MacBookでハイパースレッディングを無効にする

Last updated at Posted at 2017-06-26

昨日、SkylakeとKabylakeでハイパースレッディングに問題ありという投稿がありました。
https://lists.debian.org/debian-devel/2017/06/msg00308.html

そこで対策として有効かわかりませんが、ハイパースレッディングを無効にする方法です。

  1. XCodeをインストール
  2. Instrumentsを起動
  3. PreferencesからCPUsタブを選択してHardware Multi-Threadingのチェックを外す

これで無効になるようです。
