The problem is probably that 3rd-party catboost library that is included in the dmg is compiled for a newer CPU architecture.

Can you try running

/Applications/Orange3.app/Contents/MacOS/pip uninstall catboost

in the Terminal and run again.

Hi ALes, Thanks a lot. It does start now.

Thanks, @ales-erjavec, good find!

@VesnaT, catboost is an optional dependency, right? So apart from checking if catboot is installed, we should probably catch another exception that happens here. @ales-erjavec, do you remember which exception gets raised and when? At import?

[ales-erjavec]

There is no exception to catch. The process aborts with a SIGILL signal at import.

We discussed this at today's meeting. There's not much we can do about it, except for printing a warning to uninstall catboost if we detect the CPU architecture is too old.
