Not in this regard. I don't think there was any point at which iMessage on Hackintosh was impossible without a donor, but I've personally been using it since ~2015.

Maybe you got lucky with your hardware? I can’t remember all the exact details but these posts are all from the same 2017-2018 window and the solutions all resolve around network hardware: https://www.google.com/search?client=safari&sa=N&hl=en-us&q=...

It’s been too long for me to remember more than this, but I did have iMessage on a hackintosh circa 2013 or so but wasn’t able to get that to happen when I tried in 2017/2018.

It's not luck! :) https://www.insanelymac.com/forum/topic/303073-pattern-of-ml...

Notably, you need to get this right on the first try (or at minimum the first try), or Apple appears to get suspicious for requests from your IP.
