MacBook Pro Won't Hibernate Automatically

最近發現手邊的 mbp 16 m1 不管放著螢幕暗掉多久，都可以直接輕觸用指紋打開，感覺沒有進去 Hibernate，不然會需要按一下才能再偵測指紋

先用 pmset -g 確認一下目前的狀態

$ pmset -g
System-wide power settings:
Currently in use:
 standby              1
 Sleep On Power Button 1
 hibernatefile        /var/vm/sleepimage
 powernap             1
 disksleep            10
 sleep                1 (sleep prevented by coreaudiod, powerd)
 hibernatemode        3
 ttyskeepawake        1
 displaysleep         2
 tcpkeepalive         1
 powermode            0

看起來是被 coreaudiod / powerd 影響

再接著用 assertions 確認一下細節

$ pmset -g assertions
2022-10-13 01:22:33 +0800

這邊可以看出來是被 PID: 5501 的 process 影響，查一下該 PID 是 /Applications/LINE.app/Contents/XPCServices/LINE.MediaService.xpc/Contents/MacOS/LINE.MediaService

當下其實 LINE app 已經 quit 掉了，不太確定到底為什麼還有這三個 process

把這三個 process 都 kill 掉之後就正常了！
