Is supporting macOS worth it for indie software development?

Hi!

I have heard many times that supporting Linux can be financially unreasonable for some companies and developers because of its low market share and disproportional technical issues. And if you need to rewrite 30% of your code to support a new operating system/platform but it will add less than 5% to your sales in the most ideal situation, it would indeed make very little sense to do so.

But what about macOS?

I'm currently making a tool for digital artists, and I know some of them might be using macOS. But, if market share statistics are to be believed – and assuming macOS isn't specifically preferred by digital artists – then one would expect less than 15% of clients to be on macOS.

Although I'm using frameworks that work on all the three OSes, a considerable chunk of my code is OS specific. So I'm considering only supporting Windows initially. And only adding support for other OSes when there is sufficient demand.

What do you think about this line of reasoning? And thank you for reading my post!
