To compile stuff for macs without having to buy a mac

I don't understand why you would want a hackintosh or a mackintosh for that matter. There's linux and openbsd. Sooo what's the advantage? Apple looking ui?

Commercial software on Unix system is appeal for many tech types that would dabble in hackintoshing. If you own some other Apple devices then integration becomes a big factor too. For me personally it's a taste of computing from the old days, I grew up in a world of C64s, Amigas, IBM compatibles. I used everything from FreeBSD, BeOS to hackintoshed MacOS and OpenIndiana as daily drivers. These days I use an M1 Air with MacOS since don't have that much free time.

Not being able to split screen without paying?

A great many people really like OSX; its been a long time since i've daily driven it but there's stuff about the way it works that feels more efficient than windows, and easier than linux. That's not something that appeals to everyone but its obviously worked for a lot of folks.

So back in the day it was about getting to use OSX (and in other cases apps that were OSX only, or just ran better in OSX) but not having to pay so much for the hardware. That's a calculation that to me really only made sense for desktops; as for quite a long time Apple's laptops weren't actually massively more expensive than a similarly spec'd windows laptop.*

Overtime i'd argue that linux desktops have caught up to a lot of what made OSX feel good; but they're not like for like even now. Though take that with a grain of salt as I spend more time in cli/tui nowadays across my macbook, work windows laptop and various linux boxes i've got running :)

*The thing was that the average windows laptop was under-spec compared to a Macbook Pro so the latter always looked way more pricey.

It usually just works. I’d rather not have to spend hours in config files to get my linux system setup the way I want. I run linux in a vm. But I say this for a legit mac. If I was going to go to the trouble of running a hackintosh, I probably would just go to linux at that point. But there is the case of mac software too if there is something there that is a must have
