Personal notes and verified solutions for technical issues, login errors, and configuration limits I encountered while running Path of Exile on macOS.
Symptoms
When attempting to log in, the client displays an error message and prevents connection, even after restarting the game or the system.
Cause
The locally cached login credentials file (production_login.credentials) remains out of sync with the latest server patch version, causing the server to recognize the client as outdated.
Solution
Cmd (⌘) + Shift + G.~/Library/Application Support/Path of Exile/Cache
production_login.credentials.Symptoms
The in-game UI menu restricts the selectable resolution options, preventing users from lowering the resolution further to improve performance or frame rates on macOS.
Cause
The graphical interface enforces preset minimum resolution bounds based on the active display scaling, locking lower custom resolutions in the drop-down menu.
Solution
You can manually override the resolution parameters by editing the configuration file.
Cmd (⌘) + Shift + G.~/Library/Application Support/Path of Exile/Preferences
production_Config.ini using a standard text editor (e.g., TextEdit).resolution_width=1920
resolution_height=1080
1280 and 720).
