# Make a BOINC installation "secure" on a Macintosh with stand-alone BOINC Client
# The BOINC installer does this for a Macintosh installation with BOINC Manager;
# the BOINC Manager contains the BOINC client embedded in its bundle.
# if you ran the BOINC installer, you do not need to use this script unless you
# wish to run a separate copy of the stand-alone client in the BOINC Data
# directory.
#
# Create groups and users, set file/dir ownership and protection
#
# IMPORTANT NOTE: earlier versions of the Mac_SA_Insecure.sh and
# Mac_SA_Secure.sh scripts had serious problems when run under OS 10.3.x.
# They sometimes created bad users and groups with IDs that were duplicates
# of other users and groups. They ran correctly under OS 10.4.x
#
# If you ran an older version of either script under OS 10.3.x, you should
# first run the current version of Mac_SA_Insecure.sh to delete the bad
# entries and then run Mac_SA_Secure.sh to create new good entries.
#
#
# Execute this as root in the BOINC directory:
# cd {path_to_boinc_directory}
# sudo sh {path}/Mac_SA_Secure.sh
#
# Hint: you can enter the path to a directory or file by dragging its
# icon from the Finder onto the Terminal window.
#
# You must have already put all necessary files into the boinc directory,
# including the boinc client, boinc_cmd application, ca-bundle.crt, plus
# the switcher/ directory and its contents.
#
# This script also assumes that the user who runs it will be authorized
# to administer BOINC. For convenience in administering BOINC, this script
# adds the logged-in user to groups boinc_master and boinc_project
# (i.e., adds these groups to the user's supplementary groups list.)
#
# In addition, you should add any other users who will administer BOINC
# to groups boinc_master and boinc_project; e.g. for user mary:
#
# sudo dscl . -merge /groups/boinc_master users mary
# sudo dscl . -merge /groups/boinc_project users mary
#
# To remove user mary from group boinc_master:
# sudo dscl . -delete /groups/boinc_master users mary
#
# Last updated 1/17/08 for BOINC version 5.10.38
