# 30th March 2010:
|
||
# Added a check to make sure user is in the staff group. This was a problem
|
||
# for me, and I think it was due to me migrating my account over several
|
||
# versions of OS X. I cannot verify that for sure, and it was tested on
|
||
# 10.6.2 using the Directory Service command line utility and my laptop.
|
||
#
|
||
# My assumptions are:
|
||
# - you are running OS X 10.6.x
|
||
# - your machine is not managed as part of a group using networked
|
||
# Directory Services
|
||
# - you have not recently killed any baby seals or kittens
