Mailspring

Where Mailspring keeps its logs

Mailspring logs to ~/Library/Logs/Mailspring/ on macOS.

Paths are printed exactly as Mailspring 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.
