Apple Releases macOS High Sierra 10.13.6 Supplemental Update for 2018 MacBook Pro Models
As we await the launch of macOS Mojave this fall, Apple has quietly released an updated version of macOS High Sierra 10.13.6 that's designed for the 2018 MacBook Pro models.
The new version of the software can be downloaded directly from the Mac App Store or through the Software Update function in the Mac App Store on all compatible Macs that are already running macOS High Sierra.
According to Apple's release notes the update will improve the stability and reliability of the MacBook Pro with Touch Bar, and is recommended for all 2018 machines.
Some 2018 MacBook Pro owners have experienced crackling speakers and issues with kernel panics perhaps related to the T2 chip included in the machines, so it's possible the update addresses some of these issues.
Apple in July released an initial supplemental update for the 2018 MacBook Pro models to address a problem that caused the machines to excessively throttle when doing system intensive tasks. Today's update could also potentially include further refinements to processor performance.
macOS High Sierra is reaching the end of its life as Apple prepares to release macOS Mojave, the newest version of macOS that's currently being beta tested by developers and public beta testers. This is likely to be one of the final updates to the High Sierra operating system.
macOS Mojave introduces multiple enticing new features, such as a system-wide dark mode, dynamic wallpapers that shift throughout the day, Desktop Stacks for organizing desktop files, Finder improvements like a more useful Quick Look view and support for Quick Actions, and new apps like Apple News, Stocks, Home, and Voice Memos.

Why not?
Because the iMac Pro has been dealing with the T2 crashes longer and needs to be addressed as well.

I'm a somewhat gambling man, so I installed the update. No firmware update, so whatever they did is pure software.
There is a firmware update in this. I went from 15.16.6703.0.0,0 to 15.16.6805.0.0,0.

I guess I am lucky with my 2018 MacBook Pro. No issues, no kernel panics, nothing. I feel left out. Now I jinxed myself.

Cinebench went from ~938 to ~990 CPU and ~89FPS to ~92FPS OPENGL. I think this may have included further performance improvements. I'm curious if others see the same.

I'm pretty sure it's for the bridge os error/kernel panics on the 2018 MBP with touch bar. I had been experiencing a lot of them and have been working with a senior advisor and apple engineers for quite a while. I was told last week that a software fix was coming soon to address the issue. I thought they were referring to Mojave but I guess this is it

I wonder if it fixes the Bridge OS error / Kernel panics? Then again if it does, why would this just rollout as a normal update since iMac Pros have the same issue? Hmm.

I wish they came with a hotfix for the 20 sec wake from sleep introduced in 10.13.6.

Just die already. Mojave can't get here fast enough! HS has been a support nightmare for me.
And you honestly believe that a "new" macOS version will fix all the things that the point releases for the current OS version have not fixed...?
The major problem with macOS and also Windows these days is that both platforms are in perpetual beta - and QA and bug fixing are no longer on the agenda.
