The incremental updates to iOS and iPadOS are minor and aimed at fixing bugs found in iOS 13.6, including an issue that prevented unneeded system files from being deleted when storage is low. The updates also patch a thermal management bug that could cause a green display tint, as well as a problem with Exposure Notification alerts.

According to Apple's release notes, the macOS 10.15.6 Supplemental Update "fixes a stability issue that could occur when running virtualization apps." The issue, present in the App Sandbox caused, problems for virtualization software such as VMware and VirtualBox. Users reported kernel panics and crashing issues.

Additionally, the update resolves a bug that could cause an iMac to appear washed out after waking up from sleep.

“Additionally, the update resolves a bug that could cause an iMac to appear washed out after waking up from sleep.“

I started experiencing this in April. 4 months for Apple to address?

Is Catalina the biggest pile of turds Apple has ever shipped as an OS. Although I’ve skipped a few versions of MacOS over the years, typically the final version of each of them is palatable. It seems this update is pretty darn important for Catalina users but does it finally overcome the caveats I’ve heard over all theses months about “issues” with Catalina. Am I foolish to hope Big Sur will not suffer the same issues?

Catalina was the first I ever skipped. I have it on a work machine so I can support others. Lion was the only other one that might have been as bad. That was the beginning of the end of Server just as we were starting to roll it out. :D

iOS 13 started off pretty bad, especially the iPadOS variant, but I think they did a good job cleaning it up. It's not perfect, nothing ever is, but worth the initial headaches.

This update was the first one that did not require me to unplug/replug my second monitor to get it to be recognized. However, it did not retain my 90 degree rotation on the second monitor so it was not "perfect." Otherwise, let's wait and see how it goes...

I have had zero significant problems in Catalina, having upgraded from Mojave I think around February.
