    5. Install ProFUSE.  It is distributed with Golden Gate.  When you purchase Golden Gate, you should be given access to a GitLab repository.  Among the projects there is ProFUSE which allows your Mac to mount ProDOS volumes.  This is used by the build environment to create the bootable disk images.
    5. Install the [Apple IIgs project template](https://github.com/jeremysrand/Apple2GSBuildPipeline/releases/download/2.0/Apple2GSXcodeTemplate.pkg).  Note that the next time you launch Xcode, you will be asked whether to load the OrcaM.ideplugin.  This is part of the project template and will provide better syntax highlighting for assembly and resource files.  Select the "Load Bundle" option in the dialog that Xcode shows you.
    6. Install and setup the [GSPlus](https://apple2.gs/plus/) emulator or the [GSPort](http://gsport.sourceforge.net) emulator.  Either should work.  No matter which you choose, make sure you put a copy of your Apple //gs' ROM into a file called ~/Library/GSPort/ROM (where ~ represents your user's home directory).  Unfortunately, the Finder by default hides the Library folder from you so the easiest way to accomplish this is probably from the Terminal.
+   7. If you plan to use Merlin32 based projects, install the [Merlin32 binaries and libraries](https://www.brutaldeluxe.fr/products/crossdevtools/merlin/). By default, the build system assumes you have installed the Merlin32 binary in /usr/local/bin and put the library macro files in /usr/local/lib/Merlin. If you installed them somewhere else, you can override these location in your projects.  Note that in the distribution, the macro files in the library had CR/LF line endings and did not work until I converted them to have LF line endings.
