Steam

Where Steam keeps its logs

Steam logs to C:\Program Files (x86)\Steam\logs\ on Windows.

Steam logs to ~/Library/Application Support/Steam/logs/ on macOS.

Steam logs to ~/.local/share/Steam/logs/ on Linux.

Paths are printed exactly as Steam 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.
