Apple TV and sleeping iMac

Why would my iMac go into sleep mode while Apple TV is accessing content from it?  Does it not recognize this action as "in use" and therefore sticks to its original sleep setting?

Apple has some information and troubleshooting suggestions in this support article:

Perhaps that will help.

  • HT200153 I have Apple TV, an Apple router and an iMac.  I rented a movie from Apple and downloaded it to my computer.  How do I get it to play on my TV?

    As I stated above:  I have an Apple TV, an Apple Router and an iMac.  I downloaded a movie I rented from the Apple store.  I downloaded it to my computer.  How do I get it to play on the TV?

    Two ways.  The easiest is to play it through the purchased items on Apple TV.  The second way is to play through home sharing from iTunes on your computer by clicking on the Computers icon on the Apple TV.
    Have a nice day.

  • HT4914 Sounds like, because my wife and I have separate Apple ID and separate iMacs, that we would not be able to use iTunes Match as a single unit/account?

    Welcome to the Apple Community.
    If you are using different ID's for iTunes, then unfortunately you can't share an iTunes Match subscription.

  • Arrgh!! Apple TV2 and new iMac

    I have a new iMac - it's lovely but my ATV2 just won't work any more.  When I go into "computers" it just can't see it, although youtube etc works just fibe.
    I've restarted everything and I did manage to get it working briefly - but why won't it 'just work'?

    Andy,
    if you have a "new Mac", surely you're not on OS X 10.4.8 ? you may want to update your profile.
    anyhoo, for the iMac and TV to play nicely, you need to set up home sharing on both devices. if you've done that, verify you did so correctly by following the instructions in the following support article:

  • Connecting Apple TV 2 to iMac

    Is there any way that i would be able to use my imac an external display for my apple tv 2?? i belive i have the right wires to do it but am unable to navigate settings on the imac to get it to work.
    Hope someone can help
    George

    Thanks for the reply and I appologise for not getting back sooner, been away.
    It seems that the iMac requires a reboot for any network changes to take effect, at least that is the experience here.
    I have a My Book attached to the iMac via usb which is accessable by apple tv and the imac, it is formated in NTFS.  It will not show up on the Macbook air, no matter what username and PW is sign on with.
    Thanks.

  • I upgraded to Mavericks and my iMac monitor goes black randomly, but my attached cinema monitor stays active. I can fix it by putting it to sleep and waking it up again. But often it happens immediately after.

    I have a 30in cinema display attached to my iMac and the iMac screen randomly goes black while the cinema stays active. I can put it to sleep and log back in which fixes it, but often it happens again immediately after. Sometimes it happens so quickly I can't even finishing logging in! I'd like to know if this is a Mavericks issue and I will roll my machine back. Thank you!

    Wanted to update you on my situation with this.
    So far 8 hours have gone by and I have not had a screen blackout.
    FIRST I did the Hardware Test. TWICE on the extended test, the instructions on the KB Article explain. It took almost 3 hours, but while the test was running, both times, my computer screen did not go black.
    I did get an error message, both times. Different each time. I looked up both of the error messages on discussion boards. Lots of conflicting info
    One good thread said my first error was that my hard drive was bad and would probably fail.
    The next error message I researched said that a fan was bad or needed replacement.
    (information comes from other folks on discussion boards, not from Apple or technician)
    Not sure what exactly those 2 error messages indicate but I followed a thread where someone found a solution by doing the following. So far it's worked.
    After Hardware Test I did a shutdown and an SMC resest. Unplugged computer power source from wall and computer for about 10 minutes.
    Finally after a restart  I downloaded "SMC Fan Control" (CNET Downloads has a nice safe copy you can download)
    There is a temperature monitor and from what I've read so far, keeping the CPU temperature under 50˚C is ideal. Making sure your fans and computer is in a well ventilated area/room too of course.
    The SMC Fan Control helps you set your own speeds on the fans and so far everything has been going normal.

    As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
    You are now in a perfect position to do a
    SMC RESET

    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    It is the 5 second timing that initiates the reset.

  • I am quite fed up with Apple and my iMac - multiple issues

    I've been a Windows user for years. I've suffered through all of the ups and downs of Windows over the years, mostly the downs. I have three Windows 7 computers, and quite frankly, both have performed quite beautifully, albeit without the polish of the Mac.
    Earlier this year, I decided to buy an iMac for a few reasons. First, they are just so beautiful, and even if you are going to run Windows they are probably the best Windows computers out there. Second, I wanted to do more video editing and found the Windows tools weren't very good. I also wanted to run some karaoke software (kJams) that at the time was not available for Windows.
    I was basically pleased with the iMac for a few months. However, there was one problem I could never solve: the wifi connection got lost periodically, even though I had made all of the system updates. I know this is a problem with the iMac, because my numerous Windows PCs and my two iPod toouches had no problem with a wifi connection. It appears from various posts here that this is indeed a problem many others have experienced since Snow Leopard's release, and as far as I can tell, despite many updates to the Airport software it has never been fixed by Apple. Strike 1.
    A couple of weeks ago, my iMac started running slow for no reason I could identify. I don't have a lot of software installed on it, I didn't download anything pirated or questionable. I did install bootcamp according to Apple's instructions, and it worked fine (I wanted to run some Windows games). I tried doing all of the things that folks suggest when your computer is running slow - repairing permissions, running Onyx, etc. None of them seemed to do anything. I tried creating a new user, it had the same problem. I also noticed various other problems with the computer: it was slow to recognize a USB hard drive (and sometimes didn't recognize it at all), external hard drives would not appear in the time machine set up, and various other problems I can't quite recall. Overall, while presumably nothing serious should have been wrong with my computer, I decided I probably should simply reinstall OS X. Strike 2.
    Now, quite frankly I would have been happy to simply reset the computer to its factory state. I would point out that nearly all Windows PCs come with a separate repair partition where it is very easy to do that with one click. I guess Apple is so confident in the reliability of its computers it doesn't think this is a useful feature. So, I had to install OS X using the DVD that came with the computer. It took quite a while to do this, and actually it wasn't at all clear to me that my settings would be kept (one would think that this is something the install screen would point out - Windows makes a quite clear distinction between a "clean install" and a re-install).
    I was somewhat pleased when all of my settings were there. After the long process of reinstalling, I click on the "Accounts" setting I get a message saying that the Preferences application has quit unexpectedly -- clearly there are still problems. Quite irritating given that I just spent an hour trying to re-install the OS. I google around and again find others have had this problem, but unfortunately none of the proposed fixes I try seem to work. And my computer still seems to have other problems - it still doesn't recognize external drives very well. I will say that it seemed to be running a little faster though. Strike 3.
    Anyway, I decide I need to do a full clean install. When I do that, things seem to be working better, although the mouse pointer is quite jerky - I'm thinking that maybe I need to just run software update to fix that. I start the software update - a nice 1gb download is required. Now ,the problem is that I STILL HAVE THE PROBLEM WITH WIFI DISCONNECTIONS. So no matter how many times I start the download, I CAN"T FINISH IT. And Apple, in its infinite wisdom, HAS NOT WRITTEN A DOWNLOADER THAT IS SMART ENOUGH TO CONTINUE WHERE IT LEFT OFF. How hard is this to do, really? Do I now have to lug my iMac across the house to put it on a wired connection? I've already wasted hours trying to get this piece of junk working.
    And the sad fact is, once I am done, I will have a very beautiful computer that can't hold an internet connection.
    I have to give Apple kudos for the iMac hardware. It's great. But the software? It's fine as long as it works. But it doesn't always work - and when it doesn't, it actually at this point seems more buggy and difficult to repair than Windows. Is this the last Mac I'll ever buy? Probably. Quite frankly, it's hard to avoid the conclusion that Apple's best developers have moved on to more exciting pastures (iPhone for example). And given the number of unsolved issues posted on these forums (including the ones I mention here), it appears that Apple engineers are simply asleep at the switch.

    How do I change from WEP to WPA security, which I have been told is better. I'm sure it is simple but i cant find it.
    These settings are in your wireless router, so you will have to consult the manual for how to access the administration page and change the wireless security settings. Once you have WPA or WPA2 enabled, you will need to reauthenticate your computer with the wireless network since you will have a new password. If you have problems with persistent password requests popping up, you will need to open the "Keychain Access" utility and remove all keychain entries associated with your wireless network and password.

    As for restore, it is different, won't be the same, but there are two ways to handle that on a Mac:
    Apple TimeMachine
    Clone OS X: bootable (yes, you can boot from 2nd or 3rd hard drive) - SuperDuper ($29) is superb and I update the backup (15 minutes) before applying updates.
    That way I have my previous system with all data, not just an image, all my data and going back in time.
    From another thread:
    if you have issues when using an AirPort router, you've either got interference issues causing your problems or a system issue.
    whenever possible:
    1) Vist an Apple Store
    2) Try your machine on their network
    3) If the connection drops, make them fix it.
    Reason being, I've tried and checked log after log and have never seen a connection drop inside an Apple Store.
    My gut reaction would be interference but the easiest move may be to check it in an Apple Store if at all possible.

    When I turn on my iMac it comes up with the login icons which I then choose and log into. The password works and I then get the apple icon and the spinning wheel. After about a minute the Apple icon turns into a prohibited icon. However, if I log in under the guest icon, I can access the wifi and get to Safari. I really don't know what to do next. Any help would be gratefully appreciated.

    Are you running any A-V? If it's an iMac 21.5, I don't think you're running Leopard, 10.5. Probably at least Snow Leopard, 10.6. This is the Leopard forum.

    The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
    1. You don't own another Mac.
    If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
    If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    2. You do own another Mac.
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
    After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
    3. Other issues
    If you see a lock screen when trying to boot from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another authorized service provider to be unlocked. You may be asked for proof of ownership.
    If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
    If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
    When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information.

    I purchased my iMac used.  When I try to update apps in AppStore, the computer automatically fills in the previous owner's email address and it won't let me delete it to enter mine.  I have been using my own apple ID and password on this computer for other things without a problem.  Any ideas?

    Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
    The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
    How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
    It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
    1. If you don't own another Mac
    a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind.

    d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
    2. If you do own another Mac
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    3. Partition and install OS X
    a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
    b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the  Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
    c. An unusual problem may arise if all the following conditions apply:
              OS X 10.7 or later was installed by the previous owner
              The startup volume was encrypted with FileVault
              You're booted in Recovery mode (that is, not from a 10.6 installation disc)
    In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
    d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store.

Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
    b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
    c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one.

  • I may have deleted some system files from my computer due to my antivirus and now my imac won't start. Actually it does, and then there is a blank screeen with the apple logo and it shuts down right away. is tehre a possibility of recovering my files?

    Hello
    I was having some problems with my Imac, for a while it was slow and often disconneceted from my wifi, while this one worked perfectly (tested with other devices)
    I thoug i might have a virus, so i downloaded an antivirus (mac keeper) and started checking.
    I also did a scan of my computer using Console or something from the utilities, and then a folder popped witha  file I had canceled a while ago. I canceled the file and then my Imac continued to be slow.
    i then restarted my Imac, but when it started, the usual grey logo of Apple appeared, and then it shut down suddently.
    I tried to reboot it holding the command key and R but nothing, and then i tried holding the shift key and a bar appeared, and at half of the bar it sut itself down again.
    I think it is probably a preoblem because I may have cancelled some of the system files from a folder called "private" in the "documents" folder.
    Is there any way I can recover some of my files? maybe all of them? I hope so because I have some important files there
    Is this a thing I can do myself or do Ineed to go to a MacStore to repair it? Will I need to change HD or just to format it and reinstall? also if there is any way i can recover some of my files that would be great.
    Thanks

    P.S. problems appeared when i installed the Mavericks version.

    If MacKeeper corrupted the Recovery partition then even I underestimated its potential for damage. Garbage "cleaning" apps will cause misery but I have not found that the Recovery partition to have been affected by using MacKeeper or anything like it. I doubt that it did so, but I have learned not to underestimate the potential for such things to result in system corruption.
    Before concluding your Mac has a hardware failure, try booting OS X Internet Recovery by holding command option r on startup (three fingers). That will force your iMac to bypass the Recovery partition altogether, and convey the ability to create a new one.
    An Internet connection will be required (wired or wireless).
    At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
    Assuming the HD remains usable you can then use Disk Utility to erase it. Reinstall OS X, restore your essential software and other files, and don't reinstall the junk.

  • TS2570 On start up of my new iMac it locks on the grey screen with the apple logo and the progress wheel spins. Boot up in safe and this is where it stopped at "BootCacheControl: Unable to open /var/db/bootcache.playlist: 2 no such file or directory. "

    Reinstalling MacOS does NOT fix the problem for me.  I'm still searching a solution !
