Does it work on Linux? about charge-limiter HOT 2 OPEN

The underlying CLI program uses Apple's SMCKit library/framework, so no that won't work on Linux I believe.

A Linux kernel driver for the SMC is required for this sort of thing to work, so I'd start looking into that.

from charge-limiter.

tl/dr: Good question! It might be worthwhile to try a temporarily boot to 10.14, like from external usb, and run Charge Limiter in 10.14. Then, If lucky, when booted back to linux the battery may not charge above the limit set in 10.14. I say this because it works for me when booting 10.13, where charge-limiter cannot be run, as detailed below.

... Details of my possibly flawed reasoning.... Since the limit is stored in nvram (not anywhere on disk storage), I think when linux is running, perhaps the charge limit might still be in effect. I have not tested in linux(yet) but if I have time will test in linux and update this posting with results. The reason I thiink it is worth a try is based on what I see with a dual-boot mac laptop: 10.13 or 10.14. I set the limit to 80% in 10.14, and when I boot to 10.13, the battery does not charge above 80% or so. The charge-limiter 1.5.1 currently does not run on 10.13 or earlier (tho I tried, below). In 10.13 when launched, after about a second it displays error below about bclm (bclm is the The underlying CLI program uses Apple's SMCKit library/framework,

P.S. My first try to compile bcim that might run on 10.13 failed as shown below... (I have the command-line tools but maybe I need full xcode???)
