Thank you for your posts, we are looking in to the material editor issues. We are also preparing some updated documentation that runs through the Mac Material Editor as there are some particular combinations of selections that will help you get the most out of the Mac material editor.
Samyell - Please could you repost the video, or send it directly to support@artvps.com as the attachment to the post is less than 1Kb.
Also Batch rendering is something that is in our development plan, so hopefully this is something that we will have in a future release.
[With regards to the zooming and panning, this has been answered on our forum. So hopefully using the 'CMD ⌘' key with the wheel is working ok for you.]
The default control for zooming the Mac screen is setup to be 'Ctrl' and the wheel. So if your mac has been changed to 'CMD' and the wheel then this will get priority and Shaderlight will not be able to zoom in the render window. Panning the image should just be the left mouse button.
I hope this helps, thanks for the feedback.
