Flash on Mavericks (App Nap)

Hello,
How ya'll doing?
I'm having a little issue after I upgraded to Mavericks. All works superb and I love it, but Adobe Flash.
I play an online game that runs on top of flash and the performance is superb compared to ML, but one thing keeps bothering me. If I stop typing or moving my mouse, the flash window will 'stop', 'freeze', to save battery probable (app nap, perhaps?) and this will make my character disconnect from the game.
It's really annoying, as it's a game where it's quite common to just click on the map and let the character go to the desired location for a couple of minutes or maybe entering a safe zone while I make myself a cuppa tea.
I tried entering Safari's advanced menu and disabling the option "Stop plug-ins to save power" and it changed nothing. If I stop styping or using the mouse, the game will freeze in a matter of seconds. If I do any action on the computer, the game resume normally, but with the character kicked out.
There is any way to prevent Mavericks from putting my flash game client on this sleep mode?

Hi ...
Try this ..
Open System Preferences > Flash Player then select the Advanced tab.
Click Delete All under Browsing Data and Settings
Not empty the Safari cache.
From your Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now click Develop from the menu bar. From the drop down menu click Empty Caches.
Now try a game.

Disabling Mac OS X Mavericks "App Nap"

Does anyone have any ideas how to defeat the new Mavericks App Nap feature? http://www.apple.com/osx/advanced-technologies/ I have an application that can't go to sleep on the job.
It is easy enough to disable it on my own machine using the "Prevent App Nap" checkbox in Get Info on a given *.app executable. What I need to do is disable it for stand-alone executable installed on customer Macs. Checking the checkbox on my computer before distributing it to other computer is not good enough--Maverick resets the checkbox whenever the *.app is copied to another Mac. I have searched for a info.plist key to do the job, but I haven't been able to find one.
I'm trying to avoid giving customers instructions for disabling App Nap. Any ideas on how to disable the feature for deployed apps? Or is there anything I can put in the app (short of generating sound) that would defeat it?
Thanks.

I would look into using the System Exec VI and sending the following command:
defaults write <app domain name> NSAppSleepDisabled -bool YES
This should programmatically disable the App Nap feature in Mavericks. I used this as a reference for the command.

Mavericks and APP NAP

I have tried everything I know to stop APP NAP. it kills everything I do on the mac... I have checked the prevent app nap box, i have tried the terminal I also reloaded Mavericks and still it does what it wants to... I contacted apple the they dont give a ratsazz there reponse is, contact the creater of the other services and make them fix it...... any solutions before I sell off my MAC computers??

If you're interested in posting some additional details of the application(s) and of what's happening with the processes around app nap or whatever is happening, then somebody here might recognize what's going on.
If the Finder ⌘I "Get Info" path to disable App Nap doesn't prevent App Nap for the particular application, then there's an OS X bug. Apple Support has probably already led you through this sequence, so it would seem that there's either an OS X bug lurking or there's something else going on with the particular application(s) in use, or there's possibly an application bug or application incompatibility with 10.9 Mavericks.
You're quite right, too. Should the particular application(s) and/or OS X no longer provide your computing requirements, then a platform migration is certainly expected and appropriate.

Sounds are paused in OSX Mavericks, usually in Safari. App Nap?

Hi guys,
For the past time I have been noticing strange behavior on my MBPr (13", Late 2012, i5 2.5Ghz, 8GB RAM) running on 10.9.3 (Mavericks). It seems like sounds are being held back. It usually happens when sounds are played in a non-active tab in Safari (I don't use other browsers unless I need it for testing or when a site/webapp requires Chrome or Firefox, so I can't confirm any such behavior in other browsers). What happens, for example, is that I recieve messages on Facebook (which are displayed as notifications in OSX). Sometimes I recieve messages from multiple users. If I then switch tabs to Facebook a few minutes later, I hear the "new message" sound from Facebook multiple times in a row, once for each message recieved.
Another example is from a few weeks back. There is a website in the Netherlands called iBood (it's in other European countries too). Once in a while they have a so-called "iBood hunt". What happens is that they offer a single product at a time at a really attractive price (usually) but the products usually sell out within a minute. When a product sells out a new product is displayed. There is a third-party website that offers a auto-refresher (http://iboodhunt.1dagskoopjes.nl). Whenever a product sells out the website produces a *boink* sound, when a new product is available a *ding ding* bell sound is played. However, If I open the page during a hunt and switch to a different tab, all goes quiet. If I then switch back to the tab I get a flashflood of sound: *ding ding* *ding ding* *ding ding* *boink* boink*. This effectively destroys the purpose of the sounds which are supposed to alert me when a new product is placed so I can quickly look if the offer interests me, but I don't need to stare at the tab the whole time, allowing me to do other things in the mean time.
However, today I observed similar behaviour, except it wasn't in a closed tab. This morning I had sent an e-mail with Mail. A few hours later ( ! ) I plugged in my headphones to listen to some music. As soon as I plugged in my headphones, with Mail running in the background but not open (CMD+W'ed), I all of a sudden heard the "finnished checking for mail" sound a couple of times in a row and then the "flying away airplane" sound you hear when you have sent an email.
I'm guessing that this behavior is being caused by some/one of the power saving features in Mavericks. I don't want to deactivate app nap for a whole bunch of apps on my computer just to not have lag in my sounds. I was wondering if more people have experienced such behavior and if they have found any fix?
Cheers

Problems with Icons flashing after Maverick Install

Just installed Mavericks--now my icons flash randomly and repeatedly as if the desktop keeps reloading. Imessage (AIM) crashed today as well. Anyone else having this issue or could suggest a fix? I have applecare and I will call them if needed but if it's something simple like deleting a plist, I would rather avoid a prolonged phone call. I did run disk utlity and fixed the permissions, don't see anything unusual running on the activity monitor (though I'm not so familiar with what should be). Thanks in advance for your help!

Do you have Google Drive installed? Other users have reported the same behavior and found that uninstalling Google Drive resolves it. Presumably they are working on a fix.
Other users have found that disabling App Nap for Google Drive resolves it. Do this by selecting the Google Drive application in a Finder window, and Get Info for it (File menu > Get Info.) Next under General make sure the Prevent App Nap checkbox is checked.
Best of luck.

How to enable app nap?

When I check Activity Monitor, the majority of my apps show "No" for App Nap (although I never disabled them) -- is there a way to enable all those apps?

Yes, exactly so.
from Foundation Release Notes for OS X v10.9
The greatest benefit to the user comes when every application on their system is doing as little work as possible. Therefore, App Nap is an opt-out feature. The user can opt an application out of App Nap manually with a checkbox in the Finder “Get Info...” pane. Developers can temporarily opt an application out by bracketing user-initiated activities with new NSProcessInfo API. Please consider the power usage of your application before opting out of App Nap.
from What's New in OS X: OS X Mavericks v10.9
App Nap
App Nap reduces power consumption by completely suspending your app’s execution when it meets certain criteria. This ensures that your app does not periodically wake up to do unnecessary work. An app is considered to be a candidate for sleep if:
It is not visible—if all of an app’s windows are either hidden by other windows or minimized in a hidden dock, and the app is not in the foreground
It is not audible
It has not explicitly disabled automatic termination
It has not taken any power management assertions
When all of these conditions are met, OS X may put the app to sleep. While asleep, the app is placed on a scheduling queue that rarely gets actual time on the CPU.
The app wakes up automatically when the user brings the app to the foreground or when the app receives a Mach message or Apple event.

Turning off App Nap is not fixing my FCP rendering issue

I noticed that Mavericks was killing my rendering in FCP. I like to let it run overnight, and it was simply shutting off.
I did some research and learned about app nap, and how it was shutting down my rendering.
I went to finder, found FCP, and disabled app nap... but I'm STILL having problems with the rendering. It just stops! This is adding days and days to my production time, and I don't know how to fix it.
This is really really throwing a cramp in my work, and I'm really not please with apple for this one.

I switched MacBooks to complete my rendering... I will set up a new project tonight and let you know if adjusting these settings helped.
That said... I have to NEVER allow my computer to sleep, just so this rendering can take place? That's a little bit absurd.

App Nap Running on early 2008 iMac

My understanding was that App Nap couldn't run on an early 2008 desktop iMac?
Yet, the Energy tab in Activity Monitor from time to time shows App Nap as active for the Finder!
If this is true, it might explain some of the sluggishness of my iMac since installing Mavericks ... ?
Larry

All the Intel iMacs have the same procedure, as far as I know.
http://support.apple.com/kb/HT1543
Without specifically mentioning "SMC," this procedure (below) is in the trouble-shooting section of the +early 2008+ iMac's little printed manual
"Unplug the power cord and wait at least 30 seconds. Plug the power cord back in
and press the power button again to start up your iMac."

"prevent app nap" gone?

call me crazy but in mavericks there was a checkbox called "prevent app nap" available on some apps, available when you do a cmd+i (or "get info"). I used it on a few citrix programs. i have OS X 10.10.1 and don't see that option. I checked a few other apps, even apple apps, and i don't see the option anymore. can anyone confirm whether or not this checkbook was removed/changed in Yosemite?

What if it's not managed automatically? My spotify started stuttering since I upgraded to yosemite. Preventing app nap for spotify solved it. Now after updating spotify it is stuttering again. And I can't prevent it from app naping. Any way to solve this?

Creating a Mavericks USB boot drive after the horse has bolted. Can I create a bootable USB drive from my iMac after installing Mavericks without saving the Install OS X Mavericks.app file? Do I need to re- download the whole 5.29 Gb again?

Creating a Mavericks USB boot drive after the horse has bolted. Can I create a bootable USB drive from my iMac after installing Mavericks without saving the Install OS X Mavericks.app file? Do I need to re- download the whole 5.29 Gb from the App Store again? My problem is my 4Gb/month allowance on a 12 month contract. I cannot purchase a data block from my ISP and although my speed is theoretically slowed to 64k after reaching my 4Gb, it actually ceases to download in reality.

HI tasclix, it depends what you mean by an OS X boot drive.
If you want a recovery disk from which you can reinstall (by re-downloading) or recover from a time machine backup, then nbar is correct.
If, however, you want to boot and run the OS X installer from the USB drive (so that you don't need to download again), then you will need a copy of "Install OS X Mavericks.app"; see this article:
http://support.apple.com/kb/HT5856
Before downloading again, search your system to see if the installer is still there - it's usually in the /Applications folder unless it has been deleted, but check your whole system for it anyway, you never know, you might still have it somewhere.

How to disable App Nap in latest MacOS by default?

As mentioned in AIR 3.9 release AIR now supports App Nap feature in latest MacOS (http://forums.adobe.com/message/5745066); but I'm not able to found any documentation on whether AIR provides any in-build feature/code to enable/disable App Nap while compiling or not. Is this an application behavior feature that AIR now supports, or AIR is providing any way to enable/disable this feature while compiling?
Thanks!

Can anybody suggest on this? We want to support 'prevent app nap' by default through our binaries. Please, suggest.

Is Mavericks.app for iMac same as that for Macbook Air?

I downloaded Mavericks.app for my iMac and then used the same installer (mavericks.app) to upgrade my Macbook Air 2013. The upgrade was smooth; but the battery life isn't very great.
Can someone confirm that there's Mavericks upgrade for iMac is the same as that for Macbook Air?

Thanks! Haven't had any problems with the software; except that I'm not happy with the battery life my MBA 2013, 13" offers after the upgrade. Looks like time to reset PRAM and SMC.

I have an Ipod touch. Since this morning I am not able to open any of my purchased apps. The screen briefly flashes but the apps don't start. Can anyone help?

- Try resetting the iPod. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Then download/install new app.

Transition from my firefox extension to a Flash Builder desktop app

Trying to make a slow transistion from my firefox extension to a Flash Builder desktop app.
Okay i'm not familiar on how to go about this I have js code that lets my app sync it self with the lates build it looks for a new version number which is in a txt file. Inside the txt file I have 0.0.0 so evertime I change the version number to 0.0.1. The app checks for new updates and sees the txt file has a new version number and start to pull in the zip file and extrudes the zip into the directory.
I can't get my head around on how to modify this code ["@mozilla.org/extensions/manager;1"].getService
to look in the root directory of my Flash Builder app.
function Xcalibur_Sync(){
    document.documentElement.getButton("accept").disabled = true;
    var Cc = Components.classes;
    var Ci = Components.interfaces;
    var url = xcaliburGetUnicharPref("extensions.xcalibur.downloadurl");
    var Step1 = document.getElementById("xcalStep1");
    var Step1done = document.getElementById("xcalStep1Done");
    var Step2 = document.getElementById("xcalStep2");
    var Step2done = document.getElementById("xcalStep2Done");
    var Step3 = document.getElementById("xcalStep3");
    var Step3done = document.getElementById("xcalStep3Done");
    var Step4 = document.getElementById("xcalStep4");
    var Step4done = document.getElementById("xcalStep4Done");
    var xcalSyncDone = document.getElementById("xcalSyncDone");
    var progressMeter = document.getElementById("xcalProgressMeter");
    var progressPct = document.getElementById("xcalProgressPct");
// Get Xcalibur version and location
    var GUID = "[email protected]"
    var gExtensionManager = Cc["@mozilla.org/extensions/manager;1"].getService(Ci.nsIExtensionManager);
//var currentVersion = gExtensionManager.getItemForID(GUID).version;
    var currentVersion = xcaliburPrefs.getCharPref("extensions.xcalibur.installedversion");
    var xcaliburdir = gExtensionManager.getInstallLocation(GUID).getItemLocation(GUID);
    var file = Cc["@mozilla.org/file/local;1"].createInstance(Ci.nsILocalFile);
    file.initWithPath(xcaliburdir.path);
    //Step 1 - See if an update is available
    Step1.setAttribute("hidden", "false");
    var req = new XMLHttpRequest();
    req.open('GET', url+"CRV.txt", false);
    try{
        req.send(null);
    }catch(e){
        alert("Cannot get update information from "+url+"CRV.txt\n"+e.toString()+"\n\nSync aborted ...");
        window.close();
        return false;
    }//try
    if(req.status == 200){
        var CRV = req.responseText;
Any Ideas?
Thanks,

Have you taken a look at the documentation on updating AIR applications?
http://help.adobe.com/en_US/AIR/1.5/devappsflex/WS5b3ccc516d4fbf351e63e3d118666ade46-7ff2. html
Or is it something else you wish to do? You can access the directory where your app is installed by looking at File.applicationDirectory and you can hit a URL by using URLRequest.
