Yeah, I still don't have a Mac with M1 silicon, so no, haven't even tried... my understanding is that the x86 version works just fine, though... > Here is a log of my frustrations. > > Before leaving for the summer vacation, I received a new MacMini at the > office featuring the new ARM based Apple hardware that everybody is so > excited about.

But also that is solved. I think.

I'm sure you've found this page https://www.qt.io/blog/qt-on-apple-silicon <https://www.qt.io/blog/qt-on-apple-silicon> and if you wanted to experiment with Qt6 there's more stuff here https://doc.qt.io/qt-6/macos.html <https://doc.qt.io/qt-6/macos.html> I think eventually we will need to port to Qt 6 - and that should fix the core of your problem, right? > So I see three options to move forward: „Cross-build“ Subsurface for the old > hardware platform.

Allegedly one can build "fairly decent" Qt 5.15 binaries for M1. Just takes a while :) But really, the only logical path is Qt6 /D
