操作一
查看自己電腦的休眠狀態，改成25可以解決待機耗電的問題
pmset -g
sudo pmset -a hibernatemode 25
以下是蘋果電腦的幾種休眠狀態，
hibernatemode=0
by default is supported on desktops. The system will not back memory up to persistent storage. The system must wake from the contents of the memory (RAM). The system will lose context on power loss. Historically, this is plain old sleep.
sudo pmset -a hibernatemode 0
hibernatemode=3
by default is supported on portables or laptops. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image.
sudo pmset -a hibernatemode 3
hibernatemode=25
is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want hibernation—slower sleeps, slower wakes, and better battery life you should use this setting.
操作二
- 藍牙偏好設置 /高級 /去掉勾選「允許藍牙設備喚醒這台電腦」
- 系統偏好設置 /節能 /電源適配器下， 去掉勾選「喚醒以供 Wi-Fi 網絡訪問」
- 系統偏好設置 /節能 /電池下，先勾選「電池供電時啟用 Power Nap 」，再去掉勾選該選項，此舉為了解決 macOS 存在的可能性的 Bug，看似未勾選，實際上是勾選的可能性存在的 Bug。這個 Bug 會導致在用電池睡眠的時候依然在定期喚醒訪問 Wi-Fi。
- sudo pmset -b tcpkeepalive 0 設置在電池供電的情況下，關閉網絡訪問。
