I would say that's a pretty uniformed statement.
Apple works at a pretty high level in certain industries.
ProRes as an example is used in every single top cinema camera in Hollywood, whether discussing ARRI, RED, Sony, Panasonic, etc. It's known to be one of the best compressed formats ever created; it has very easy playback (especially while editing multi-track), All-Intra, excellent compression, and zero generational loss. Most of those features other formats like h.265 and h.264, as an example, don't have. If something isn't shot on some form of propretary RAW in Hollywood, it's nearly a 100% chance that it's shot on ProRes. And I'll note that most of the time RAW isn't used except on things that are particularly high budget. I would say in general I see 12-bit ProRes 4444 being used way more often than ARRIRAW.
In the audio and recording industry, Logic is still one of the top NLE's (NLE's are mostly about user choice and also about genre. FL Studio, ProTools, and Ableton also all being popular with I would say a majority of users using Macs to run). Which has been used to record, and mix countless albums and also used as the back end to mix films and shows.
The Mac Pro is for no one else other than professionals. How many casual users spend $6000 starting on a machine (up to $80k)? Or $5000 on a display? No one is buying a $4000 Mac Studio to work in iMovie, or as DukeNukemX brings up constantly: "to play games". This hardware is very specifically targeted at editing and grading houses, and VFX/SFX devs.
There are plenty of other people that use the CPU and graphical performance with MacOS software to do plenty of other things that don't necessarily relate to the Audio/Visual realm - that's just the industry I'm in and know best. But chances are whatever your favorite music is and whatever shows and movies you like were all edited on a Mac.
I was there when Apple stopped going to NAB, when they pulled FCP 7 *off the shelves* when they killed their servers and broadcast storage. FCP Server. Shake. Color. The 17" Macbook. When the new Mac Pro was the trashcan. When Apps stopped going full screen across multiple displays. When they made Nvidia the bastard child. When the iMacs stopped supporting jumbo frames on their NICs. When they straight refused to acknowledge 10 Bit displays for a decade.
ProRes pre-dates their turn against Pro's. In all the channels I have built systems and workflows for nobody has used ProRes except for dallies because its way to hard to render to it. And everyone's using RAW all over the place. Who the hell is buying a Mac Pro to edit on in 2022? If you build an Apple shop you are just begging to get your knees shot out. Again.
Apple is coasting on people who are die hards. The type who paid for the rack mounts for the trashcans.
Come on dude. There is a reason we all bench test in Resolve instead of FCP X.
