# Script to set up Macintosh to run BOINC client as a daemon / service
# by Charlie Fenton 7/26/06 
# revised 1/6/08 to use launchd
##
## Note: this version of this script requires BOINC 5.10.34 or later 
## and OS 10.4 or later.  
##

## Usage:
##
## source Make_BOINC_Service.sh [path_to_client_dir] [path_to_data_dir]
##
## path_to_client_dir is needed only for stand-alone client or if Manager
##  is at non-standard location.
##
## path_to_data_dir is needed only for stand-alone client when data is in 
##  a different directory than the client.
##
## Directions for use:
##
## (1) Install BOINC Manager using the BOINC.pkg Installer Package, or 
##     install stand-alone client. 
## (2) Make sure you are logged in as a user with administrator 
##     privileges.
## (3) Run the Terminal application.
## (4) In the Terminal window, type "source" and a space.
## (5) Drag this script file from the Finder into the Terminal window.
## (6) If using the stand-alone client, or if the Manager is in a non-
##     standard location, drag the folder containing the client from 
##     the Finder into the Terminal window (or type the path excluding 
##     the trailing slash).
## (7) If using the stand-alone client, but the client is not in the data 
##     directory, drag the BOINC data folder from the Finder into the 
##     Terminal window (or type the path excluding the trailing slash).
## (8) Press the return key.
## (9) When prompted, enter your administrator password.
## (10) Restart the computer.
##
## The system will now start BOINC client as a daemon / service at 
## system startup.  You will still be able to control and monitor BOINC 
## using the BOINC Manager, but BOINC client will remain running after 
## you quit BOINC Manager, when the ScreenSaver quits, and even when 
## no user is logged in.
##
## Note: the BOINC ScreenSaver may not display graphics for some users 
## when BOINC Client is running as a daemon / service.  Thus will be 
## fixed with the release of BOINC 6.0 and project applications updated
## to use the BOINC 6 graphics API.
##

##
## When the system has launched BOINC Client as a daemon, you can stop the 
## BOINC Client from the Terminal by typing:
##   sudo launchctl stop edu.berkeley.boinc
## and you can restart the BOINC Client from the Terminal by typing:
##   sudo launchctl start edu.berkeley.boinc
##
## Note: The BOINC Client will quit immediately after launch if it detects 
## another instance of BOINC Client already running.  So these launchctl 
## commands will fail if the BOINC Client was started by the BOINC Manager 
## or ScreenSaver.
##
## If BOINC Client is not already running when the BOINC Manager is launched, 
## the Manager will start BOINC Client.  This will happen automatically at 
## login if you have BOINC Manager set as a login item for that user.  If 
## it was started by the Manager, then BOINC Client will quit when the BOINC 
## Manager quits.
##
## If BOINC Client is not already running when the BOINC ScreenSaver starts, 
## the ScreenSaver will start BOINC Client and will quit BOINC Client when 
## the ScreenSaver is dismissed.
##

## REMOVAL:
## To undo the effects of this script (i.e., to permanently stop running BOINC 
## as a daemon / service):
## (1) In the Finder, browse to the /Library/LaunchDaemons folder.
## (2) Drag the file edu.berkeley.boinc.plist to the trash.  (Finder will ask 
##     for your administrator user name and password).
## (3) Restart the computer.
##
## The system will no longer start BOINC client as a daemon / service 
## at system startup.   
##
## If you wish to completely remove BOINC from your computer, first 
## complete the above steps, then follow the directions in the web 
## page http://boinc.berkeley.edu/mac_advanced.php or in the README.rtf 
## file supplied with the BOINC installer.
