Playing AVI files (in fact not being able to play them)

Try and forget it's MS for the moment, my point is that it's used by the majority of trail cam makers and many other non MS entities and Apple is just making life difficult to make a point. Apple used to play avi files, they just stopped to be awkward. I use MS as main desktop and laptop, Apple for phone/pad and Linux occasionally. All are useful but all annoy me, the annoyance is mostly caused by issues such as this where they're all wanting the user to stick to their brand, it's not going to happen.

In other words NIH, not helpful.
