Hello!
Using Cura on my Windows notebook, I saved a .3mf file with all information such as printer profile and print settings. I tried to open it in my Macbook and it didn't import project info, just the 3D model. To test if the problem was my Mac or the file itself, I reinstalled Cura on Windows, without any previous settings and opened this .3mf file. All project settings were loaded properly along with the 3d file.
Then, using Cura on my Mac I saved another .3mf project and opened it on my Windows and it also worked fine.
I use Cura version 4.6.`1 in both computers.
Why isn't my Mac opening .3mf files properly?
