Why won't my Mac Pro sleep after Lion is installed?

Why won't my Mac Pro sleep after Lion is installed?

Tell us, what hardware add ons?
old software? that required PowerPC/Rosetta maybe.
Look for any apps, process that used powerpc and look for updates, check out RoaringApps for a table of Lion compatible programs
does it happen iwth a clean install?
how about if you do a Safe Boot?

    Why won't my Mac Pro go to sleep?

    Hi X,
    I've been having the same problem of mac pro not going to sleep. I think its to do with some universal audio drivers installed with a recent hardware interface I've added.
    the terminal app in response to above line reads;
    com.uaudio.driver.UAD2System(6.3.1)
    com.uaudio.driver.UAFWAudio(4.0.0
    com.digidesign.iokit.DigiDal(9.0.6f4)
    com.paceap.kext.pacesupport.snowleopard(5.8)
    launch agents (in user)
    com.adobe.ARM.202f4087f2bbde52e3ac2df389f53a4f123223c9cc56a8fd83a6f7ae.plist
    com.apple.FolderActions.enabled.plist
    com.apple.FolderActions.folders.plist
    com.google.keystone.agent.plist
    launch agents and daemons - too many to list
    any idea from this or would you need to see all the files you listed in Mona Gorillas query?
    appreciate your input

    Why won't my Mac Pro load things or let me do a "save as" without locking up ? I have tried to run the Apple Hardware Test and it locks up as well.

    you have anitebook in forum for 65lbs towers
    youneed to repair your disk directory or erase and restore
    and use Recovery Mode in 10.7 and later
    AHT does not lick up, not unless your laptop RAM or mobo has failed totally and died, more common for laptops that overheat, sufferwater damage, but still...

  • Why won't my Mac Pro go to sleep any more?

    I upgraded to yosemite I a few days later I noticed that my mac pro (3.1 early 2008 dual 2.8 xeon processors, two sad's one hdd, 14GB memory) doesn't go to sleep any more.  When I choose sleep from the Apple menu the displays go dark and it looks like it's sleeping, but the system is still humming along, as if a fan or an HDD is still spinning.  I can shut it down just fine, but would really like just to have it go to sleep like it used to.
    I also recently added a PCIe USB 3.0/eSATA card for external connections (From OWC, compatible with my system).
    Any known issues that would cause this?

    Hi ..
    Open System Preferences > Energy Saver then click:  Restore Defaults
    Then select Sleep from the Apple  menu.
    See if that makes a difference.
    If not, reset the PRAM > OS X Yosemite: Reset your computer’s PRAM
    BTW, if connected, external drives can prevent the Mac from going in to sleep mode.

  • Mac Pro sleeps after being woken up by WOL

    Hi Folks
    In order to wake up my Mac Pro on demand, I have set up Wake Over LAN (WOL) over the network and enabled "wake for network access" at System Preferences > Energy Saver on the Mac Pro. Now I am able to wake up the machine from my local router or across the Internet, but just wake up for a little while only.
    The issue is, after the Mac Pro is being woken up by WOL for about 30 seconds, the machine always goes into sleep mode again for no reason. During the short alive period, the virtual machines running on the Mac Pro are pingable   but the monitors are not on and the replaying YouTube video has no audio.
    However, if I click the mouse or press the keyboard, the Mac Pro can be woken up as expected: the monitors are powered on, YouTube video is audible, all VMs are pingable too.
    Why does my Mac Pro get woken up this way? How to fix it?
    Thanks heaps in advance.
    Regards,
    B

    > Now I am able to wake up the machine from my local router or across the Internet, but just wake up for a little while only.
    From my local router, I use below way to wake up the Mac Pro.
    I can also wake up the Mac this way over the Internet.
    For your information, I can successfully wake up other WOL enabled Windows machines this way on the same network with no problem.
    As mentioned, both ways can only wake up the Mac Pro for about 30 seconds, then machine will automatically sleep again though at System Preferences I have set the computer to sleep after "3 hrs" or "never", as shown below.
    What I expect is just to make the Mac Pro back to work the same way like I locally press the keyboard or click the mouse, not to automatically sleep again in seconds.
    Any thought please? Thanks!

    Please explain specifically how you are trying to WOL, what you want to accomplish by doing so, & how long you think whatever it is you want to accomplish should take.
    Also, what VM's are you running & by what method do they run (like via Parallels or whatever).

  • Why won't my Mac Pro 5,1 boot Snow Leopard?

    My old Mac Pro 1,1 died.    I replaced it with a new Mac Pro 5,1.  (dual Westmere quad core)  Apple told me it would run Snow Leopard.  The new machine recognizes my old Snow Leopard hard drives as start-up disks but does not boot past the gray screen apple logo.   I was very good about keeping the operating systems up to date.   I am pretty sure that I have OS 10.6.8 installed...   I have two Snow Leopard disks that won't boot and a Leopard disk that also shows up as a start-up disk that does not boot either.  All stall at the gray screen Apple logo. 
    What gives????
    I am pretty disappointed.   I need Rosetta back!

    MacOSX: versions (builds) for computers
    What this shows is that if you can build a verion of 10.6.8 using another Mac, starting from a "Full Retail" DVD (so that "drivers for every appropriate Mac" are included) it will boot the Mac Pro 5,1 from 2010. Users here have determined that, since the 2012 model uses the same firmware with no significant new hardware changes, it will actually boot that one as well.
    Starting with a DVD that "shipped in  the box" with a different model Mac will not include the right drivers, even after update.

  • Why won't my Mac Pro read a burnt copy of Photoshop CS5?

    I just got myself a Mac Pro. From upgrading my old G4. My Mac Pro is a 2 Dual-Core Intel Xeon 2.66 ghz Version 10.6.8. With a SONY DVD RW DW-D150A Drive and a NVIDIA GeForce 7300 GT graphics/display. So I have plenty of requirements to run CS5..I think. So anyways my friend let me barrow her copy of Photoshop which workered fine on her Macbook. When I tried it on my Mac the disk was read as a blank DVD?? As if nothing was written on the disk? I checked it and yes it is a written disk, so why won't it work? Any suggestions would help.
    Thanks.

    Your friend is not allowed to share her copy of photoshop like that, but that's not related to your problem. You've burned the DVD wrong or your hardware is broken.

  • Why won't my Mac Pro wake up?

    If I put my Mac Pro to sleep, it will not wake up normally. That is, tapping on the space bar, or moving the mouse, do not wake up the computer. I have to press on the power button for a few seconds, listen for the click. (so, manual shut down)  Then I press the power button again, and the computer starts up.
    Also, shut down though computer prompts is not sufficient. I ALWAYS have to use manual shut down to be effective.
    I've talked to apple support a lot, no solution. I brought my Mac Pro to the apple store today, they thought they'd identified the culprit: My wacom tablet.
    At the store, with no Wacom tablet, the computer did wake up from sleep-- I think. It definitely started up normally after a computer prompted shut down. (I mean a shut down achieved with the command under the apple logo on the computer...
    But when I brought the computer back home I had the same problem, even when it wasn't connected to my Wacom tablet.
    Other thing:  If the computer is asleep and I un plug it, then plug it in again to power strip, it will wake up! So is it possible that I'm not getting enough juice coming into my computer?
    Thanks, if anyone has any ideas I would be glad to hear them.

    You need to plug the keyboard into a USB port on the chassis to have the Startup "snag keys" be recognized as well.
    The USB ports on the keyboard only has enough power for ONE low power mouse. Do not plug anything else into those ports, not even a Flash Drive.
    The mouse down/up scrolling default is the iPhone direction. You can change it with a checkbox in System Preferences > Mouse

  • Why won't my macbook pro sleep when I close it?

    To anyone who can help:
    My macbook pro used to go to sleep mode when I closed the display.  Now it does not.  Every time I close the display the computer keeps running.  If I do not manually put it into sleep mode before I close the display, when I come back to it the battery is dead (obviously given that the power cord is unplugged).  I have looked at all the settings in power saver in the system preferences panel, but there are no options regarding sleep mode when the display is shut.  This computer is still quite new, I'm running OSX 10.7.4.
    Is there a setting I haven't found somewhere?
    If not, is there some sort of support that Apple will offer?
    Thanks to anyone who can help.

  • Why won't my Mac recognize Verbatim Dual Layer blank DVDs?

    Why won't my Mac recognize Verbatim Dual Layer blank DVDs?
    I've just completed a 140 minute project in FCP. I've encoded an MPEG2 file that is 5.75GB in size. Brought into DVDSP and am trying to burn the DVD.
    I have Final Cut Studio 1, latest updates and everything.
    Because of the 5.75GB size I need to burn to Dual Layer DVD. I have Verbatim 4x 8.56GB dual layer DVDs.
    When I click buld/burn and pop in a dual layer DVD I get an error saying "please insert compatible disc".
    Even with every app closed. If I put one of these DVDs in my Mac it simply spits it out after about 20 seconds.
    For some reason the Mac won't handle or understand these Dual Layer DVDs.
    I bought this Mac Pro about 4 months ago and it is the 2 x 2.66Ghz Dual Core Intel Xeon machine and the DVD drive (according to system profiler) is a Pioneer DVD-RW DVD-111D. In system profiler it says "Pioneer DVD-RW DVD-111D"
    Can anyone tell me if this DVD player is actually capable of dual layer, or do I need to buy one.
    In System Profiler under Revision it says: AB09 and under Protocol it says: ATAPI
    Can anyone advise please?

    If you have access to a pc into which you can install the 112, or if you have bootcamp, you can replace the Apple supplied firmware with Pioneer firmware. This should restore full functionality to the drive. The latest Pioneer firmware for the drive is version 1.21 and can be found here: http://www.cdrinfo.com/Sections/Firmware/SingleModel.aspx?DriveId=1426

  • Why won't my MacBook Pro's screen turn on?

    Why won't my Mac Book Pro's screen turn on at start up?

    Test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
    Sometimes the cause of the problem may be an outage in Apple's network, in which case none of the steps below will have any effect. You just have to wait for the outage to be fixed. That should rarely, if ever, take more than a few hours.
    Step 1
    Sign in to the App Store by selecting Sign In from the Store menu. If you're already signed in, sign out and then sign in again.
    Step 2
    Log out or restart the computer.
    Step 3
    Remove or disable "LittleSnitch" or any similar third-party software that blocks outgoing network connections according to the developer's instructions.
    Step 4
    Start up in safe mode and log in to the account with the problem.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    After testing, restart as usual (not in safe mode.)
    Step 5
    If possible, connect to a different network and test.
    Step 6
    There are reports that resetting the PRAM may solve the problem in some cases. I can't confirm.
