If you are running on a low specification Mac and/or you have a lot of other projects open while running LCFM Native, you may see errors like this:
Assuming you have checked your keyboard settings, and you weren't doing anything else on the computer at the time, the problem may be a lack of processing power. You can try quitting everything except LCFM Native, but if this still isn't enough, you can also reset the timeout interval in the LCFM Native preferences.
Go to the LCFM Native menubar item, and select Preferences.
Drag the slider to a suitable number. As mentioned in the description, the higher number you set it to, the longer your extract phase will take.
