GH for mac bugs

I think there are some bugs in GH for mac. 

1. I wanted to make a even/uneven selection of a tree with this line {(0,2,...);(0,2,...)}
But it returns Char '...' is not a recognized rule notation symbol.

2. The text tag 3D does not really work in most cases, also the sizing does not work.

Is this possible? are there any workarounds for now?

Best regards,

Vincent
