Doesn’t really seem to work because if I start:
STTRACE=model /Applications/syncthing 2>&1 | tee /Applications/syncthing.log
as advised here: Keeping Syncthing Running: Mac OS X (LaunchDaemon)
syncthign starts without its configurations its basically empty, doesn’t know about any repositories or nodes so I cannot test the “Override Changes” link or are you still interested in the log file as is? If you would like to see the log file, can I post it here or is there anything sensitive in there?
