OS X El Capitan introduced a new security feature called "System Integrity Protection". It needs to be disabled to let Refog record passwords on your Mac. This measure is a compromise, but it should not make your system any less secure than previous versions of OS X without the feature.
To change system configuration please follow these instructions:
- Restart your Mac and hold down the Command and R keys at startup.
- Hold these keys until the Apple logo appears. After your computer finishes starting up, you should see a desktop with an OS X menu bar and an OS X Utilities window.
- Use Utilities > Terminal menu
- Type the following text in Terminal window and press Enter:
Refog should start recording passwords after you restart the computer.
How to Restore Original Configuration
You can re-enable "System Integrity Protection" any time by repeating the instructions, but using this command in the Terminal instead:
Refog will no longer be able to records passwords, but all other features will keep working.
