After a little more tinkering I've found the problem. Simply deleting the preferences plist file (which appears to be $HOME/Library/Preferences/org.qelectrotech.QElectroTech.plist) was not sufficient because MacOS Big Sur appears to cache the information. To fully get back to the original configuration, I did the following:

rm -rf ~/.qet; find ~/Library -iname \*qelectro\* -exec rm -rf '{}' ';' 2>/dev/null

and then rebooted. Seems a little crazy, but now I have the original configuration. Given Laurent's response I would imagine that simply deleting the plist file and then rebooting would have been sufficient.

Here are the files I see after I opened QElectroTech once:

fahnoe@luna ~ % ls -la ~/.qet; find ~/Library -iname \*qelectro\* 2>/dev/null

Pour Mac OS X :
$HOME/Library/Preferences/QElectroTech/QElectroTech.plist

Thanks Laurent, however I do not have that file:

fahnoe@luna ~ % ls -l $HOME/Library/Preferences/QElectroTech/QElectroTech.plist
ls: /Users/fahnoe/Library/Preferences/QElectroTech/QElectroTech.plist: No such file or directory
fahnoe@luna ~ % find . -iname QElectroTech.plist 2>/dev/null                   
fahnoe@luna ~ % 

Here is the most recent log if that is of any help

I'm new to QElectroTech having just started using v0.8 on a Mac. After some initial efforts I am also seeking to reset all of the configurations back to their defaults. I have removed the following files/directories, as well as removing and reinstalling the app, however I'm not able to get the default configuration back.

~/.qet
~/Library/Application Support/stalefiles/QElectroTech
~/Library/Saved Application State/org.qelectrotech.savedState
~/Library/Preferences/org.qelectrotech.plist
~/Library/Preferences/org.qelectrotech.QElectroTech.plist

I've also looked at the MacOS defaults and don't seem to find the configuration there. Where else is the configuration stored? Thanks.
