It really felt like the best platform. I had a nice G4 tower, and eventually used a G5 and then Mac Pro tower. Things generally just worked, and you could expand things as needed.
Roll around to today, and it's a mess. Apple canceled a lot of their pro products. Aperture? Dead. Final Cut got nerfed pretty hard. Logic is still reasonably well maintained, but Ableton Live took over a lot for me.
The hardware options aren't that great right now for my needs. Last week, I sold my 2011 Macbook Pro to a friend and switched all my audio stuff to my old Windows gaming system. Picked up a Firewire PCI-E card for $20 and I was in business. It's fast, has a ton of ram and is easily expandable. Windows 10 drives me nuts, but eh...
I've still got three Macbook Pros for software development, and they are pretty great for that (minus the new keyboard, and that Tensorflow GPU has dropped OS X support). I don't think I'll be switching laptops anytime soon. But ugh, audio work on them just feels like an overpriced joke at this point.
I really never thought I'd be saying it, but for photography and audio stuff, Windows seems to be the place right now!
