Its hard to say. Technically the smcutil
thats included in the app (which does the setting of the value) supports up to 10.12. There is a version of the utility that supports older versions of macOS but I haven't yet figured out how to compile it.
I'm curious as to why its failing. Please try the following:
sudo /Applications/Charge\ Limiter.app/Contents/Resources/smcutil -w BCLM 64
. Modify the path of the Charge Limiter app if its not under the Applications folder.Closed as no response.
Sorry, for some reason I missed the notification that you had responded! Here is the only thing Terminal spits out (and I have confirmed the path to smcutil is correct):
Error: write error
It’s quite possible it’s simply not supported on that older model. Unfortunately I didn’t create the smc utility which does the heavy lifting so I don’t think I’ll be able to add support to your MacBook.
I've tried the script on a 2008 aluminum unibody Macbook running Sierra 10.12.6, but after entering a max charge value I get "There was an error setting the charge limit. Make sure you have administrator privileges." This is with the correct admin password.
This model doesn't officially support Sierra, but I have installed it with DOSDude's macOS Sierra Patcher Tool for Unsupported Macs. Just wondering if there might be a software workaround or it could be a hardware limitation.
