The Case for Low Power Mode on the Mac

Marco Arment on marco.org, outlining his self-created Low Power Mode-like system which relies on a third-party app, and making the case for Apple to add something similar as an official macOS feature:

The vast majority of the time I’m using it, the 16-inch MacBook Pro is a much better laptop with Turbo Boost disabled.

It’s still fast enough to do everything I need (including significant development with Xcode), while remaining silent and cool, with incredible battery life.

But soon, I bet I won’t be able to do this anymore.

Turbo Boost Switcher Pro relies on a kernel extension that’s grandfathered into Apple’s latest security requirements, but it can never be updated — and when macOS Catalina loads it for the first time, it warns that it’ll be “incompatible with a future version of macOS.” I suspect that this is the last year I’ll get to run the latest OS and be able to turn off Turbo Boost at will, making all of my future laptop usage significantly worse.

Low Power Mode is one of many useful features that iOS has had for years but that Mac users have been forced to live without. The feature’s popularity on iOS makes it a no-brainer addition for portable Macs, where battery life is already worse than what’s found in the iPhone and iPad.

Update: Former MacStories contributor TJ Luoma helpfully pointed out something that genuinely surprised me: Low Power Mode isn’t on the iPad either. Here’s hoping Apple brings it not only to the Mac, but the iPad as well.
