Problem with FreePascal + MacOS

Yes, but do you use TThread?

For sound streaming I use BeginThread. And I add unit cthreads to my uses clause.

APPTYPE seems to don't work in MacOS?

If you were read FPC documentation, you would know this...

Also, I can't really get a single window application running, APPTYPE seems to don't work in MacOS?

GUI applications under MacOS X are not an one single executable. You must "build" your own Bundle. Simple description "what is Bundle" can sounds like this: "Bundle is a directory with name which contains part "name" and ".app"(for example - MyApp.app). Inside this directory must be another one - Contents. Inside Contest must be directories Frameworks(for your libs/etc.), MacOS(for your executable, which must be with the same name as your bundle, in our case - MyApp) and Resources(where you must put all your resources)".
