You can switch back to the standard Touch Bar controls whenever you want. Core-Monitor requires macOS 13 or later. It has no account requirement, advertising, or telemetry. Website and download: <a href="https://offyotto.github.io/Core-Monitor/" rel="noopener noreferrer">https://offyotto.github.io/Core-Monitor/</a> Source code: <a href="https://github.com/offyotto/Core-Monitor" rel="noopener noreferrer">https://github.com/offyotto/Core-Monitor</a> There is also a sandboxed Mac App Store edition. Because of Apple sandbox restrictions, that edition is read-only and does not include direct sensors, fan control, or Touch Bar widgets. I would especially appreciate feedback about sensor accuracy, fan controls, and the Touch Bar layout.</li> </ul> showdev swift opensource
