About

This guide is a list of things to try for fixing non-working input for Etterna 71-72.x on macOS. (not Etterna 70.x) It should be used to debug when neither the mouse nor keyboard work on the main menu, but the game otherwise seems to start correctly without any errors. If one of the mouse or keyboard works, but not the other, this guide almost certainly won't help. Similarly, if the game doesn't reach the main menu for whatever reason, this guide won't help either.

Things to Check Before Other Steps

• Make sure Etterna has been copied out of the installer dmg, and that the version attempting to run is being launched from the copied-to location, and not from inside the dmg.
• Make sure that the com.apple.quarantine xattr flag is not present on any of Etterna.app, Etterna.app/Contents/MacOS/Etterna, or crashpad_handler. Etterna 71.x should automatically remove the xattr flag from Etterna.app and Etterna.app/Contents/MacOS/Etterna, but might not from crashpad_handler.
