Hi,
executables compiled by Jabaco can only be used under Windows.
You can, however, instruct Jabaco to create a jar file rather than an exe file.
Just opt for "Jar-File" as file type in menu File/Make.
Unless your program calls Window specific controls or features, the jar files should be executable on a Mac.
Make sure, a Java runtime environment is available.
Please let us know your findings.
Happy experimenting!
