[GRASS-user] error message from GRASS 7 on mac os

[William Kyngesburye]

You don't, the developers fix it in the code (as Anna did) and it will be in the next release.  But, the CGContext errors should be harmless, and you can ignore them.

If you installed PIL, I don't know why cartographic composer preview is not working. Maybe you have installed other versions of Python (besides the system python) and GRASS is not using the right one?

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly what the universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarrely inexplicable.  There is another theory which states that this has already happened.
