Just to be sure: is it ok to have TF 5 times in my Login items (see screenshot)? Or should I remove 4 of them and then, which ones?
You can safely remove any four of them.
I’m wondering why those items duplicate for some people.
I’m using this bash script as a post-install step, it first tries to remove existing TotalFinder items and then add a new one at the end of the list:
# add /Applications/TotalFinder.app in user's login items
LOGIN_ITEM_PROPERTIES="{ name:\"TotalFinder\", path:\"$TOTALFINDER_APP_DIR\", kind:\"application\", hidden:false }"
/usr/bin/osascript -e 'tell application "System Events" to delete login item "TotalFinder"'
/usr/bin/osascript -e "tell application \"System Events\"" \
-e "make login item at end with properties $LOGIN_ITEM_PROPERTIES" \
-e "end tell"
