Project Deets

This tool gets inspiration from socpowerbud.
Socpowerbud is unable to get ANE data and contains many functions I don't need. So I wrote this tool.
If you dont want to run by yourself, move to Discussions to get the data.

Example Output

Note: The following is a complete output running on a M1 Max 14" Macbook Pro.
