Two weeks after releasing the macOS Catalina 10.15.4 update to its traditional computers, Apple has released the macOS Catalina 10.15.4 supplemental update. The new software update can now be downloaded and installed from the Mac App Store for free.
Apple has just released the supplemental macOS Catalina 10.15.4 update for compatible iMacs, iMac Pros, Mac Minis, Mac Pros, and MacBooks. All the users with Macs running macOS Catalina can download the software update from the System Preferences app. Apple had also released watchOS 6.2.1 with bug fixes to compatible Apple Watches earlier today.
The new software fixes the bug that caused problems when macOS Catalina running machines were unable to participate in FaceTime calls with Macs running OS X El Capital 10.11.6 (or earlier) and iPhones running iOS 9.3.6 (or earlier). The official changelog that comes with the latest update claims that Apple has also resolved an issue where users were repeatedly receiving password prompts for Office 365 accounts.
Apple has also solved an issue that forced the 2020 13-inch MacBook Air to freeze when disconnecting and reconnecting to an external 4K or 5K display or when running the Setup Assistant. The new macOS update has also fixed an issue where USB Type-C ports on Macs were becoming unresponsive.
The macOS Catalina 10.15.4 operating system update, which brought real-time lyrics in Apple Music and Screen Time Communication Limits, could be the last version in the series. Apple is readying itself to unveil macOS 10.16 during WWDC 2020, which is set to happen in June 2020.
The Cupertino-based company is also expected to announce iPadOS 14, iOS 14, tvOS 14, and watchOS 7 during its developers’ conference.
