bclm

Set a custom charge limit on MacBooks. More information: https://github.com/zackelia/bclme.

Set the charge limit to about 80% (for Intel machines, the battery charge level may be slightly lower than the set value):

sudo bclm write {{77}}

Read the current charge limit:

bclm read

Keep the charge limit after rebooting/smc reset:

sudo bclm persist

Remove the persistent charge limit:

sudo bclm unpersist
