Have iMac with OS 10.7.5. This is the first time I am installing QGIS. Everything was downloaded from kyngchaos.
This is what I did in that order: Downloaded QGIS-2.12.0-1. Tried to install. It asked for GDAL 1.11. Got GDAL_complete 1.11(EB). Installed. Next QGIS asked for matplotlib. Got matplotlib-1.4.3. Installed. Next QGIS asked for PROJ_framework 4.9. Got PROJ_Framework-4.9.2-2. Installed. Next QGIS asked for SQLite3_Framework. Downloaded SQLite3_Framework-18.104.22.168-1. Installed. At this point QGIS installed.
When I click on Q in applications, it says 'QGIS quit unexpectedly'. ERROR:EXC_BAD_ACCESS (SIGSEGV)
Clearly something is not as it should be. What do I need to do?
