# Mac_SA_Insecure.sh user group
#
# Undo making a Macintosh BOINC installation secure.  
# - Set file/dir ownership to the specified user and group
# - Remove BOINC groups and users
#
# 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_Insecure.sh user group
#
# After running this script, the boinc client must be run with 
# the --insecure option.
# NOTE: running BOINC with security disabled is not recommended.
#
