I suspect that the compatibility warning is caused by having set the
'Open in 32-bit mode' checkbox in Finder Get Info on the LiveCode app
in 10.13 and before - an upgraded OS remembers the setting but it isn't
user-visible anymore :|

The Finder setting for which apps launch in 32-bit mode by default is 
in:

    
~/Library/Preferences/com.apple.LaunchServices/com.apple.LaunchServices.plist

 From terminal (assuming you have Xcode installed) you can do:

   open 
~/Library/Preferences/com.apple.LaunchServices/com.apple.LaunchServices.plist

Then if you remove the key:

   RootLSArchitecturesForX86_64v2/com.runrev.livecode

Save, then relaunch Finder and then relaunch LC you *should* find LC 
runs without
the warning (as it will be running in 64-bit mode).

Warmest Regards,

Mark.

P.S. If anyone knows where a UI for the above option exists in Mojave 
then please
let us know, the above was the only method we found late last year when 
we had
someone ask in Support about it.
