Yes, unfortunately there are lots of ways for an adversary to determine
the platform. For example differences in the font set, Intl formatting,
graphics rendering, Math functions. For now we have decided not to attempt
to conceal Mac vs Windows vs Linux, because it's too difficult and also
costly to usability.
