North - your reaction is a common one and has been for 40+ years among
people who are used to (and generally happy with) a particular language
or operating system - and then move to a new and different one. Most
just bite the bullet, which is initially frustrating and confusing, but
ultimately pays off. Many of the problems stem from nomenclature, which
differs between the MAC and Intel (Windows) and other worlds. However,
the basic functions and objects and operations are very similar,
although called by different names. It might be helpful, if you can, to
spend a little time with someone familiar with both the MAC and the
Windows systems; a good translator-tutor can probably get you up to
speed fairly quickly.
People come to believe that what they're used to is The One True Way and
anything else is awkward and just plain wrong...and that's the major
reason for the quasi-theological battles between MAC and Windows
devotees. As it was a long time ago between fans of COBOL and FORTRAN.
As far as I know, Windows is the closest thing to MAC you'll find. Good
luck with whatever you choose to do. This is small comfort, I know.
