+ARM-64 builds are not currently supported on MacOS as of **26-03-24.**
+However, building Polykey yourself on MacOS resolves in a working binary. Follow this guide below to manually build and install Polykey on macOS.

-Builds for MacOS are released on GitHub: https://github.com/MatrixAI/Polykey-CLI/releases.
+### Manually
+
+1. Download the Polykey CLI for macOS from the [GitHub releases page](https://github.com/MatrixAI/Polykey-CLI/releases). Look for the file named `polykey-cli-V.V.V-darwin-universal`, where `V.V.V` is the version number. For Mac, you want to download the file with the `darwin-universal` file extension.
+
+2. Rename the downloaded file to `polykey` for easier access. In your terminal, make sure to navigate to the directory where the file is located (usually the Downloads directory) and run the following command:
 
-Download the executable named `...-polykey-cli-V.V.V-darwin-universal`, and rename it to `polykey`.
+```sh
+ mv polykey-cli-V.V.V-darwin-universal polykey
+```
 
 :::tip
 
-Make sure to cd into the directory where your Polykey CLI executable is located first. Typically this would be your Downloads directory.
+- Replace `V.V.V.` with the actual version number of the file you downloaded.
+- Navigate into the directory where the file is saved to execute commands.

 Before you can run the Polykey CLI, you need to make it executable. Use the chmod command to add executable permissions to the file. Replace polykey-cli-0.2.6-darwin-universal with the actual name of the file if it's different:
 
 ```sh
-chmod +x polykey-cli-V.V.V-darwin-universal
+chmod +x polykey
 ```
