Screen goes to sleep when watching full screen video in browser

Hey,
On my MacBook Pro, with Mavericks, I often watch MLB.tv, WWE Network or even Youtube videos on full screen. Since upgrading to Mavericks, my screen goes to sleep after the normal amount of time based on my power settings in the system preferences. In previous versions of OS X, if i had a video on full screen, whether it was with Quicktime, VLC, Safari, Chrome, etc. the screen would never go to sleep.
Is there a way to prevent this from happening other than just changing how long it takes for the screen to time out?
Thanks.

I think you may want to point this out to Apple… it sounds like an oversight.

Can you set a 'hot corner' to disable the screensaver activation? It's less than ideal but it could save your sanity - just slide the cursor into the corner.
Hot corners should be available in the Desktop & Screensaver section of system preferences. I'm on another OS at present and may be mis-remebering an eariler OS feature.

Screen dimming & going to sleep when watching videos from websites

when clicking on a video from websites or from news readers (eg. Focus or Stern) this doesn’t prevent TP to dim the screen and even go to stand-by/sleep after the time set in the TP configuration. So you have to touch every now and then in order to keep it running.
Post relates to: HP TouchPad (WiFi)

yeah noticed this last night when being v lazy and watching a load of stuff in bed, kept having to tap the screen which would inadvertantly click some element of the app or webpage that launched the vid, could do with the dimmer not kicking in when video of any sort is being played.

My cursor does not disappear when watching full screen movies

I have a rMBP running Mountain Lion, everything is up to date. Like I said when watching full screen videos my cursor arrow does not dissapear. I am new to OSX so is this normal or do I have my settings set up wrong. Its not a huge deal, just getting more annoyed with each video, thanks for your help.

I have the same problem, but in addition, if the cursor doesn't disappear completely the video control menus stay glued to the bottom of the full screen. I may have to switch back to my pc to watch.....

MacBook Pro goes to sleep when copying files from attached drives

I have noticed that since installing Yosemite my MacBook Pro goes to sleep when it is in the middle of copying a large number of files. When I wake it up the copying continues.
I have also noticed that when I am watching videos from my shared iTunes library on an Apple TV the video will stop after about 15 minutes and the connection to the library is lost because the MacBook Pro has gone to sleep. When woken up then access to the library is restored but I need to reselect the movie and then resume.
I have changed the power saving options to do not let drives sleep when idle and do not sleep laptop.
Anyone else have any experience of this or better still a fix.
Thanks in advance.

I have just found that if I turn off the display sleep in the power settings then the problem is resolved. It means though that the screen on my MacBook Pro is on all the time albeit with a screen saver.

It goes to sleep, when I open it I cant click on anything.

When I close the lid or the macbook goes to sleep, when I open it I cant click on anything. The mouse moves but it doesnt let me close windows or do anything else either. I forced the programs to shut with cmd+alt+esc and it did let me to click on few things,however after the screen went to sleep again it did the same.Just didnt let me click on things.
Ive tried shutting the computer and rebooting it,even forced to it reboot itself and when it gets back the problem is still there.
My hardrive is fine,i run the cheks and I have 1/5 of the hardrive still in use.
However going over the activity (warning) log the following messages appeared during those freezes:
5.2.2013 19.10.57,756 System Preferences[225]: **** ERROR: *** -[ESGraphicsOptionsController _coreGetGraphicsStateForSelector:]: AGCGetMuxState() failed
Whats wrong? What can I do?

Hi Icemanjohn53,
Welcome to Apple Support Communities.
Take a look at the article linked below, it provides troubleshooting tips that can help you resolve the display issue with your iPhone 5.
Get help with the screen on your iPhone, iPad, or iPod touch - Apple Support
If your screen is too dim, too bright, or you see only faint images
Try to adjust the brightness. If the screen doesn’t respond when you adjust the brightness, open several apps to make sure it’s not an issue with only one app.
If you have a screen protector, try removing it. Try removing your case if it includes a screen protector.
If you see the issue in multiple apps, restart your device.
If restarting doesn’t fix the issue, restore your device.
If you still see the issue after you restore, contact Apple Support.
Cheers,

MBP 13" - Going to Sleep when moved

I have a new 13" MBP and I noticed last week that it just went to sleep when I lifted it off my lap and placed it on the table.
I was downloading an update at the time and also using iSquint to convert some video clips for my iPod so the machine was warm but hardly over stressed.
I tried to recreate this a few times afterwards and it seemed to work everytime I moved the MBP. I disable the Sudden Motion Sensor - cured it. Re-enabled the sensor and it seemed to stay cured until last night when I was doing the same thing again (Mac OS and Safari updates and iSquint).
It's not like these are particularly sudden movements that would be causing this.
Are they supposed to sleep if they get too hot? Could it just be overheating?
EDIT: I should just mention that since this has happened it's also become very unreliable with sleeping. It goes to sleep when it shouldn't and when I try to wake it I get a blank screen. Seems I have to open and close the lid a few times to get the screensaver logon box to appear again.

Try resetting your SMC for your specific model according to:

Why does my macbook pro "goes to sleep" when charging?

Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
I read from threads that it is a logic board problem....How do I solve this problem?

Try an SMC reset. Follow the method for "a battery you should not remove yourself."

Computer not going to sleep when lid closed

My wife's new MacBook Air has a couple of problems we can't figure out. First sometimes the computer is not going to sleep when lid is closed and when we lift the lid everything is frozen.
Second, the user Library folder is not seeable in her user account. I know it's there because on the side bar there's a short cut to Preferences folder which we can open.
Strange behavior.
Thanks,
Ron

Ron,
The user library folder (~/Library/) is hidden by default in Lion. I assume Apple doesn't want people mucking around with the sensitive files in there. So this is normal behavior.
As for the freezing issue, I would suggest you reset your power management and perform a safe boot to clear out caches. You should also see if the issue persists after disconnecting USB perhipherals.
Here's how:
Power Management:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Safe Boot:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

My Macbook Pro (5,3) sporadically goes to sleep when the lid is open and in use.

My Macbook Pro (5,3) sporadically goes to sleep when the lid is open and I am actively using it. This problem happens both with OS X 10.7.2 and Windows 7 (64bit), so I don't think it's an OS issue. Has anyone else encountered this? It's still covered under apple care... But I'd rather try to fix it myself before having to bring it in.
Thanks!

I wouldn't be surprised if this were the case - it does get hot. However, this happens even when I first open it after having it in sleep mode for an entire night... Do you know how to run the diag tool with OS X 10.7?

Why does that entire thread goes to sleep when we put a wait function in time critical loop?

Ujjval,
in a RT system, priorities have (in general) increased effect on the execution of the application.
It is recommended that you only have a single task in your RT program at "time critical". If you have two task "time critical" (that means you are running into issues caused by your quoted "feature"), you have a flaw in your application architecture.
Since LV 7.1, it is recommended to work with Timed Loops in order to prioritize tasks on a RT system. Timed Loops are executed on priorities between "time critical" and "above normal". Each Timed Loop will execute its content in a single thread in order to keep a good overview of the timing (like finished late [i-1]). Using those structures (and according settings) in a reasoned manner will prevent your RT system to run into priority issues.

You will have a real hard time to go into this very deep. This is the feature of LV: you can just use multithreading (multicores) without the needed knowledge of scheduling and load balancing. This makes LV programming in general very easy in comparison to e.g. ANSI C (in regard of multithreading). So creation of threads, distribution of tasks to the threads are abstracted and most often not visible to the programmer.
There are some switches and levers you can "play around" in order to make LV to behave differently in this matter. But this most often requires deep LV knowledge and cannot be explained in a simple posting.....
hope this helps,
Norbert
Amen to that!
The question can not be fully answered without digging into the internals of the OS LV is run on because LV works with the OS and lets it do the scheduling.
Yes that note applies to pre- LV 7 RT. When run under RT the ONE Time Critical loop was guarenteed to stay determinisitic.
Since then the Timed Loop was introduced that allowed multiple levels of priority and later allowed us to assign which CPU the code would run on.

Using NoSleep for MBP going to sleep when lid is closed

hy,
Is there any problem if I Use Nosleep (http://www.macupdate.com/app/mac/37991/nosleep) to keep my mac from going to sleep when lid is closed?

When watching youtube the video randomly jumps to the start of the video even if the cursor is not on the video.

When watching youtube the video randomly jumps to the start of the video even if the cursor is not on the video. This happens randomly and does not seem to be a problem with the videos as they run fine. what is going on?

Several times every day YouTube shuts down some of their servers to update stuff. Be patient if YouTube is slow, stuck or mangled. Transmissions from YouTube to your computer are done in multiple tiny packets of data and flash at a time. That's why sometimes you may get any of these scenarios: bits and pieces of text/thumbnails in weird places; sluggish loading/buffering; the spinning circle going on forever; or the player being blank. This problem could fix itself within a few hours or by the next day.
If your YouTube continues to behave slow, stuck or strange, it's very possible that your directories of "temporary internet files" and RAM (sometimes known as "cache") are close to the maximum and just cannot take anymore, the end result being any of the above scenarios or videos that: A) come to a complete freeze; B) start/stop/start/stop in a choppy way; or C) never even make it onto your screen.
"Temporary internet files" are tiny bits of webpages that get permanently put on your hard-drive. They will remain forever on your computer, gradually plugging it up like hair stuck in a sink drain, until you finally get rid of them once and for all. Thus, exit out of YouTube, then clear your "cache" of all its "temporary internet files", "cookies" and "history". It is best if you shutdown and reboot afterwards. You'll be amazed at how "fresh" and "new" your YouTube will be.

We have a solution that allows you to do most of what you want, including bulding the form, having people fill it out either in Reader (as an XFA-PDF) or on the iPad (as an HTML form).
You design the form once, and it will by styled correctly on the appropriate platform.

Screen goes to sleep when opened

Shortly after the install of Lion I started noticing that my screen goes into sleep mode or just shuts off completely after I open my macbook pro. I tried the general method of refreshing the screen of pressing the spacebar but that only worked for a week or two. Now I'm having to press "fn > F1 or F2" in order to get the screen to come back on. Any ideas on what's going on and how to fix it?

Simply install the upgrade, create a new disc with the new hardware drivers. Boot into Windows and install the new drivers from the newly burned CD.
For Boot Camp related troubleshooting post your problem in the Boot Camp forum.
For Windows problems try the Mac forums at the MicroSoft forums or pose the question in the Boot Camp forum.
If your Windows installation is corrupted you can try booting from the Windows installer and running the system repairs.
