Charge limiting on MacBook Pro

gq flag

I'm setting up my old MacBook Pro as a Time Machine Server with ubuntu, and was wondering whether someone managed to do charge limiting on a Mac. This thread has some answers, none of them are Mac-specific though, and I believe this is a hardware-specific thing...

Thank you in advance!

The battery is 100% managed by the UEFI on Intel-based Apple hardware, and only MacOS can interface with the UEFI APIs to make changes

I've accidentally solved this by setting a charge limit using bclm before installing Ubuntu. After the installation, the macOS partition is wiped, but the charge limit persists (in the MacBook's SMC) - at 80% capacity, Ubuntu tells me my battery is full and won't charge!

I can't change the charge limit anymore, but I want the laptop to run on the charger anyway ;)

Now let's hope the SMC doesn't get reset...

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
