Apple has released a macOS Catalina 10.15.5 Supplemental Update which includes important security fixes. Here's how you can download it now.

Today is a weird and wonderful deal for software enthusiasts. Apple released a bunch of new software, including iOS 13.5.1 / iPadOS 13.5.1, tvOS 13.4.6 and watchOS 6.2.6, while seeding new beta software to developers, including iOS 13.5.5 / iPadOS 13.5.5 and macOS 10.15.6. For jailbreak users came bad news as the new update patches Unc0ver. But the news does not end there as Apple has seeded the macOS Catalina 10.15.5 Supplemental Update for every Mac user out there with important security fixes.
