If you run the Mac version of Easy Data Transform from the command line in macOS 14 you may get a message:
WARNING: Secure coding is not enabled for restorable state! Enable secure coding by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState: and returning YES.
This warning is due to a change Apple made in a library. We were looking at ways to get rid of it, however we have been informed that the issue has now been fixed by Apple in macOS 15. Thanks to Jesse S. for reporting this.
