I couldn't find anywhere what the name and location of the RumLogNG log file is when using iCloud Synced Logbook
I need to enter it into GridTracker 2 or JT Bridge
Thanks for the answer.

There is no file you can use. The iCloud synced logbook is controlled by macOS.

try
To save logbook elsewhere then we need : logbook / iCloud sync logbook / export .
