The final macOS Catalina 10.15.6 update is live! The update is now available for download as a full installer.app, delta and combo update. This update might include a fix for the fix for the MacBook Pro 16″ wake from sleep Kernel Panic Issue! NOTE: as in 10.15.5, the patch notes do not mention this issue. Did 10.15.6 fix the wake from sleep KP issue for you ? Let me know in the comments.
Let’s take a closer look at the final Catalina point release update. When I say final update, I mean that for the past 4 (10.11-10.14) macOS releases Apple has gone to .6. We could see a supplemental update or 2 (Mojave) if a serious defect is found in 10.15.6. Don’t count on this though, as all development is now being put into macOS Big Sur.
10.15.6 Patch Notes Summary

Apple’s Public Patch Notes / Release Notes Documentation
NOTE: Apple Documentation takes a little while to show up online after release. I will update when the new articles are made available.

Apple Reverts softwareupdate –ignore changes from 10.15.5
You might remember my article talking about the changes Apple made in 10.15.5 and the 2020-003 security updates. mrmacintosh.com/10-15-5-2020-003-updates-changes-to-softwareupdate-ignore/. With the Catalina 10.15.6 & 2020-004 security updates, those changes were reverted back. After installing 10.15.6 or the 2020-004 updates, you can once again use softwareupdate --ignore to block minor and major updates. As long as the Mac is enrolled in Apple School Manager, Apple Business Manager or a User Approved MDM.
