Catalina Beta Includes ‘Pro Mode’ for Mac Notebooks »

Filipe Espósito, at 9to5Mac:

The latest macOS Catalina 10.15.3 beta build contains references to a new “Pro Mode,” which can be turned on and off by users. Some strings mention that “Apps may run faster, but battery life may decrease and fan noise may increase” and “Fan speed limit overridden” when the Pro Mode is activated.

As these strings are directly related to the macOS power management system, we think that it will be possible to temporarily improve the machine’s performance by ignoring some restrictions to save energy. The internal fans will run at a higher speed with Pro Mode, probably to avoid thermal throttling issues. Similar to Do Not Disturb, Pro Mode is supposed to be automatically disabled by the next day.

This seems cool, but it makes me wish for better thermals across the MacBook line.
