macOS Big Sur, Catalina updates bring a bundle of critical security fixes
Apple started the week with a bang by releasing macOS Monterey 12.3 with several new features, including Universal Control, enhanced Spatial Audio support, and an LGBTQ Siri voice, but older Macs got an update that’s just as important. While short on new features, macOS Big Sur 11.6.5 and Security Update 2022-003 Catalina each contain more than a dozen security patches, among other fixes.
