I made the switch from Windows to Mac about… 12-14 years ago? Happy to share my experiences.
I’ll start by saying I suspect a lot of the differences here are legacy - way back in the day, Macs were hands down the best option for ANY multimedia work, from publishing and design layout to music production, in part because the programs Mac was producing were just better. Today, I’m not really sure how true that is, especially because even professional high end audio production is not nearly as resource intensive as something like video, and especially generative AI video, processing.
But, your pro column, today, is that Macs just work. Until they don’t and then you’re probably looking at trip to the Apple store for repair (I had a video card fail on mine), but because Apple keeps such a tight rein on their ecosystem, everything plays together really well, compatibility is never an issue, and everything is pretty much flawless right p to the (rare) point of component failure. And, upside #2, they’re tanks. My iMac is… a 2011, I think, and I still record and mix on it with no problem at all. I added more RAM at some point along the way, but it’s a 13 year old desktop and I’ve thrown some pretty intense mixes at it (in the demoing phase, often with 8+ instances of amp VSTs in 8x oversampling mode at 88.2 24 bit) and it doesn’t so much as blink, running Reaper. I’m going to have to upgrade in the next year or two, I think, but mostly because the newest version of Reaper isn’t compatible with the latest version of MacOS I can run on my machine. Performance has not been the issue, at all.
There’s also a lot of cool inter-operability with Macs if you use other apple products - I’m sure Windows has done something similar by now, but for example the fact that you can run Messenger on your computer in sync with your phone so you can text from both your phone and your computer if you own an iphone, little touches like that. Sharing fles from one ot the other, or links between phone and computer, is effortless too. Again, Windows has probably developed something similar, but that was one of the first “whoah! cool!” moments for me when I got a Mac.
Downsides, well… One, it’s a learning curve. If you’re used to Windows, it’s not that MacOS is SO different, but it’s different ENOUGH that it’ll confuse you a little for the first few months. These days I go back and forth pretty effortlessly between a Windows machine at work and a Mac at home, but it’ll be dizzying at first. and you WILL want a mouse with left/right click compatibility, if you’re looking at a laptop.
The bigger one I found though that I wasn’t expecting was compatibility - when I switched, I had a pretty good suite of freeware plugins that I’d been using that I was pretty happy with, and started configuring Reaper and downloading stuff, and realized that a whole bunch of them were PC only. Everyone talks about how virus-resistant macs are, and a lot of that is because of how much more of the market is PC so that’s a more lucrative target… but you also run into the downside of that where a lot of applicaitons you DO want to run are PC only. As a tangent, I’m not much of a gamer but always bought and enjoyed the Diablo series of games since I loved the first as a kid, but right now the 4th installment is PC or console only, and I own neither. so…
Also, Macs tend to be more expensive than a comparable PC. They have a longer useful life, so amortized over the time you’re using it it’s probably a wash, but… that’s an up-front factor.
I think in practice either a windows or a Mac machine is more than capable of handling a busy mix with a lot of high fidelity audio content these days - video production is the new frontier and that’s way more of a resource strain than anything we’re likely to do. So, the big ones I think I’d point to are extremely reliable, long useful life, and a closed ecosystem that makes hardware compatibility a non-event. Windows has probably closed the gap a lot, but I guess not for nothing while I’m still recording on my first-ever Mac, when I bought a new computer in 2020 for WFH use right as the world was shutting down, it didn’t even cross my mind to look at Windows laptops, I went straight to mac.
