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
2 New Features

4 Enterprise Fixes
14 Security Fixes

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.
