[macOS10.15]hibernatemode ハイバネートモード

Manの内容

hibernatemode = 0 by default on desktops. The system will not back memory
up to persistent storage. The system must wake from the contents of mem-

ory; the system will lose context on power loss. This is, historically, plain old sleep.

hibernatemode = 3 by default on portables. 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 hibernate image.

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 "hiberna-
tion" - slower sleeps, slower wakes, and better battery life, you should
use this setting.

デスクトップは０推奨
ノートは３推奨
メモリ内容をデイスクに書き出し電源断する２５
バッテリーが厳しくなってきた機器の場合は２５が良いでしょう
