Yes, I wrote this guide after installing and setting up Appium on an M1 Macbook Air.

Just to confirm, do you have NodeJS 16.X installed and the latest version of npm? The reason I ask is because the terminal output you shared shows the npm pre-install dependency audit warning. When this warning raised, the install process won't go through, thus why you don't see the appium folder in your global node_modules directory.

To troubleshoot, I'd consider the following:

- Ensure that you have NodeJS 16.X installed

- Verify that you have the latest version of npm. You can always download the latest version of npm by running: npm install -g npm

- Try a specified install with the latest version of appium available in npm: npm install -g appium@1.22.1
