Here’s my current powersave script that reduces idle power usage from 9 Watts to 7.0W. I am fine with this and ready to search, ask and make extra steps to achieve low idle power usage) (It is indeed largely eroded as I can use all the devices in the laptop even though the out-of-the-box experience is close but do not reach what macos provided about 8 years ago). On the other hand years passed and this inbalance towards macos should have been eroded. Arch linux macbook pro retina mid 2014 software#I understand that mac software and hardware is very closely tied and information on this is somewhat walled. Idle macos uses 3.2 Watts, while idle Linux uses 8-9 Watts. removing all pci (subsequently usb) devices via sysfs (except vga and host:dram).On linux these did not or marginally lower power usage: Similar measurements on a 4GB 2015 macbook air. ![]()
