I think this might be the fastest patch of a security issue affecting Apple's operating systems, ever. Aside from *.0.1 releases that fixed critical bugs with core features in new OSes, has anything been patched this fast?

(I'm also obligated to post that the bug that this fixes is not new; it was discovered back in iOS 11, fixed, and Apple reopened it in an iOS 13 update: https://www.synacktiv.com/posts/exploit/return-of-the-ios-sa...)

From the equivalent macOS patch: https://support.apple.com/en-us/HT211215 > Available for: macOS High Sierra 10.13.6, macOS Catalina 10.15.5 That's interesting—did the bug exist on both 10.13 and 10.15, but not 10.14?

Yes: it was fixed for that period and then rebroken for Catalina.
