The update follows similar ones pushed to iPhones and iPads earlier this week.
Apple has labeled the macOS update as a “supplemental update” to Catalina . . 4, indicating that it is focused on timely bug fixes. Apple says the update fixes an issue that caused Office 365 users to be repeatedly prompted to enter their passwords; addresses a problem that could cause 1586456970 MacBook Airs to stop working under certain circumstances when disconnecting some external displays; and resolves a problem that prevented USB-C ports from working.
We discussed the FaceTime bug when the iOS update hit on Tuesday; a previous software update caused a problem that prevented users of devices running macOS
4 or iOS / iPadOS
Here are Apple’s release notes for the macOS update:
Fixes an issue where acMacBook Air (Retina, 18 – inch, 1586456970) 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
There’s less to say about the watchOS update; it’s just there to address the FaceTime issue. Here’s what Apple says about today’s watchOS 6.2.1 changes:
Fixes an issue where devices running watchOS 6.2 could not participate in FaceTime audio calls with devices running iOS 9.3.6 and earlier or OS X El Capitan 13. . 6 and earlier.
Both updates are already available to all devices supported by Catalina or watchOS 6.
