Tunnelblick

Where Tunnelblick keeps its logs

Tunnelblick logs to /Library/Application Support/Tunnelblick/Logs/ on macOS.

Paths are printed exactly as Tunnelblick writes them. Environment variables like %LOCALAPPDATA% and $XDG_STATE_HOME are never expanded, so a path can be pasted straight into a shell. Where a path differs between installer types or shipping flavours, each one is racked as its own card below - why that happens.
