@Martin4844 this looks like the most recent thread on the topic:
Q) How soon will the Mac version be coming out?
A) Not very soon I must admit. I am sorry I can’t keep my promises
from last year. I was very confident I would be able to release in
winter last year but it turned out to be impossible for various
reasons. First of all releasing on macOS forces me to rewrite a large
part of the original source. And it’s not just simply a rewrite, I
want to improve the source code to be able to add new features much
more quickly than with the 1.x. Secondly, some people may know this,
Qubicle is not my main work. I am a freelance ui designer and Qubicle
is my side project. Last year was a very successfull year for me. I
had a lot of jobs and therefore little time for Qubicle. I made a lot
of money but I can’t say that those projects were in any way as much
fun as coding Qubicle is. So I made the decision to turn my perfect
plan b - which is Qubicle - into my plan a, meaning I will work
full-time on Qubicle starting from march. So when will Qubicle 2.0
come out? That’s still hard to tell. I think I can give a proper
answer when I am two month in. Definitely this year but not before
june, rather later. Ask me again in april.
