CCL 1.11.8 (for Mac App Store users)
This release is for people who had been using the Mac App Store version of CCL, which no longer works on pre-Catalina systems.
Download the ccl-mac-ide-1.11.8.zip
file, double-click it to uncompress, and then move it to the /Applications
folder. It has a different bundle ID than the app store version, but it should otherwise be the same.
