Building a standalone application is largely the same as building a collective. You'll use the collective editor window to script the inclusion of files needed by the standalone. At the very last step, when saving, you choose Application as the type of file you want to create instead of Collective.
A collective file is built as part of the standalone process. The exact details of this process and the format of standalone applications differs between the Mac and Windows platforms. Note that even though your original patcher file might be platform-independent, standalone applications created with Max are definitely platform-specific.
