Linux Kernel Patches Promise Battery Gains for Aging 2018 MacBook Pros
Submitted by Anonymous (not verified) on Thu, 08/13/2026 - 13:02Years after Apple stopped selling them, a set of 2018 and 2019 MacBook Pro models may soon run Linux with markedly better battery life. Patches posted this week to the kernel mailing list tackle a stubborn power drain that has plagued these Intel-based laptops.
The work targets Apple’s GMUX hardware. This component switches between the integrated Intel graphics and the discrete AMD GPU. Without proper support, Linux boots with the AMD chip active. The result wastes power even during light tasks.
