I'm running the latest QGIS3.0.3 under Mac OS X 10.12.6.
It was freshly installed using "QGIS-macOS-3.0.3-1.dmg" from qgis.org
Right after starting QGIS3 I find the following Processing messages in
the Log Messages panel:
2018-05-28T16:37:35 CRITICAL Could not open SAGA algorithm:

I checked the file mentioned in the first (CRITICAL) message:
~/QGIS/python/plugins/processing/algs/saga/description/RiverGridGeneration.txt
It does indeed contain 0xc3 at byte 75 - as the Unicode lead-in for an
'a' with umlaut (diaeresis) mark. There are also 2 other cases later
in the file for 'u' with umlaut.
However, when I edited the file to replace the ä and ü with plain ASCII,
this had no effect on the next QGIS3 startup - same error. Perhaps the
"RiverGridGeneration.txt" data is cached somewhere?
So, my 2 questions are:
1) how to fix the CRITICAL error
2) what are the implications, if any, of the WARNING messages
I hope someone can help. Many thanks,
