[Bernhard Stegmaier <stegmaier@xxxxxxxxxxxxx>]

If I remember correctly I checked these bug reports also when I started with KiCad on OS X.
The mentioned changes seem to be in wxWidgets. 
But, only in the carbon folder and I don’t know if any of those sources are relevant for the cocoa build.
I guess so, because those source files also contain #ifdef’s about cocoa and there is nothing similar in the other folders.

Hoping for the best, back then I disabled all the overlay stuff in KiCad, removed all the patches from wxWidgets and tested that.
This did everything but work… you can make nice abstract paintings with your mouse on the canvas, though… :)
Maybe I just did something wrong, so if anybody else is willing to try...


Regards,
Bernhard
