I would concur. You can record high quality encoded audio on your iPhone, audio design on your iPad with your other samples, and add the mixed soundscape into your film on iMac.

I literally know someone in the media industry who’s whole effortless workflow is what makes him a go-to guy for quick and flexible turnaround for audio mastery for films. He works exclusively on apple devices for this exact reason.

I’m not saying it’s impossible another way, but he really likes the ecosystem.

At this point I’d call it more of a legacy approach - they definitely still control the space, but the workflow is quite easily accomplished on other systems.

I’d also add many (SO MANY) of the pro audio and video systems out there are also running Linux, so even with sa mac-focused workflow, many of the pros out there are using Linux (often without any clue that they are).

So to me its similar to Windows on the desktop - its not necessarily the best option in all cases, but its often the path of least resistance. As a result, pretty much all of them buy into an Apple ecosystem from the get-go.
