When I open the app  a Python error comes out with this description.
Couldn't load plugin "newlayer" from

 If I click OK the application freezes
So I deleted in Application /contents the PyQt4 folder content and then it says : "Impossibile caricare PyQt4. Il supporto Python verrĂ  disabilitato." but opens and works fine with other plugins.

What is wrong with PyQt4?


I don't think anything is wrong with PyQt4. Instead of deleting necessary items from the application bundle, you need to delete your incompatible plugin. From the terminal do:

rm -r /Users/bernardo/.qgis/python/plugins/newlayer

That will take care of the offending plugin. You may have others, in which case, doing:

rm -r /Users/bernardo/.qgis/python/plugins

is probably preferable (start with a clean slate for the new API in 1.0.0).

You also need to reinstall your qgis application because you need everything inside the application bundle. Deleting things from there will break it every time.

Regards,
John
