MacOS High Sierra Supplemental Update 2 Released for MacBook Pro 2018 Users
Apple has released a new supplemental software update for owners of the 2018 model MacBook Pro with Touch Bar. The software update is limited to the 2018 model line, so if you have a different Mac you will not find the software update available on other machines.
Labeled as “macOS High Sierra 10.13.6 Supplemental Update 2 for MacBook Pro (2018)”, the update is said to improve “the stability and reliability” of the computer, and is therefor recommended for all users of a 2018 MacBook Pro with Touch Bar to install.
If you currently own a 2018 MacBook Pro with Touch Bar and it is running macOS High Sierra (10.13.6), you can find the supplemental update available to download now from the software update mechanism within the Mac App Store Updates section.
Alternatively, you can get the High Sierra Supplemental Update 2 for 2018 MacBook Pro from support.Apple.com here
If you download the supplemental High Sierra update directly, it weighs in around 1.3 GB.
It’s not entirely clear what is included in “macOS High Sierra 10.13.6 Supplemental Update 2 for MacBook Pro (2018)” but there is some speculation the particular software update might aim to address some reported stability issues that are specific to the machine. It is unclear if the supplemental update improves keyboard reliability, though that is perhaps less likely given the nature of keyboard issues.
Release notes accompanying the software update are vague, without offering any specific about what exactly is addressed with the supplemental update:
The macOS High Sierra 10.13.6 Supplemental Update 2 improves the stability and reliability of MacBook Pro with Touch Bar (2018) computers, and is recommended for all users.

Presumably whatever is included in the High Sierra Supplemental Update 2 is also included in the latest builds of macOS Mojave for the 2018 model year Tough Bar MacBook pro.
The 2018 MacBook Pro with Touch Bar was released in July of this year as a refresh of the existing MacBook Pro model line.
