I have installed the new version of QGIS (2.12) and the newest OSX version (El Capitan). When I tried to open GeoTif files with QGIS, it always crashed! Then I tried an older version of QGIS (2.8) and the same problem appeared! I don´t know what to do know and I hope there is anybody who is good with QGIS and MAC!
I was having the same issue with the package installed following the Kyngchaos website. I installed GIS 2.8 via Homebrew following this tutorial and now I'm able to import GeoTiff files.
Summary of the installation process:
brew install postgresql brew install python export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH pip install numpy scipy matplotlib processing psycopg2 brew install gdal brew tap osgeo/osgeo4mac brew install qgis-28 brew linkapps qgis-28
