**Note:** Before bug reporting, please make sure you have tried the **latest** (alpha) version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS Console.app's "Crash Reports" section. * * * **Describe the bug** If you set both "Start clean mode automatically when launching KeyboardCleanTool" and "Reopen windows when logging back in" to on, then shut down or reboot with KeyboardCleanTool running. It may occasionally cause macOS login to fail even if you enter the correct password. The weird thing is, you can still see dots in the password box after you press the keyboard. But macOS still tells you your password is incorrect. ## Note: The app doesn't enter cleaning mode while shut down or rebooting. **Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):** * * * **Screenshots** If applicable, add screenshots to help explain your problem. (You can just paste or drag them here) * * * **Device information:** - Type of Mac: MacBook Pro M5 pro - macOS version: Both 26 and 27 - KeyboardCleanTool version: Version 8.3 (12) * * * **Additional information (e.g. crash logs, related issues, etc.):**
