up (incidently I used migration assistant to copy files and settings over from MBA) and it was able to send and recieve files from iMac with no problems.
The first thing I notice is that the rMBP asks for an admin password to write to the iMac - the MBA doesn't. If I check permission settings on folders from the iMac from both machines they both have the same permissions set so I can't understand this.
Now the error code when trying to copy from rMBP to iMac doesn't appear - instead I send a file and Finder goes crazy and copies a 0 byte file with the same file name onto the iMac thousands of times until I force Finder to relaunch again.
Incidently I can send files to and from the Mac Mini without any issues - and I can as of now recieve files from the iMac ok, but not send to.
Its a very odd bug, ive tried repairing permissions on both machines and restarting both but ot no avail. Can anyone think of anything to delete/reset/try to fix this odd behavour?Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Step 1 should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary, and if everything is working as expected after step 1.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar. -

The latest version of iTunes is defective and crashes making bug troubles
The latest version of iTunes for Windows is crashing and deleting anything, including purchased or syncronized form iPod music stored in it every time the PC is turned off.
I was unaware of this problem, and continued to authorize the new iTunes on new PC at any request. Now I have still one PC with one iTunes on it, but all authorizations are finished, becouse the iTunes believes that all five more PC's were authorized.
Also I changed to new PC, and downloaded new iTunes on it. This way my iPod does not recongises the new iTunes on new PC in order to link and sync.
All the songs bought on iPod cannot be sync and transfered to the iTunes, and vice versa, all songs bought or stored from CD on iTunes cannot be synchronised with the iPod.If you have a Windows computer: http://support.apple.com/kb/TS1538

I downloaded a video course from iTunes U to my iMac. How do I transfer the video to Apple TV to watch on my big screen TV?
I do something like that, and can confirm 20 feet won't be a problem. More than 30 or so might be.

External Monitor with iTunes - iMac screen goes black
I have an iMac with iTunes 7.7/Leopard and an external VGA monitor (I use the standard Apple mini-DVI to VGA converter) then I use the external monitor to watch video from my iTunes library.
All works well - I have my desktop spread over both monitors, I fire up a movie from iTunes, move the video window across to the external monitor and everything is good - I can watch the video on the external monitor whilst continuing to work on my Mac - the iMac screen displays the Mac desktop as normal.
However, if I put the movie into fullscreen mode (view -> fullscreen on the iTunes menu), the external monitor displays the movie in fullscreen mode as it should, however the iMac monitor goes black.
The only way to fix this is to exit fullscreen mode and go back to one of the view options (rg fit to screen).
Any ideas how I can have my external monitor in fullscreen mode and have my desktop back?
Many thanks

My iMac screen freezes and a grey colour slowly creeps down my screen
Hi, my iMac screen freezes and a grey colour slowly creeps down the screen and has a large black square in the centre saying "You must restart your computer by pressing the power button and then pressing it again to restart" or words to that effect in English and about 4 or 5 other languages. I find this happens more frequently when I try to stream movies or tv shows. It also happened when I was trying to download a couple of tv shows from iTunes.
It also sometimes makes a wierd sound a kind of loud noise like a record stuck in a groove. This has happend many times since upgrading to Lion. I hear a lot of people on here talking about their screens going completely black and not responding. I believe that mine has only gone black a couple of times and I couldn't wake it up from "sleep mode" with the mouse or keyboard. I don't know if this is also happening to other people, but my bluetooth keyboard keeps disconnecting all the time since the upgrade as well, it's driving me nuts!! Plus my wifi will show that it is fully operational, however, I can't use the internet when I wake my computer from sleep mode. I have to click on wifi and turn wifi off then on again before i can use it.
Is Apple going to come out with a fix or are we going to eternally suffer indefinitley.Hi Eric,
I don't know why it didn't work before, but here is the most recent errol log. It crashed again about an hour later. If there is a solution, i would greatly appreciate knowing what it is because I can't enjoy using my computer anymore because of these constant crasahes.
Thanks for your time.

IMac screen is black and won't turn on
I got a 27" iMac (intel) a couple months ago (mid-year 2010) and sometimes the screen won't start up after it goes to sleep. Most of the time, I will leave the computer and the screensaver will start then the display will turn off and go black. When I return and hit a button on the bluetooth keyboard or move the Magic Mouse around, the computer will come out of sleep, display will turn on, and everything works the way it's supposed to. However, every now and then, the screen will go to sleep (turn black) and it won't turn back on when I hit the keyboard and move the mouse. I can just barely hear the fan still working, so I know the computer is on but asleep. Even when I hit the power button or hold it nothing happens, it won't even restart. I have to physically unplug the power cord and replug it back in then hit the power button to get the computer to start up again. I have moved the computer around to different outlets and even tried it at a different house, but this issue still occurs. Am I doing something wrong with the Energy Saver settings or is there just something wrong with my computer?
Thanks!Hi, I hope you find this information useful:
A few years ago, we purchased iMac 27" 11,3 (Mid-2010) (with i7 2.93Ghz, ATI 5750 1GB VidRam, etc.) for our offices and software development team. They were originally shipped with Snow Leopard and worked as expected and without any problems. However, a year later, we upgraded to Lion and all of machines immediately exhibited the same problem: the screen would go to sleep by itself and would require a hard reboot or sleep on/off. (Only the screen was asleep and the rest of the iMac continued to function; this was confirmed by screen sharing to the machine.)
Due to the severity and impact on our business, we immediately contacted Apple and their genius bar staff in New York/SoHo. They were unable to determine the root cause, so they replaced all of the logic boards, video cards, and screens, and got us back online asap. This resolved the problem, but we were curious to know why. After days of rigorous testing, we concluded that the issue is caused by a bug in MacOS. Specifically, faulty Kext files (Kernel Extension files extend the functionality of the MacOS Kernel) for the ATI drivers. So, why did the replacing the hardware work? We think that the Kext files that were released and distributed with Lion (and later MacOS versions) correctly supported the newer hardware revision of the replacement components, but not the older ones.
If you're experiencing this problem, short of replacing the components or waiting (for another 3+ years) for Apple to hopefully fix their OS software, you can lessen the effects and be able to recover faster by doing the following: (Please bear in mind that these are not permanent fixes.)
Turn on "Hot Corners" and assign one corner to "Put Display To Sleep". When your screen goes to sleep, move your mouse (which still works) to that assigned screen corner for a second, then move it again. This will wake your screen. You may have to do this a couple of times, but it's much faster than a hard reboot or a sleep on/off for your iMac.
Turn the brightness of your screen to a low setting (10%-15% of the total brightness).
Turn on screen sharing, so you have a last resort method of accessing the machine.
If you're not convinced that it's a MacOS software problem, then do what we did and see for yourself; install Windows 7, Windows 8, or Linux via Bootcamp or as the only OS on the iMac. Those operating systems and drivers worked flawlessly for us; the bug does not occur and the screen does not go to sleep, but if you dual boot and switch back to MacOS, the bug reappears because the iMac is loading faulty Apple MacOS software.
Good luck! -
I installed iOS7 on my iPhone5 and now I am unable to open iTunes - the screen just stays blank.
I have checked date and time and wifi settings.
Not sure what else to do.
I do have iMatch active on my device and its working fine on my other iPohne with iOS7 installed.
Any help please!Have you tried logging out of your account on your phone by tapping on your id in Settings > iTunes & App Store and then logging back in ? If it's still the same after that then try a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.

ITunes opens to a white screen and nothing more
Hi all,
I updated to the latest iTunes 11.whatever and my iTunes just will not open despite my trying all the suggestions in help articles by Apple: opening in Safety mode, restarting computer, reinstalling iTunes, updating Windows, deleting Security software. etc. etc. Suggestions? I've never had problems like this before. I'm on an Acer Aspire laptop running windows 7.I've been having the same issue. Updated to the latest iTunes and the first thing that happens is it displays "Checking iTunes Libary" for about 5 minutes. When iTunes finally opens, all I get is a white screen with my cursor displaying the spinning blue donut indicitive of waiting for the program. I've tried uninstalling and reinstalling iTunes as well as completely uninstalling all the Apple software on my computer and reinstalling iTunes. I've never had this problem before and at this point I'm considering switching to different software if I can't get this resolved. I'm running Windows 8.1 on a Samsung laptop that is only around 3 months old.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.
