One of the hits I got was https://www.networkworld.com/article/665211/byod-mac-users-p... — so Linux users obviously pay even more when they are interested ;)

My point being that this is a bit niche, and overall trends might not apply.

Are Mac users more likely to pay? Likely yes.

Are the total number of Mac users who pay higher than the total number of Windows users who pay? I kind of doubt it. Windows market share is still much higher than MacOS.
