Towards the end of the week, Apple issued 2 small updates for iOS 13 and macOS Catalina. The updates seemed to only fix very particular issues on very particular devices.

On the Mac, we got a fix for the latest 27-inch iMac fixing a washed out color issue when the Mac wakes from sleep, as well as a more general Catalina fix for shoring up stability when running VMs and other virtualization tools. Full patch notes are below.
