Apple has officially released the new iOS 26.5.1 and macOS 26.5.1 updates for iPhone and Mac users. The latest software releases are maintenance-focused updates aimed at fixing critical bugs and improving overall device stability.
Although the updates do not introduce any major new features, Apple says they resolve important issues affecting charging performance on select iPhone models and unexpected shutdowns on Mac devices powered by the latest M5 chip.
iPhone Charging Bug Fixed in iOS 26.5.1
According to Apple’s official changelog, some users of iPhone Air and iPhone 17 models were facing a charging issue when their devices had extremely low battery levels.
The company explained that in certain cases, affected iPhones failed to charge properly through wired chargers once the battery was nearly depleted. While Apple noted that only a small number of users experienced the issue, the problem could create serious inconvenience during emergency or low-power situations.
With the rollout of iOS 26.5.1, Apple says the charging-related bug has now been fully resolved.

According to the company, some M5 Mac systems were unexpectedly shutting down while using content filtering network extensions. The issue mainly impacted enterprise users, IT administrators, and professionals relying on advanced network security or filtering tools.
Apple confirmed that the bug has now been fixed with the latest macOS 26.5.1 update.
The update is considered especially important for professional environments where unexpected system shutdowns could disrupt workflows, business operations, or cybersecurity processes.
