KeyShot 5 don`t open .bip files on my Mac

[Eldar]

I just installed the new Keyshot version, but it doesn't work, can`t open .bip files made in version 4 or import new geometry. The scream turns weird and the program frises. I never have this problem with the version 4. I have the educational license. Attach a picture with the problem and my iMac configuration. I delete the version 4 and reinstall the version 5 but not resolve the problem ¿Any suggestions?

Can you try to drag an drop?

Thanks Thomas, sorry for the late answer. Drag an drop solve the problem for open and import files. But when I work and change the materials parameters like colors, peculiarity, change the procedural parameters, move the camera, etc.  Soon or late the viewport fries. All the buttons still work but don't update the viewport and I can't orbit the model. It only happend whit the new version. ¿Anyone have this issue?
