It should work on Mac OS as well. I have a colleague working on mac without problem.
I understand the error that you get but it shouldn’t happen, this is really puzzling.
Can we continue this disscussion by email ? (email@example.com).
I will need a sample of your images to try to reproduce your bug and eventually use some screen sharing service to show me how this bug occurs.
Since this software is really on the first version I expect to have some bugs to fix but I need to be able to duplicate the problem to fix it.
