Thanks for your report. Can you please attach a crash report (Applications > Utilities > Console > Crash Reports)?
We know there are some issued with QCAD on M1 due to the Qt version being used. We are working on an update to Qt 6 but that is a major effort that will still take some months.
I also have this problem. It’s a waste of money for apple. Hopefully someone will address this soon. It’s the only product that pretends like it should work.
If you experience crashes on M1, please open your download link and download the package:
“QCAD Professional 3.28.1 (f) for macOS Qt 6 11.x, 12.x, 13.x arm64 (M1/M2, NOT for regular Intel Macs!)”
Note the “Qt 6” part in the package name.
This package uses a newer Qt version (Qt 6) which should hopefully fix these issue. Please report back if you experience any problems with this package.
Unfortunately, we haven’t been able to reproduce these crashes here, so they don’t seem to be occurring on all M1 systems or might depend on system preferences or other individual settings.
