Mac OS X - switch off discrete GPU in apps

Hi - just quick one.
I have this program (WriteApp) which is quite cool, but every time I'm using it, it is automatically switching my mac into discrete graphics card mode. This app is not really into anything fancy/ high graphics dependent.
But when I launch Activity Monitor it is displayed as: "Requires High Perf GPU" - which means that my app spur the system to keep the advanced graphics processor active, and thereby drain battery life.

After some research ... I didn't find any solution apart using gfxCardStatus to permanently switch into "Integrated only" mode.

So ... there is a hack:
Open your app contents and inside them should be Info.plist file. Open it and add those 4 lines:

       <key>NSHighResolutionCapable</key>

       <true/>

<key>NSSupportsAutomaticGraphicsSwitching</key>

       <true/>

restart your app... and now - no more forcing into discrete mode.

Ubuntu 14.04 + apple time capsule

Finally got access to time capsule. 

1) install libraries:

sudo apt-get install libgcrypt11 libgcrypt11-dev libgmp3-dev readline-common libreadline6 libreadline6-dev libfuse2 libfuse-dev libncurses5-dev

2) download afpfs (link here)
3) unarchive afpfs ( tar -xzvf )
4) navigate to afpfs (cd afpfs*)
5) you will have to patch the afpfs because it has a bug in ubuntu 12.04 /13.04 and still in 14.04:

wget -O offset.diff https://bugzilla.redhat.com/attachment.cgi?id=397155 && patch -p1 < offset.diff

wget -O afpfs-ng-0.8.1-pointer.patchhttps://bugzilla.redhat.com/attachment.cgi?id=505576 && patch -p1 < afpfs-ng-0.8.1-pointer.patch

6) supposing you are in afpfs folder you archived:

sudo configure --prefix=/usr

sudo make install

7) now you should be able to connect to your timecapsule using this:

mkdir ~/capsule

8) Command for MOUNT: 

mount_afp afp://user:password@server_host_or_ip/Data ~/capsule

9)Command for UNMOUNT:

afp_client unmount ~/capsule

You should see a “capsule” folder in your home folder.
In my case Time Capsule stands on 10.0.1.1

Thanks to alex!
