TIDEScripter is great and i am develping my own IDE programming. What are the limitations for the use with Mac OS X? Are you planning to migrate or supply it for Mac OS? Not all features are needed but general IDE features would be great to create Windows-MacOs Application.
the runtime engine, i.e., scripter execution, works fine on Mac OS X. Also, non-visual debugging features also works. There is a demo in TIDEScripter using Firemonkey that can be executed on Mac OS X. Also, syntax highlight memo is available for Mac OS X, but sold separately. Unfortunately, there is no form designer or object inspector available for Mac.
