Creating `.app`s on the Mac with Lazarus 3.4 [SOLVED]

[carl_caulkett]

What is the latest on how to create a self-contained `.app` package using Lazarus. I'm using Lazarus for the first time in over a year, and I've just tried building a simple form, as by default, it still just produces the raw `Unix Executable`.

Is there a simple, one or two step way of producing a self-contained `.app` package that behaves just like any other Mac application?

Menu Project, Project Options. On the bottom of Application (Application settings) there is 'Create Application Bundle'.

Thanks! I did try to search for that menu option before but couldn't find it! I notice that it creates an alias to the `Unix Executable` rather than doing a full copy. I did, in the meantime, get some advice from a friendly chap called Claude Sonnet 3.5 who gave me a shell script which does much the same thing...
