If they could throw in a database application, that would help. Mac users don't have Access but they do have Filemaker Pro. Mac OSX does come with very good programs and that's partly why Apple machines have been more expensive than PCs. The choice of software available is limited but what's installed is more than enough for most people's needs.
MySQL is another good database than runs on Macs. Mac OS X includes the Apache web server and PHP with extensions to support MySQL.
