Apple recently released iOS 13.4.1 to fix a bug relating to FaceTime which would not work when iOS 13.4 devices were calling older devices without iOS 13.4. This issue also affected macOS Catalina 10.15.4, causing significant inconvenience for users who rely on FaceTime for communication.
This new software update is a supplemental update and it is designed to fix the issue with FaceTime calls between the Mac and other devices. You can see what is included in the update below.
Details of the macOS Catalina 10.15.4 Supplemental Update
Here is what is included in the update:
– Fixes an issue where Mac computers running macOS Catalina 10.15.4 could not participate in FaceTime calls with devices running iOS 9.3.6 and earlier or OS X El Capitan 10.11.6 and earlier
– Resolves an issue where you may repeatedly receive a password prompt for an Office 365 account
– Fixes an issue where MacBook Air (Retina, 13-inch, 2020) may hang in Setup Assistant or when disconnecting and reconnecting a 4K or 5K external display
– Resolves an issue where a USB-C port in your Mac may become unresponsive
The new macOS Catalina 10.15.4 supplemental software update is now available to download for the Mac, and it also comes with some other bug fixes.
Additional Context and Impact
The FaceTime bug was particularly problematic as it hindered communication between users on different versions of Apple’s operating systems. FaceTime is a crucial tool for many, especially in times when remote communication is essential. By addressing this issue, Apple ensures that users can continue to rely on FaceTime for seamless video and audio calls across different devices and operating system versions.
The update also addresses a recurring password prompt issue for Office 365 accounts. This bug was a source of frustration for many users who rely on Office 365 for their professional and personal email and productivity needs. By resolving this issue, Apple has improved the user experience for Office 365 users on macOS Catalina.
Another significant fix in this update is for the 2020 MacBook Air. Users reported that their devices would hang during the Setup Assistant process or when disconnecting and reconnecting 4K or 5K external displays. This issue could disrupt the initial setup of the device and affect users who use high-resolution external monitors for work or entertainment. The supplemental update ensures that these users can set up their devices smoothly and use their external displays without any problems.
The unresponsive USB-C port issue was another critical bug that needed addressing. USB-C ports are essential for connecting various peripherals, including external storage devices, displays, and power adapters. An unresponsive port can significantly hinder a user’s ability to use their Mac effectively. By resolving this issue, Apple has ensured that users can continue to use their USB-C ports without any interruptions.
Overall, the macOS Catalina 10.15.4 supplemental update is a crucial release that addresses several significant bugs and improves the overall stability and usability of the operating system. Users are encouraged to download and install the update to benefit from these fixes and enhancements.
