Built-in Chess app stresses CPU

I have just upgraded my MacBook Pro Mid-2012 to Mountain Lion. When playing chess sjeng.ChessEngine uses 100% of CPU sometimes and doesnt go down. I had chess in background and I was confused why my Macbook is so hot, and then I checked the activity monitor and it showed 2 x sjeng.ChessEngine running on 100% each.
Thank you.

Hi,
i think you will find this thread of interest, it explains why certain games can use the whole CPU.

  • Podcasts won't sync to the podcast portion of the built in Music App on my iPod Touch.  How do I fix this?

    Ever since I downloaded the new Apple Podcast App my Podcasts that I subscribe to in iTunes have not worked correctly.   I have deleted the Apple Podcast App because it does not work well and I'd rather have the functionality with Podcasts that the sync from iTunes to the built in Music App has.  However, now I can't get the podcasts I subscribe to to show up in the original app.  My iTunes says that all the podcasts are being synced and it is checked to sync them and even the data storage indicator bar at the bottom shows the amount of space being taken up as if the podcasts did sync but when I go into my iPod Touch in the music app they are not there.  How do I fix this?  Thanks!

    What you're really doing is trying to create a new icloud account using an ID that is not currently associated with a user's account.  A device can only do this a fixed number of times (3 or 5, don't remember), after which you must use a different device or computer to create the account.

  • My laptop has a webcam but no built in webcam app.

    I have to use a crappy software to take pictures. How do I fix this? I need a webcam app that has a timer and I was hoping that there'd a be built in webcam app on my laptop that would do the trick. But there's no app in the first place.
    Help.

    Hi,
    Unless you've removed it, the webcam software should hae a software/app called CyberLink Youcam. You can dwnload from the following link and install on your computer again:

  • IPad to AppleTV sound only - built in Video App

    I used to be able to airplay from my ipad to my appletv but now only sound plays, no video. I have made sure my iPad and AppleTV (latest version) are all running up to date software.
    I am trying to play via the built in Video app on the iPad , not a third party app.
    This used to work.
    How can I get it working again.  I've also tried restarting the Apple TV and the iPad multiple times - didn't help

    My router is an Airport Extreme. It's a Walking Dead Episode I bought on iTunes.
    I worked at Apple in Core OS doing Mac OS X kernel development for 21 years so I know something about Apple products.  This is some kind of bug and not ''user error''
    I can occasionally get it to play a video by constantly trying over and over again and also restarting my ipad and appletv - there is no rhyme or reason as to when it will actually play and episode. And then the next time I try it will just do the sound again.
    This did not used to happen - probably 2-3 months ago it would play 100% of the time
    Really annoying.

  • I have a purchased version Chess (from Apple) on my old iPod. Today I got a new Gen. 5 iPod. HOW can I get the chess app onto the new iPod, or do I have to purchase it again?

    I have a purchased version of Chess (from Apple) on my old iPod. Today I got a new Gen. 5 iPod. HOW can I get the chess app onto the new iPod, or do I have to purchase it again?

    Either sync it from your iTunes library or redownload it directly to the iPod by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store         

  • Is there a way to prohibit use of Apple's built in iPad apps, using Configurator?

    We have a number of iPads in our school, and I'm looking for a way to disable use of things like iChat.  Is there a way to disable the built in Apple Apps?

    I was prepared to say that you can't block or circumvent the default iOS apps, and then I read your response. Assuming you have control of the iOS device before the user so you can make such a configuration change, that sounds like an innovative and viable solution. I'll have to look into that.
    Configurator is fairly impressive for a simple tool, though. I read this piece recently which outlines five essential elements of an MDM solution, and it seems like Configurator meets at least some of them. For more about, check out my about.me profile.

  • The built-in "Notes" apps in my ipad2 wont open, when i click it immedieately it closes...help!

    The built-in "Notes" apps in my ipad2 wont open, when i click it immedieately it closes...help!... Thanks

    Try rebooting the iPad by pressing and holding the on/off and home buttons simultaneously until the screen goes blank and you see the apple logo. It should take about 10-15 seconds to reboot. This should clear out whatever is hanging the app.

  • Microphone doesn't seem to work on iPhone4 for Built-in Photo App for Video recording

    I have an iPhone4 and I used the built-in Photo app to record a video. When I played it back on the iPhone or on my Computer I heard no sound! I used the built in Voice Recoder and I could record and play back voice memos! Any idea of the fix?

    i had the same problem.
    try this. when you press go live and the chat thing comes up, right click on where your video is supposed to show up and then press settings then click on the tab with the picture of a webcam. then press the drop down box and select usb video.
    it should work.

  • Built-in contacts app missing

    I set up my Sports Watch 42mm Space Grey on Monday, but I can't find the built-in contacts app anymore on the app screen:
    I can still see it in the iPhone Watch app listed under "My Watch" and change it's settings, but I can't get it to show. I know I deleted a bunch of apps from the watch by pressing their "x" their, so I maybe I deleted the contacts app as well.
    How do I get it back?
    Regards,
    Karsten Silz

    Hi,
    There is no contacts app for the Apple Watch which is why you cannot see it.
    You can set your twelve friends for ease of access using the side button.
    It is possible to view your contacts list from within the message and phone apps.
    The contacts icon/ option is only in the Apple Watch app so you switch between mirroring your iPhone contacts or setting it to custom for the message and phone apps.
    Regards

  • Being redirected to built in FB app while trying to use www FB on Pre

    I have been using the full www FB on my Pre happily for months with no problems. Just today when I type the URL it redirects me to the built in FB app. I've cleared cache/history and restarted several times and even removed the bookmark. I hate the built in FB because it's so buggy and I don't like the FB app from the app catalog or mobile version. What else can I do? I haven't had any problems with this until this morning.

    Hello and welcome to the forums;
    When you navigate to Facebook, Google, and several other websites, the site recognizes you are browsing on a mobile device, and attempts to helpfully redirect you to the mobile version of their webpage. For Google, the solution is to choose "classic" instead of "mobile" at the bottom of the screen. For Facebook, it took me a while to find an address that Facebook would allow to access the full version of their website:
    facebook.com/home.php
    This should get you there, and I recommend creating a bookmark for that site to avoid typing in the full thing each time.
    Hope this helps,

  • On PowerBook G4 OS 10.5.8 my chess App tells me "You can't open the app 'chess' because it is not supported on this architecture. It has worked before. What does that means? What can I do to get it working?

    On PowerBook G4 OS 10.5.8 my chess App tells me "You can't open the app 'chess' because it is not supported on this architecture. It has worked before. What does that means? What can I do to get it working?

    It sounds like you might have accidently copied Chess over from an Intel Mac, or an Intel Mac's installer DVD.  The architecture typically means it is designed uniquely for either Intel or PowerPC.  Be sure to extract Chess from the 10.5 Retail installer disc that looks like * and not any other disk.  http://www.charlessoft.com/ 's Pacifist lets you extract individual applications from installers without having to reinstall everything.
