From another Feb 20 2014 interview with Yoshi-P, this time on Famitsu's site, translation by Reinheart (as ever, it's greatly appreciated):
F: OK, how about releasing for the Mac version?

Y: For the OS itself it’s gaining popularity, as well as other MMO makers are starting to look into Mac version as well, so we also are talking with staffs about starting to look into this.
I'm really happy to see these articles address the issue directly. SE's presentation and these direct quotes from Yoshi-P came within days of the start of this thread.
