[Qgis-user] Error installing QGIS 2.8.2-1 on Mac

[Jesús]

Trying to install 2.8.2-1 on a Mac (10.9.5) I find this error:

Dyld Error Message:
  Library not loaded: /Library/Frameworks/PROJ.framework/Versions/4/PROJ
  Referenced from: /Applications/QGIS.app/Contents/MacOS/QGIS
  Reason: Incompatible library version: QGIS requires version 10.0.0 or
later, but PROJ provides version 8.0.0

I delete old version first but I can't open new version when finishing the
installation. I got this message: Qgis can't be open due to a problem.

Any idea? Thanks
