Mac in a Windows-only Workplace

Too generic of a question. What exactly do you need to do?

do you need to access files form a Windows server? Do you need to user a Windows Active directory?

Do you need to run Windows Apps?

You can always just run Windows on your Mac if you need to either through virtualization or Bootcamp.

Please be more specific as to what your question is. There is really no answer to the question as posed.
