[Qgis-user] saga disappears from QGIS 2.18.14 on mac os Sierra

[Olav Peeters]

Thanks Carlos,
this is indeed the same issue. I had the issue on OSX 10.13.2, both with
QGIS 2.18.2 and 2.18.14 (the KyngChaos version with prepackaged SAGA).
After not being able to find a solution I just started using SAGA on a
different machine when needed.

On OSX you apparently need to be root to be able to edit the
SagaAlgorithmProvider.py file
So do e.g. this in a terminal:
sudo vi
/Applications/QGIS.app/Contents/Resources/python/plugins/processing/algs/saga/SagaAlgorithmProvider.py

go to line 76 (:76)
change:
if not version.startswith('2.3.'):

to e.g.:
if not version.startswith('2.2.'):

to check your SAGA version execute:
/Applications/QGIS.app/Contents/MacOS/bin/saga_cmd

Cheers,
Olav
