[Qgis-developer] QGIS 2.18 on OSX

[Paolo Cavallini]

Hi all,
I'm quickly testing QGIS 2.18 on OSX, and I'm finding several annoyances:
* the user is presented a notice about a new version being available
(2.18.4), but when visiting the download page only 2.18.2 is available
* Processing throws an error:
===
Couldn't load plugin processing due to an error when calling its
classFactory() method

TypeError: coercing to Unicode: need string or buffer, NoneType found
