Apple today released a MacBook Pro Supplemental Update for 2018-19 T2 15″ MacBook Pros.

Update 05/24/19 9:00AM: I have updated this article to include BuildVersion info and Apple Download Links. I will continue to add more information when I find it.

The MacBook Pro Supplemental Update is specifically targeted at 15″ 2018 & 2019 T2 MacBook Pros with 10.14.5. The update does NOT show up as available for 10.14.4 and lower OS versions. The update weighs in at 946.8mb.

UPDATE: After the update is installed the BuildVersion number will be (18F203). BridgeOS will also be updated and listed as 16.16.5200.0.0,0.

This update is only available for boardID’s Mac-937A206F2EE63C01 MacBook Pro (15-inch, 2018) & Mac-1E7E29AD0135F9BC MacBook Pro (15-inch, 2018) with a Vega ATI Graphics card. Looks like the 2019 models share the same boardID’s.

Apple also released a new 10.14.5 macOS Installer.app, the BuildVersion is (18F203).

UPDATE: The (18F203) Install macOS Mojave .app installer is so far seems to be for 2018 15″ T2’s. I have gone through the boardID’s of 10.14.4 install.app and 10.14.5 18F203 and found no new board id’s that would identify the new 2019 MacBook Pros.

10.14.5 (18F203)

This update weighs in at 6.51gb and has a Product ID number of 041-64745. You will be only able to download this installer if you are using a 2018 or 2019 15″ T2 MacBook Pro.

I ran some more tests trying to download the Install macOS Mojave.app (18F203). It seems you have to be on a 2018 15″ MacBook Pro to get the download. To get it from the App store you have to be on 10.14.5 and on a 2018-19 15″ T2. If you are on any anything else and you are get the (18F132) BuildVersion. For installinstallmacos.py you have to be on a 2018 15″ T2 but can be on an OS lower than 10.14.5. I tested this with a 2018 15″ T2 on 10.14.4 and was able to use installinstallmacos.py to down download the .app (18F203) installer. But the build failed on a 10.13.6 2018 15″ T2. Also the boardID list for (18F203) is exactly the same as (18F132), so it doesn’t seem to be a 2019 MacBook Pro Fork.

Is 10.14.5 (18F203) a hybrid fork?

Is the 10.14.5 (18F203) installer.app a hybrid fork or was it an error on the installer compatibility list ? Meaning I can only download this installer if I am on a 2018-19 15″ T2, but once downloaded I can install this version of the installer on any 10.14 compatible Mac.

MacOS System Status & Version Info

I am keeping track of all this on my macOS System Status & Version info page. This page was designed to help you keep up to date with the latest versions of macOS software and core applications.

Apple Intros New 2019 MacBook Pros, Includes New Revised Keyboard

Mr. Macintosh - New 8-Core 2019 MacBook Pro. 13" & 15" Touch Bar Models are new.
New 8-Core 2019 MacBook Pro. 13″ & 15″ Touch Bar Models are new.

Apple in a surprise launch ahead of WWDC19, releases new 2019 MacBook Pros with a new revised keyboard design. Apple also expanded the Keyboard Service Program to add the 2018 MacBook Pro & Air.

In a move, most did not see coming a new 2019 MacBook Pros were released today. The big news is how the MacBook Pro is getting an 8-Core CPU for the first time. The real news you want to know about probably involves the keyboard. Was it redesigned? Has the mechanism changed? We know one answer was confirmed by Apple though TheLoop.

Another change in the newest MacBook Pro computers is with the keyboard. While Apple says the vast majority of its customers are happy with the keyboard, they do take customer complaints seriously, and work to fix any issues.


To address the problem, Apple said they changed the material in the keyboard’s butterfly mechanism that should substantially reduce issues that some users have seen.

Apple also told me that any problems with the butterfly keyboard on any of its MacBook Pros would be covered at no cost to the customer. The company has also taken steps to improve the repair process, shortening the time it takes to make repairs to the keyboards.

“Updated” 3rd Generation Keyboard?

John Gruber @daringfireball.net dug in further when he spoke with Apple.

First, these new MacBook Pros still have the third-generation butterfly-switch keyboard that debuted with last July’s updated MacBook Pros. But Apple has changed the mechanism under the hood, using a new material for at least one of the components in these switches. The purpose of this change is specifically to increase the reliability of the keyboards. Apple emphasized to me their usual line that the “vast majority” of users have no problem with these keyboards, but they acknowledge that some users do and they take it very seriously.

2017 MacBook Pros with 3rd Gen Keyboard can get new revised replacement.

From the Verge

According to The Verge, some existing MacBook Air and MacBook Pro models that experience keyboard failures will have their keyboards replaced with the new 2019 keyboard that Apple has developed. Unfortunately, only MacBooks with the third-generation butterfly keyboard can get the updated 2019 keyboard, which includes the 2018 MacBook Pro and the 2018 MacBook Air.

Testing the new 2019 MacBook Pro.

I will try to get my hands on one of these new 2019 MacBook Pros as soon as possible. Looks like the earliest they can be had is Thursday May 23rd.

Forked version of macOS Mojave 10.14 ?

You can almost bet 100% that the new 2019 MacBook Pros will have a forked build of 10.14 on it. Checking Apple’s catalog nothing has shown up yet. I will update when I have more info.
