Like what? Obviously there's Logic Pro and MainStage - but it isn't 1999 where you're buying a mac because they come with firewire. Plugins that exclusively ship as AU are very rare. Every big-name DAW supports Windows.
Off the top of my head, reasons to use MacOS over Windows are mostly about convenience. The Audio/MIDI Setup tool is fantastic for routing and aggregating devices. You can sidestep the whole shit-show that is ASIO, which, while better these days, remains a niggle. As someone else said, Macs support high-impedance headphones. The built-in speakers are better than anything I've heard in another laptop brand. It's also helpful that when you do have an issue, the forum threads you'll find will likely be relevant; rather than wading through forum threads started by Jimmy who is having similar-sounding but unrelated issues stemming from his Acer shitbook's preinstalled EZHiDefAudio® driver conflicting with ASIO4ALL.
Conversely, only having USB-C is a pain unless you're only going to connect devices made in the last few years. Or carry dongles. Upgrading the 512GB SSD to 2TB (so you can actually store all the plugins and sounds Logic Pro ships with) will cost you an obscene $600. Not all DAWs treat MacOS as a first-class citizen - Yamaha still ship shit that depends on Rosetta, Cubase only works via CoreAudio2ASIO, and some of their drivers require rebooting to bypass SIP on installation. And it doesn't help Apple clearly care less than they used to about polishing their OS updates.
Honestly, the main questions to ask yourself are "how much can you afford", "what software are you going to use", "what devices are you going to connect", and "are you going to do anything else".
