  • That thread was a godsend. Turning off tcpkeepalive was the other one that I couldn’t remember, but that seemed to help out as well.

    My wife has had multiple MacBooks over the years (I set up her old 2009-era A1278 with Linux Mint for the kids to do homework), and after I “fixed” it and talked about the longer wake-up process, she told me that’s what she was used to already and the “super fast wake up” was a very new thing for her when she bought it. So no complaints from her, and the battery performs better. Win/win.




  • So here’s the thing - if you can think of it, I’ve already tried it 😅 I spent a week and a half sifting through countless forum posts on Apple’s own support center, Macrumors, reddit, and a host of other forums.

    The “Wake for network access” setting was the first thing I disabled after I wiped and reinstalled the OS. Among a number of other settings, including “Power Nap”. Still got the fucking “EC.DarkPME (Maintenance)” process firing off every ~45 seconds, no matter what I did, causing excessive insomnia and draining the battery within 12 hours.

    What I ended up doing was using a little tool called “FluTooth” to automatically disable wifi/Bluetooth on sleep (the built-in OS settings did fuck-all), set hibernationmode to 25, and a few other tweaks with pmset that currently escape me (edit: disabled networkoversleep, womp, ttyskeepawake, powernap - which was still set to 1 even with the setting in System Settings was disabled 🤨), and a couple others I can’t remember as it’s not here in front of me).

    I put several full charge cycles on the brand new battery before it finally calmed the fuck down.


  • As someone who just had to bandaid an unexplained battery draw on his wife’s MacBook - no, Mac OS no longer “just works”. Apple buries some of the most basic settings inside a command line-only tool called pmset, and even then those can be arbitrarily overridden by other processes.

    And even after a fresh reinstall and new battery, it still drains the battery faster in hibernation mode than my Thinkpad T14 G1 running LMDE does while sleeping. Yeah, that was a fun discovery.

    That Thinkpad is by far one of my most dependable machines.
