Hi Etsuko Inside QGIS 3.30.x for macOS there are still the old libraries of SAGA version 7.8 and so the SAGA Next Gen plugin works without providing any paths. I use this system. If, on the other hand, you want something more such as using SAGA 9, the latest version, where there are many new algorithms, you need to download SAGA for Mac, currently 9.0.2, directly from the SAGA website: https://sourceforge.net/projects/saga-gis/files/SAGA%20-%209/SAGA%20-%209.0.2/ It is a normal application that you drag into Applications. Then in QGIS inside Processing > Providers > SAGANG > SAGA folder enter the path: /Applications/SAGA.app/Contents/MacOS
Press OK and you have all the algorithms in the latest version of SAGA 9: QGIS works fine. For those who have the Apple Silicon processor, however, better install QGIS3, currently 3.28.7, from MacPorts. QGIS3 is native with all the native external libraries (including SAGA, GDAL, Grass, etc.) and the performance is spectacular.

I installed the SAGA Next Gen plugin, and it says it requires a manual installation of SAGA 7.2 binaries. I see a folder for SAGA 7.2.0 under SAGA GIS on Source Forge, but there are no binary files for Mac for this version. I ran Topographi Analysis despite the lacking file, it seemed to have run fine but was not able to save the resulting output. I contacted the SAGA help and was instructed to follow the installation instructions here https://sourceforge.net/p/saga-gis/wiki/Compiling%20SAGA%20on%20Mac%20OS%20X/ However, the program failed to compile at the very last step and generated this error. CMake Error at /usr/local/Cellar/cmake/3.26.4/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES) If anyone knows how to use SAGA Next Gen on MacOS (I have macOS Monterey version 12.6.6), I would appreciate any help. Thank you very much.
