Everything else works flawlessly, but fply.dylib (md5=9831e5c61ed5f8f0db1495a73a1ea785) does not work. (DMG is from 2014)I fixed it by extracting fply.dylib from a March 15, 2015 snapshot of the cloudfront Mirroring360 dmg:

The one from 2015 works flawlessly in airplaying an iOS 8.4.1 iPad mini 1.

I submitted a PR: #15 with this fix, just putting it out here for the record.
Works perfectly with that fix, iOS 8.4.1.
