概要
iTerm2は、macOS向けのオープンソースターミナルエミュレーターです。標準のmacOS「ターミナル」アプリの代替として設計されており、元々2009年にiTermの後継として開発されました。開発者はGeorge Nachmanで、「ターミナルを現代的な時代へ導き、あなたが常に欲しかった機能を提供する」というコンセプトのもと継続的に機能拡張が行われています。現在はmacOS 12.4以上に対応しており、バージョン3.x系として活発にメンテナンスされています。
主要な特徴・機能
- 分割ペイン: 1つのウィンドウを縦横に分割して複数のターミナルセッションを同時表示
- インスタントリプレイ: 過去のターミナル出力履歴をタイムスタンプ付きで巻き戻して確認できるDVR機能
- シェルインテグレーション: シェルプロンプトを認識してコマンド履歴のナビゲーションやディレクトリ履歴管理を実現
- スマートセレクション: URLやファイルパス、メールアドレスなどのセマンティックオブジェクトを4回クリックで選択
- コピーモード: Vimライクなキーボード操作でマウスなしにテキスト選択が可能
- トリガー: 正規表現パターンにマッチした際にテキストハイライトやコマンド実行、通知送信などのアクションを自動発火
- ステータスバー: gitブランチ、CPU/メモリグラフ、カレントディレクトリなどをカスタマイズ可能なステータスバーを表示
- AIチャット機能: ターミナル内容と連携できる組み込みLLMチャットウィンドウ
- Exposéタブ: 開いているすべてのタブをサムネイル表示で一覧確認
- ホットキー起動: 特定のキーコンビネーションを押すだけでどこからでもターミナルを即時起動
- オートコンプリート: 過去のコマンド履歴に基づいた候補を自動サジェスト
- Growl/通知センター対応: 長時間実行コマンドの完了をデスクトップ通知で受け取れる
対象ユーザー
- ターミナルで多くの時間を費やす開発者・システム管理者
- 複数のサーバーやサービスを並行管理するエンジニア
- Vimやtmuxなどのキーボード中心のワークフローを好むユーザー
- 生産性向上のためにターミナル作業の効率化を求めるmacOSユーザー

Version 3.7.3 of iTerm2 was built on September 22, 2026.
Bug Fixes:
- Fixed the Python API not reporting OSC 8
hyperlinks. A cell’s CellStyle.url is now
populated, so scripts reading screen contents
can see the link target.

Profiles > Window. Choosing “Main Screen”
left the popup blank and showed no checkmark
next to it when reopened, although the
setting was saved correctly.

whose web address contained an emoji or other
character outside the Basic Multilingual

Version 3.7.1 was built on September 10, 2026.
Improvements:
- Newlines embedded in a completion suggestion
(such as a command-history entry or file name)

The value inserted when you accept the row is
unchanged.
Bug Fixes:
