+Troubleshooting
+---------------
+
+* If you are running on Mac OS and getting compilation errors when calling DaCe programs, make sure you have OpenMP installed and configured with Apple Clang. Otherwise, you can use GCC to compile the code by following these steps:
+    * Run `brew install gcc`
+	* Set your `~/.dace.conf` compiler configuration to use the installed GCC. For example, if you installed version 9 (`brew install gcc@9`), run `which g++-9` and set the config entry called `compiler.cpu.executable` (empty string by default) to the resulting path
+	* Remove any `.dacecache` folders to clear the cache

 Configuration
 -------------
 
 DaCe creates a file called `.dace.conf` in the user's home directory. It provides useful settings that can be modified either directly in the file (YAML), within DIODE, or overriden on a case-by-case basis using environment variables that begin with `DACE_` and specify the setting (where categories are separated by underscores). The full configuration schema is located [here](dace/config_schema.yml).
 
 Useful environment variable configurations include:
 
-* `DACE_CONFIG` (default: `~/.dace.conf`): Override DaCe configuration file choice.
+ * `DACE_CONFIG` (default: `~/.dace.conf`): Override DaCe configuration file choice.
 
 General configuration:
  * `DACE_debugprint` (default: False): Print debugging information.
