I have 2 questions... please don’t be biased for the first one as I know you guys dislike macs

So I have a friend that wants a laptop for audio editing, and he’s more familiar with Mac. Should he get a mac or is a windows laptop better for audio editing etc? Also, does the graphics card really matter if all he wants is audio editing? Should I look for a build with a good cpu and only a decent gpu? If you want to suggest a laptop directly, he would like one under 500 dollars. Thanks! Have a glorious day!
