Apple may be preparing to release a new macOS feature called 'Pro Mode,' according to a recent report from 9to5Mac. Evidence of the feature was found nestled within macOS Catalina 10.15.3 beta code alongside strings of text. Based on the text, it seems 'Pro Mode' will be a manual feature that enables users to temporarily boost a Mac's performance.

Apple releases beta versions of its macOS operating system for developers to test before the updates are made available to casual users. Teardowns of these updates may reveal the presence of unannounced features that are hidden in the code, the latest example being this newly detailed 'Pro Mode.'

Strings of text listed as descriptions of the feature state that enabling Pro Mode may make apps 'run faster, but battery life may decrease and fan noise may increase.' As well, a string of text reveals that 'fan speed limit [is] overridden' when Pro Mode is active.

The report indicates that users may be able to turn Pro Mode on manually and that the system will automatically disable it by the next day in a way similar to the existing Do Not Disturb feature. The feature is expected to be made available on MacBook laptops, making it possible for users to temporarily boost performance while editing images, processing videos or other tasks with more demanding requirements.
