Apple Releases macOS Mojave 10.14.6 Supplemental Update 2

Apple today released a second supplemental update for macOS Mojave 10.14.6, the current release version of macOS that's available to the public.

The macOS Mojave 10.14.6 Supplemental Update can be downloaded by going to the "Software Update" section of System Preferences and selecting the Update Now option. There are also updates available for macOS Sierra and macOS High Sierra.


There's little detail on what's included in today's update, but Apple's release notes say that it "improves the security of macOS" and is recommended for all users. According to a support document, it addresses a vulnerability that could allow remote attacker to "cause unexpected application termination or arbitrary code execution."

The next-generation version of macOS, macOS Catalina, is still in beta testing and is set to see a public release sometime in October, though Apple has not specified when.

Why not just increment the version number to 10.14.7, 10.14.8? It does get confusing when there are multiple release builds out there with the same version number before the next version of MacOS is officially released.

For those who keep track of such details - Mojave 10.14.6 full installer is also updated. This latest update takes the system build to 18G103.

I miss the days when not every update required a restart.

Every 10.14 “update” has broken my 2010 Mac Pro.


I suspect there's something wonky about your installation that is causing this.

I recommend backing up all your data (separately, not as part of a Time Machine backup), formatting the drive down to bare metal/silicon, and doing a fresh from-scratch installation, then restoring your data. This should clean up whatever is hosed on the system that is causing updates to break it.

If so, why make it so close to the release date of Catalina? Most macOS users will not make it to the this Supplemental Update. They don't read Apple-geek blogs.

Some people can't update right away, due to company policy. I know I can't update until I get an "all-clear" email from my IT department.

Isn’t this the third supplemental update?

The previous supplemental update (18G95) is the version 2 of Supplemental Update, and this 18G103 is Supplemental Update 2. Very different.o_O

This must be a serious low level issue as iOS 12 and older watches got an update too.

I think user-level features or emojis substantiate 0.1 increases. System security is supplemental.

Some users may choose to wait before installing Catalina. One reason is that they are still running 32bit apps and are waiting for the vendor to complete their 64bit only release.
