iOS 12.4, iOS 10.3.4, iOS 9.3.6, tvOS 12.4, watchOS 5.3, Apple TV 7.3.1 Updates
Also down the above page are release notes/security fixes for iOS 12.4, iOS 10.3.4, iOS 9.3.6, tvOS 12.4, watchOS 5.3, and 3rd Generation Apple TV 7.3.1 updates.
 

Some think the problems with the original update may have affected T1 and T2 chip Macs. (2016 - 2019 MacBook Pro w/Touch Bar, 2018 Mini, 2018-2019 MacBook Air, 2017 iMac Pro.) I saw several posts that said even an erase and restore from a Time Machine backup made before the update did not solve the problems. (The July 29th rerelease seems to solve that for most.)

(The new release of this update are later macOS build numbers, which means users of Nvidia's web graphics drivers will need another driver update for any user that installs it. Nvidia released new Driver updates on July 30th/31st - see below.)
