Exploring Your Apple M1 devices with Open Source Tools

演講摘要

This talk will be an updated and extended MacOS M1 version of my previous talk on getting iDevice thermal sensors [1]. Since a macOS device comes with root already, getting non-trivial information on M1 devices is much easier than on A14 devices. I'll talk about:

  1. thermal sensors on without root [2]
  2. further thermal sensors you can get with root and SIP disabled, such as [3]
  3. how get similar information by using IOKit functions [4]
