10.1 Visualizer FPS Stinks, and Goes to Sleep?

The Frame rate is lousy on the iTunes 10.1 visualizer compared to 9. It appears to occur when the "cloud" effects kick in. Any way to tone the background cloud effects down so the rest of the effects look smooth?
Also, the computer no longer recognizes iTunes visualizer at full screen as an active application, so my computer goes to sleep at the time that is set in the energy saver as if iTunes was not even running. I can't seem to find a way to fix this within iTunes so the machine does not blank my screen. Any ideas?
Thanks!

There's lots of people complaining about this on the message boards.
Try using your "Exposé" System Preferences to set one of your screen corners to "disable screen saver". Then after you start the visualizer, move your mouse into that corner.
That was suggested in this thread - http://discussions.apple.com/thread.jspa?threadID=2567786
It won't prevent your computer from going to sleep though.
Another thing that might work (I haven't tried yet) is to use Caffeine - http://www.lightheadsw.com/ - which will prevent everything that kicks in when the computer is idle (screensaver, sleep, auto-logout, etc). Activate caffeine for a specific period of time, then start your visualizer.

  • Streaming audio from my IPAD to my Apple TV from Rhapsody application.  when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.

    I am Streaming audio from my IPAD to my Apple TV from Rhapsody application.  when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.  I am using the Optical Out from the Apple TV to my receiver, the Apple TV is hard Wired to the Network, the IPAD is Wirelessly attached to the network (it continues to play the Audio Stream).  When the Apple TV is turned back on it resumes playing once I manual select it for output from the IPAD.  All device are on current releases of software.  I have no Video hooked up to the Apple TV.  How do I correct this?

    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

  • My macbook boots up and only stays on for 30sec and goes into sleep mode

    My macbook boots up and only stays on for 30sec and goes into sleep mode! Any suggestions as to why this might be happening? Thanks....

    I assume you have checked your sleep settings in System Preferences>Energy saver
    I also assume this has just happened recently and spontaneously, not after installing any particular hardware or software or you would probably have mentioned it...if anything new has been added recently, obviously just remove it!
    It could be the battery - have your tried it just on mains? If it's a pre unibody MacBook try it without the battery at all. This could happen if you have a non-Apple (cheap Chinese) replacement battery.
    Try NVRAM, PRAM & SMC resets (Google if you don't know how)
    Try booting from the install media and repairing or reinstalling OS X. (Back up first!)
    Just out of interest if you boot from a DVD or go into Open Firmware or Boot Select modes, does it still sleep after 30 seconds or is it just in OS X?

  • Intel imac 24" seems to overheat top LH corner and goes to sleep

    Intel iMac 24" - Since upgrading to Lion, my iMac keeps halting - particularly whilst playing back video - and goes into sleep mode.
    The iMac is very hot in the top left hand corner so I assume that there is a thermal safety cut-out that is putting it to sleep ?
    Tapping the keyboard a few seconds later staarts it up again but very soon heating issue causes it to go to sleep again.
    I've never opended it up so I don't know what componenet is sitting in the top LH corner that is getting very hot - suspect its the graphics card.
    anyone else had the same issue and know how it can be resolved ?
    tia,

    Your machine is working kind of hard, the first thing I'd try is doing both a SMC and PRAM resets, in fact doing 2 of each wouldn't hurt.
    With only 493MB of free RAM you should upgrade. One thing you can check when you do this is to see if there is any dust that has accumulated on the intake port, this could be obstruction air flow. Do NOT blow are in but you can vacuum it out. I would recommend using www.macsales.com (OWC) and Crucial as vendors. I prefer OWC because they specialize in Macs so you know what they sell works, have terrific customer service and competitive pricing.  BTW OWC has how-to videos that show how to install RAM.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • IBook G4 goes from 40% and goes to sleep without warning

    Whenever I have my iBook G4 on battery power, at about 40% it just suddenly goes to sleep without warning. I can't wake it up until it is back on the charger but the light on the front right below where the trackpad is goes from bright to dim. The apple is not lit up however. I don't know what to do... if I should go to the Apple store or if I should just get a new battery. My computer is about two years old and has done for as long as I remember. I don't know what to do, but I also don't want to screw anything up or erase anything by accident. Any advice would be appreicated.

  • Power-up and Going to Sleep Mystery

    I have a G5 iMac which has the following symptoms:
    1. It takes from 5 to 6 minutes to start up. It goes through all the normal processes --chime, apple on grey background, blue screen, etc.
    2. When I force-sleep, the G5 fan goes into "cyclone" mode and I have to force the power off.
    My G5 is operating 10.5.8 and everything seems to work - network, internet, email, Office, etc.
    Any ideas?
    -Bob

    For (1), try resetting PRAM.
    http://support.apple.com/kb/HT1379
    When it gets back to the Desktop, run System Preferences +Startup Disk+ pane. Make sure your internal drive is selected (highlighted) as the startup disk.
    For (2), try using the reset SMU procedure.
    http://support.apple.com/kb/HT1767
    You can also use +Repair Disk Permissions+ in Disk Utility as general maintenance, if it you have not done so recently.

  • Envy Pro 4-b000 Freezing up when on battery and going to sleep or closing the lid.

    Anyone else having issues with this?  I purchased 4 of these laptops and I have deployed 3 of them.  All 3 are doing the same thing.  HP support told me to reimage them back to factory... These laptops are a week old and have the factory image on them.  Wanted to know if anyone else is having the issue this is my first attempt at HP laptops in a long time and needless to say not impressed.  Trying to decide if I want to reimage or just return them and go back to what I know best... Dell... Any input would be appreciated.

    I think I have the same issue. I have an external display connected to my MacBook Pro. When I want the system to Sleep, I used to close the lid and everything was fine. Now that I have Lion installed, I close my lid and the system stays on and switches to my external display instead.
    This is annoying and hopefully someone figures out a fix soon. I hate having to manually put my system to sleep.

  • Imac high fan speed and goes to sleep 10sec after wake-up

    Hi,
    Since today my imac's fan speed is high (optical fan and cpu fan speed at: 4000rpm)
    Done a hardware test wich gives me 4SNS/1/40000001:IDSR-0.000 indicating something with logic board. According to istat all my temperatures are below 35°C (95°F). istat has readings for the cpu and optical drive temp (both around 26°C)
    On top of that if I put my imac to sleep after wakeup (give or take) 10sec later it would go to sleep again. tried the smc reset procedure. no success
    Any other tricks to try or just go for an exchange? (imac was bought on 2feb2010)

    I've had this problem since replacing the MLB in my iMac a few weeks ago. Initially brought in for repair when the CPU fan came on at 4k rpm and stayed on even after SMC reset and nvram reset. First replacement MLB was a dud, second corrected the fan problems. Now I'm having the sleep issue, I can't tie it to any particular process. Initially I thought it was graphics related as it would go to sleep during graphics intensive work, but yesterday it was doing it when just copying data to an external drive. The temperatures of the CPU and the GPU diode are within spec. I now use a fan controller to keep the CPU fan at 2100rpm and the HD fan at 2100rpm and I don't have the problem. From what I can tell now is that a sensor is incorrectly reporting temperatures intermittently. It may not be the MLB or the graphics card specifically, but the cable connecting the sensor to the board. I ran AHT after the last time it did this and it failed a sensor, but after running ASD on the machine it passed all the hardware. I'm bringing it back into my shop later this month and if i can remember i'll post here with the resolution, not much I can do at home beyond software diagnostics.

  • Mac Tower Pro  10.8.5 keeps going into sleep mode

    Purchased from Apple, refurbished 2012 Mac Tower Pro.  At the same time, purchased a new Dell U2713HM, 27" monitor.
    Have been operating on this new system since about the first week of December 2013.
    Issue:
    The computer has constantly gone into sleep mode after a few minutes of no activity.  I can have iTunes radio playing, but the system still goes into sleep mode.  As  I am typing and moving the curser, the machine stays awake.
    This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished.  It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
    BTW:  the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
    Solutions attempted:
    System Preferences — Energy Saver:  computer sleep and display sleep set to "never"  and unclicked the box "Put hard disks to sleep when possible." 
    Dell settings:  Turned off all energy savers.
    Results:
    Nothing.  Problem persists.

    I apologize for the angst.  The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost. 
    I misunderstood the terms of the warranty.  Thank you for your input and patience.  Much appreciated.  For the benefit of others that experience this with a new Mac that auto shuts down.  Check the following:
    1.  Go to System Preferences.
    2.  Click on Security and Privacy.
    3.  Click on Advanced  (bottom right corner)
    4.  If the first line is checked (Log out after 5 minutes of inactivity);  uncheck it and then click OK button.
    5.  Be sure to click the lock before existing Security and Privacy.
    Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

  • HP p6040d monitor going to sleep when starting

    Hi our desktop does not start anymore. Everytime I turn it on, monitor says "no signal", and goes to sleep.
    My sister suggested me to check the cables. I reconnect all the cables, and it turned on successfully. The next day, when we turn the pc on, it does the "no signal" again and goes to sleep. I checked the cables again, but this time it does not work.
    I don't have another monitor to check if this is a monitor/cpu issue. 
    By the way, the last 2-3 times I turn it on the cpu beeps(long beeps, for about 2 seconds each) multiple times. 
    What are your suggestions? Buy a new vga cord?
    This pc is not that old, it's just 4-5 years old.

    Any suggestions?

  • The screen goes into sleep during use

  • Goes into sleep mode

    I can be editing, surfing, burning a DVD. And all the sudden my MAc powers done and goes to sleep. I have my power saving set to 1 hour for all, so that's not it. It's very annoying when I am burning a DVD and it does that. i have to restart the burn.
    Can anyone help me with this. I've had this quad for 3 years now, it's just started doing that this year.
    HELP!!!

    Inside of mac is spotless. So, I don't think it's from overheating. Fans are running, they don't seem to be that load. definatley louded then my PC, but that's always the case since I got it. So they are probably running normal.
    This is getting very frustrating. It did it twice today. Is there anyway it could be a software issue?
    Need to sove this deperatly! It's affecting my work flow. I film and edit for a living. That's why I bought a Mac. i still have my old G4

  • How do you wake up a USB Keyboard plugged into MBP after it goes to sleep?

    Hello folks!
    I have a full sized USB (PC) Keyboard (Creative Spectre) plugged into my macbook pro for gaming and the use of the numeric keypad (which I honestly didn't realize I used that much until I didn't have one)...
    Anyway... when I first plug it in, everything is fine, but after the computer sits for a while and goes to sleep mode, I come back and have to wake it up.
    The funny thing is I can punch spacebar on the USB keyboard to wake up the macbook, but after that no other input is functioning. I have to unplug it and replug it back in for the keyboard to work again.
    Thanks in advance!

    Apparently not all usb keyboards are reliable for use on an MBP.
    Some posts suggest that those with extra proprietary functions may cause problems. One post suggests that MS usb keyboards operate more reliably than Logitech. Another post suggests that connecting a usb keyboard through a usb hub can cause a problem. These posts all relate to non-Apple usb keyboards.
    It would be wise to check with the manufacturer's website whether or not they rate their keyboard fully compatible with a Mac.
    The issues seem to be software related as regards the keyboard's firmware/drivers.
    Hope this gives some checks for you re compatibility.

  • Not giving warning before going to sleep

    I know there are lots of battery issues. I plan on replacing mine when I can get the funding.... My issue is that when I'm working on mine - no major power sucking applications just word or firefox - I'll have about 50% battery showing and then all of a sudden it just shuts down and goes to sleep. No low battery warning - nothing.
    do I need to recondition it? Or is it just dying and I have to face facts?

    Apple doesn't make its own batteries, so any battery you buy will be a third-party battery in some sense, even if it has an Apple label on it. Years ago, I direct-ordered a battery for an older Powerbook from Battery Technoloogy (BTI) that surprised me by arrriving with an Apple label and serial number on it, though it hadn't been advertised as an Apple battery. Perhaps BTI was manufacturing that particular battery for Apple. It can be nearly impossible to distinguish vendors from manufacturers without inside information that most of us don't have. So I wouldn't worry too much about anything other than capacity, price, and the manufacturer's and/or vendor's warranty and return policies.
