I would like to update QGIS from 2.2 to 2.4 on Mac OS X (10.8) but I cannot find how to do so.

Do I have to uninstall and re-install all from KyngChaos? If so, I would therefore lose the extensions I have added manually.

Nothing is really clear about this on the Net.


No problem, you only need to download QGIS 2.4 and install it.

  1. the application (QGIS.app) is placed in /Applications/
  2. the frameworks are in /Library/Frameworks/ (/Library/Frameworks/GDAL.framework for example)
  3. the extensions are in /Users/you/.qgis2/python/plugins (hidden folder, /Users/me/.qgis2/python/plugins/tablemanager for example)
  4. the Python modules are in /Library/Python/2.7/site-packages (/Library/Python/2.7/site-packages/matplotlib for example)

You can upgrade 1) or 2) or 3) or 4) independently. (Mac Os X is an UNIX system)

If you want to keep the old 2.2 version, rename the application, QGIS_2.2.app, for example, otherwise QGIS.app is replaced by the new version.
