Macintosh World Community Grid Version <VER_NUM> Release Notes

http://worldcommunitygrid.org/

Installing World Community Grid may take several minutes; please be patient.

World Community Grid is an IBM philanthropic initiative that enables you to use your device to support scientific research. 

BOINC
World Community Grid is enabled by the Berkeley Open Infrastructure for Network Computing (BOINC) open source distributed computing platform.

New for Mojave: If your Mac has more than one user account, each user may see the following dialog upon their first login after you have installed World Community Grid: "World Community Grid_Finish_install" wants to control "System Events...." The World Community Grid installer needs this access to finish adding or removing its login item for each user; please click "OK".

GPU Processing
CUDA UPGRADE WARNING: Do not upgrade to CUDA 6.5 or later if you have an older NVIDIA GPU with Compute Capability 1.3 or less.  You can check your GPU’s Compute Capability at https://developer.nvidia.com/cuda-gpus. 

You can find older CUDA drivers at http://www.nvidia.com/object/mac-driver-archive.html. Note: after mounting the downloaded disk image, you may need to control-click on the CUDA installer package to open it.

For more options, please see the BOINC Macintosh administrator tools at:
http://boinc.berkeley.edu/wiki/Tools_for_Mac_OS_X

Processing with your graphics card, or GPU, is supported.  Please see http://boinc.berkeley.edu/wiki/GPU_computing for more information.   If you have a CUDA-capable NVIDIA GPU and you wish to run CUDA applications, you will need to download and install the CUDA driver and libraries for your system from http://www.nvidia.com/object/mac-driver-archive.html.  OpenCL applications on NVIDIA and ATI / AMD graphics processors are also supported.  OpenCL support is standard as part of Mac OS 10.6 and later.

Setting World Community Grid as your screen saver: This installer adds the World Community Grid screen saver to your system, and optionally changes your screen saver settings to use the World Community Grid screen saver.  You can also select World Community Grid as your screen saver later, using the screen saver settings in the System Preferences (accessible from the Apple menu).  

It may take a minute after the screen saver starts before the science application graphics appear.  

Note: on some versions of the Mac OS, you may not be able to exit the World Community Grid screen saver by moving the trackpad; you may need to press the trackpad or any key on the keyboard to exit.  

Security:

Security measures are in place to help protect your computer data from potential theft or accidental or malicious damage by limiting World Community Grid’s access to your system and data.  

For more information or technical details of the implementation, please see http://boinc.berkeley.edu/trac/wiki/SandboxUser and http://boinc.berkeley.edu/sandbox.php

Automatic start:

The installer sets World Community Grid as a Login item for all authorized users, not just the user who ran the installer.  You can add or remove Login Items by using the Users & Groups Pane in the System Preferences (accessible from the Apple menu).  

Other useful information:

The installer places two items onto your hard drive: “World Community Grid.app” in your /Applications folder and “World Community Grid.saver” in your /Library/Screen Savers folder.  

The installer creates the BOINC Data folder in your /Library/Application Support folder.  If you have previously been running World Community Grid in a different folder, copy your data into this folder before running the installer.  

All users who log in on the same Macintosh will share one set of BOINC Data, ensuring that work units are processed in the most timely manner.  

You can move (not copy) World Community Grid to any folder you wish on the same disk drive or partition.  If you do so, you will need to update the information in each user's Login Items.  In most cases, the World Community Grid screen saver should still work properly.  If it does not, move World Community Grid back to the /Applications folder.

To completely remove (uninstall) World Community Grid from your Macintosh, run the Uninstall World Community Grid application which is included with the installer in the extras folder.
