Apple released updates for iPadOS and iOS to fix a bug prevented devices running the latest software from joining FaceTime calls with some older devices.
Now, Apple has done the same with macOS but the macOS update includes a few additional fixes, too.
Apple has labeled the mac-OS update as a supplemental update to Catalina 10.15.4, indicating that it’s focused on timely bug fixes. Apple says the update fixes a haul that caused Office 365 users to be repeatedly prompted to enter their passwords; addresses a haul that might cause 2020 MacBook Airs to stop working under certain circumstances when disconnecting some external displays; and resolves a drag that prevented USB-C ports from working.
We discussed the Face-time bug when the iOS update hit on Tuesday; a previous software update caused a haul that prevented users of devices running mac-OS 10.15.4 or iOS/iPad-OS 13.4 from communicating via Face-time with users running iOS 9.3.6 or OS X 10.11.6.
MacOS Catalina 10.15.4 supplemental update improves the stability and security of your Mac.
- 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
