CHARSETファイル、またはその他の文字セットファイルとして知られているが、現在のMac OS Xアプリケーションで使用され、リソースと呼ばれるフォルダに格納されています。アップルテキストエディットなどのテキストエディタでは文字セットでリビジョンを変更したりするために使用することができます。 Mac OSののテキストエディットは、さまざまなタスクを行うことができ、ワードプロセッサプログラムです。ユーザーは、基本的に彼らが望む任意のテキストドキュメントを作成することができます。これにより、ユーザーは形式の文書に使用できるツールがあり、任意のページのレイアウトを配置することで、迅速かつ簡単です。また、テーブルを作成するリストを作成し、グラフィックスがHTMLでうまく動作することができ、インポートなどが追加の多彩な機能には、ユーザーが文書上の音楽や動画編集を含めることができます。これは、単純にすべてのユーザーが作業している文書にドラッグすることによって行われます。説明を追加することも許可して、言葉を入力するときはいつでも、便利なチェックスペルチェックを使用すると、入力しているものを監視して、赤の点線でスペルミスを強調している。
Apple TextEdit is a text editor program and an open-source word processor too, which is first used in NeXTSTEP and OPENSTEP, but now integrated in most recent versions of Mac OS X. It is also considered a GNUstep application for other operating systems that are Unix based, like Linux computers. This program is operated by Advanced Typography by Apple so expect several advanced typography related features. The main function of this software is to read and write documents in plain text, HTML formats, Rich Text Format, and Rich Text Format Directory. It can also open Simple Text files but does not have the capability to save documents of that format. Mac OS X version 10.3 supports Microsoft Word documents, while Mac OS X version 10.4 can open and save Word documents in XML file. Mac OS X version 10.5 is able to read and write Office Open XML as well as OpenDocument Text. Features included on TextEdit are formatted text support, addition of graphics, animations and other multi-media contents, automatic adjustment of letter spacing, as well as reading and writing support of character encodings.
