 ### Step 1.5: Apple Silicon users only: install Rosetta
+> To determine if you are using an Apple with Silicon or an Intel-based processor, select the **Apple** menu icon in the top-left of the desktop and click **About This Mac**. On Mac computers with Apple silicon, About This Mac shows an item labeled **Chip**, followed by the name of the chip (ex. **Chip** Apple M1 Pro). On Mac computers with an Intel processor, About This Mac shows an item labeled **Processor**, followed by the name of an Intel processor.

 If you are running Apple Silicon it's highly recommended that you install Rosetta. Many downstream tools still generate `amd64` binaries only, and even if the tools support `arm64`, `asdf` plugins also need to support it, which they may not yet.
 **Note**: You will likely hit many problems unless Rosetta is installed.
