AppleがiPad向けiPadOS 17.7.8をリリース!

Appleは19日(現地時間)、同社が展開するタブレット「iPad」シリーズ向けプラットフォーム「iPadOS」において前バージョン「iPadOS 17」の最新版「iPadOS 17.7.8(21H440)」を提供開始したとお知らせしています。

対象機種は最新バージョン「iPadOS 18」に対応していないiPadOS 17の対応機種で、具体的にはiPad(第6世代)や12.9インチiPad Pro(第2世代)、10.5インチiPad Proの3機種となります。なお、以前は「iOS 18」やiPadOS 18の対象機種はiOS 18やiPadOS 18またはiOS 17やiPadOS 17を選んで更新できていましたが、iPadOS 17.7.3からiOS 18やiPadOS 18の対象機種はiOS 18やiPadOS 18のみに更新するようになっています。

変更点は重要なセキュリティーアップデートが含まれているとされていますが、現時点ではどういった脆弱性なのかは明らかにされておらず、CVEに登録されている脆弱性についても掲載されていませんが、前回のiPadOS 17.7.7が不具合で提供を停止していたため、恐らくその不具合を修正した上でiPadOS 17.7.7と同じセキュリティーアップデートが実施されているのではないかと思われます。

Appleでは2021年に提供開始したiOS 15およびiPadOS 15から一定期間は次の最新バージョンに更新せずに既存のバージョンに留まる機能を提供しており、今年も最新のiOS 18やiPadOS 18の正式版が配信開始されましたが、引き続いてしばらくiOS 17やiPadOS 17で使う場合を対象にセキュリティー修正のみを行ったソフトウェア更新を提供しており、今回は前回のiPadOS 17.7.7に続いてiPadOS 17.7.8が提供開始されました。

更新は従来通り各製品本体のみでOTA(On-The-Air)によりダウンロードで行え、方法としては、「設定」→「一般」→「ソフトウェア・アップデート」から行え、単体でアップデートする場合のダウンロードサイズは手持ちのiPad(第6世代)でiPadOS 17.7.6からだと459.2MBとなっています。またiTunesをインストールしたWindowsおよびMacとUSB-Lightningケーブルで接続しても実施できます。なお、Appleが案内しているアップデートの内容およびセキュリティーコンテンツの修正は以下の通り。
