-#### **4. Install Required Ruby Version (recommended)**
+#### **4. Increase File Limit (Important for MacOS)**
+
+To avoid errors when running tests on MacOS, you might need to increase the number of files your system can open at once. Here's how:
+
+1. Run the command:
+```bash
+ulimit -n 1024
+```
+2. To make the change permanent, add the above line to either `~/.zshrc` or `~/.bash_profile`, depending on your shell.
+
+**Note:** MacOS has a low default limit of just 256 open files. If you exceed this while testing, you'll see an error like: `Too many open files - getcwd (Errno::EMFILE)`. This step helps prevent that.
+
+#### **5. Install Required Ruby Version (recommended)**

 Navigate to the git checkout of the OpenStreetMap chef repo and run:
 ```bash
 rbenv install
 ```
 This will install the recommended version of ruby for running the tests. The recommended version of ruby is defined in the [.ruby-version](.ruby-version) file.
