I have dowloaded the RapidWeaver update from 8.1 to 8.1.1 three times. Each time the program exits when I press load and re-open. I am using OS X El Capitan on an iMac 8.1. This computer won’t update beyond El Capitan. Is the RapidWeaver update only compatible with newer OS X versions?
Updates for any app can break. Download the full RW from RM’s site and install it.
