回答:
最近同じ質問があり、brew経由でインストールできるコマンドラインツールwww.smartmontools.orgを見つけました。
brew install smartmontools
その後、それを実行できます
smartctl -a disk0s3
disk0s3ドライブの情報を取得することにより、Disk Utility.appで見つけることができるディスクの物理的なバッキングはどこにありますか。（OS Xのコマンドラインでこれを見つける方法が必要です。）出力の例を次に示します。

Lee Joramoの優れた回答を拡張すると、GSmartControl GUIをにインストールできますsmartmontools。Homebrewタップで提供されます。
手順は次のとおりです。
brew install smartmontools
brew install gsmartcontrol
gsmartcontrol
ところで：私は最初にSMARTを有効にする必要がありました。GUIはあなたのためにそれを行うことができます。コマンドラインを使用する場合はsmartctl -s on -a disk0s2です。
まったく新しく、MacOS Sierra、Yosemite、El Capitanオプションと互換性があります：
https://sourceforge.net/projects/smartmontools/からネイティブのプリコンパイル済みパッケージを取得し ます
それをインストールし、ターミナルを開いて実行します：
sudo /usr/local/sbin/smartctl -a /dev/disk0
次のような完全な出力が得られます。
