Since I’ve been using the Mac OS now for around 20 years (started in Junior High), and since a lot of students and colleagues I know are just now jumping into the Mac pool, I tend to get a lot of questions about what “bells and whistles” they should install on their freshly opened Mac.  I’ve been keeping a scrap list over the last few months, so over the next few days I’ll highlight the Mac bells and whistles I just can’t live without.
