I couldn't find a usable M-Wing, but solved it with Remote Pairs, Kite and XY-Chain.

Whatever that thing Dan is describing, it made the same eliminations as my XY-Chain.

[Note: I deleted mine and Marty's previous messages so that I could qualify my original comment.]

99.999% of the time, the W-Wing/M-Wing that I report in my puzzle is a substitute for an XY-Chain created in my puzzle generator logic. (The generator doesn't know about wings.)
