I know it’s installed correctly since G1 can use Robofab for word-o-mat. I get this error in the macro panel when i start up:
Is G2 using a newer version of Python? Robofab and Vanilla is in '/Library/Python/2.6/site-packages' at the moment
Yes. Glyphs 2 is using python 2.7. You can just copy the content of the 2.6 site package folder into the 2.7 folder.
