How can an applicant know in advance if the position involves an OS they won't be willing to use?
This seems like a case where clear communication in both directions is desirable. You as a hiring manager should disclose if a particular OS is required, so the applicant can tell you if that's acceptable or not.
(Maybe you personally do this -- I'm really using a generic "you" in this comment.)
