Appleは月曜日にiOS 26.5および各オペレーティングシステムのアップデートを公開し、iPhoneとAndroidユーザー間のRCSチャット向けにベータ版のエンドツーエンド暗号化を追加した。
今回のアップデートでは、RCS会話が保護されていることを示す鍵アイコンが追加され、米国ではAT&T、T-Mobile、Verizonなどの対応通信キャリアで利用可能となる。Appleによると、暗号化はデフォルトで有効になっており、新規および既存のチャットに対して順次適用される予定だ。ただし、現在はベータ版の扱いで、Android端末側には最新のGoogleメッセージアプリが必要となる。
X上での初期反応は、AppleのiOS 26.5アップデートによるベータ版エンドツーエンド暗号化RCSメッセージングの導入に対し、概ね肯定的かつ中立的である。ユーザーからは、プラットフォーム間のプライバシー向上やアップデートの推奨、対応キャリアでの機能提供に関する言及が見られるほか、ベータ版であることに留意しつつも、iMessageとの差が縮まることへの期待の声が上がっている。

Tesla's plans to add Apple CarPlay to its vehicles have been delayed by a compatibility issue between Apple Maps and its own navigation software during autonomous driving. The company requested engineering changes from Apple, which were implemented in a later iOS 26 update, but slow adoption of the software prompted a pause. With iOS 26 now on 74% of recent iPhones, Tesla may accelerate the rollout.
