Apple has today released iOS 15.4.1, iPadOS 15.4.1, macOS Monterey 12.3.1, watchOS 8.5.1, tvOS 15.4.1, and HomePod Software 15.4.1.
Apple says that iOS 15.4.1 includes the following bug fixes:
- Battery may drain more quickly than expected after updating to iOS 15.4
- Braille devices may become unresponsive while navigating text or displaying an alert
- Made for iPhone hearing devices may lose connection within some third-party apps
The macOS Monterey 12.3.1 release notes say that it fixes the following issues:
- USB-C or Thunderbolt external display does not turn on when connected to Mac mini (2018) as a second display
- Bluetooth devices, such as game controllers, may disconnect from your Mac after playing audio through some Beats headphones
macOS Monterey 12.3.1 also addresses two vulnerabilities, including an AppleAVD issue that could allow an application to execute arbitrary code with kernel privileges and an Intel Graphics Driver issue that could allow an application to read kernel memory.
The release notes for watchOS 8.5.1 simply state that the software brings “bug fixes and improvements.”
Outside of the major upgrade each year, tvOS updates are typically minor in scale with a focus on under-the-hood fixes and performance improvements. As Apple does not provide release notes for tvOS updates, we will have to wait and see if tvOS 15.4.1 does include any user facing changes. We will update this post if anything of note is discovered.
Apple says that HomePod Software version 15.4.1 “addresses an issue where some HomeKit-enabled accessories could fail to respond when controlled via Siri. This update also includes bug fixes for your HomePod.”
Apple has also announced today that the Business Essentials program is now available to small businesses, so it is likely that today's software releases put support in place for this.
