Gear wise I'd stick to Mac just bc most music gear only works with windows or Mac. And for a daw even GarageBand will work perfectly fine depending on your needs.

Considering everyone and their great great grandma from the horse n buggy era suggests a Mac, I guess I'll just be stupid and get a Hewlett-Packard PC with Windows 98 on it. My music will sound like it belongs on an 8 bit Nintendo system, but oh well. 🙃
