If you want your compilation to be compatible with older system, use the -mmacosx-version-min flag (for example -mmacosx-version-min=10.5). To force compilation in 32 bits use -arch i386. You can do that by setting environment variables before compiling all the libraries and ScummVM:

If you plan to build the ScummVM app bundle, you will need to generate static libraries. For most of the libraries this is done by default, but for a few you need to specify you want static libraries when invoking configure. Here are suggested configure options for each library. If the library is not listed in the table below this means the default is fine.

== Compiling ScummVM via the XCode GUI ==
Also if you run scummvm from the command line, you will need to set the Theme path in the ScummVM options so that it finds the modern theme. The themes are in gui/themes/ in the source code repository.


=== Creating an XCode project ===
== Compiling ScummVM via the Xcode GUI ==
 
=== Creating an Xcode project ===
* Compile '''create_project''' inside devtools/create_project
* Compile '''create_project''' inside devtools/create_project
* Copy the generated create_project tool in the ScummVM root folder
<syntaxhighlight lang="bash">
* Run the following:
make devtools/create_project
<source lang="bash">
</syntaxhighlight>
./create_project . --xcode --build-events --disable-nasm
Or alternatively you can use the Xcode project in devtools/create_project/xcode. Open it in Xcode or run the following command:
</source>
<syntaxhighlight lang="bash">
cd devtools/create_project/xcode; xcodebuild
</syntaxhighlight>
* Run create_project '''from the root ScummVM directory''':
<syntaxhighlight lang="bash">
./devtools/create_project/create_project . --xcode
</syntaxhighlight>
 
Note that `create_project` accepts most of the same flags that `configure` accepts.


=== Build the XCode project ===
=== Build the Xcode project ===
* Open and build the XCode project
* Open the Xcode project
* Note that you may need to change the project architecture. Click on the ScummVM project, and change "Architectures" to "64-bit Intel (x86_64)"
* Go to Product -> Scheme and set the scheme to "ScummVM-macOS"  
* If you're using XCode 5 or newer, you will also need to go to Product -> Scheme -> Edit Scheme -> Run tab -> Options tab and uncheck "Allow debugging when using document Versions Browser", otherwise the invalid "nsdocumentrevisionsdebugmode" option will be passed to the ScummVM executable by XCode
* Go to Product -> Scheme -> Edit Scheme -> Run tab -> Options tab and uncheck "Allow debugging when using document Versions Browser"
* Build with Product -> Build or Product -> Run
