I actually own Quadrium Flame and Quadrium 2 --- excellent. I am now also looking  Mandelbulb 3D.  I have version 1.7.5.1  It downloaded with Wine (for the Mac)  I see from posts elsewhere that the most recent version of Mandelbulb is 1.7.9.3 ... 

However that appears to be for Windows only.  Is that version available somewhere for the Mac?

Lenord - you're a wonderful help. I have just signed onto the Fractal forum and am waiting for the moderators to authorize me.

Thank-you.
