Today Apple Released a New Mojave 10.14.5 (18F2058) Forked Full Installer app
UPDATED: 07/10/19
In the past when Apple released a build it would start with a 2 digits followed by a letter. An example of this would be 18F132 which is a unified build of macOS Mojave 10.14.5. Just this morning Apple released new hardware which I covered here. Usually with new hardware comes a specific BuildVersion of the OS.
MacOS Mojave 10.14.5 (18F2058)
To find out if this really was a forked build, I cracked open the OSInstall.mpkg inside the new build. The build is listed as Product ID 041-69971 – 10.14.5 – 18F2058 and was released on 2019-07-09 (Today). Inside you will find the Distribution file. Inside this file you will find all the compatible boardIDs for this build. After comparing both Distribution files two new board ID’s popped up.
- Mac-53FDB3D8DB8CA971 = MacBookPro15,4
- Mac-226CB3C6A851A671 = MacBookAir8,2
Normally when you do a Google search on a board ID you will find a hit somewhere. In this case nothing…
Ace in the hole GeekBench.com
GeekBench.com is one of the most well known benchmarking sites around. When you run a benchmark with GeekBench it will put the results in a searchable database.
Bingo, someone inside Apple ran this test or someone got an early review unit. Either way we know know what board ID Mac-53FDB3D8DB8CA971 is, a new 13″ MacBook Pro! Also notice the new iBridge/BridgeOS 16.16.5601.0.0,0. The Benchmark was only ran 6 days ago!
What is Mac-226CB3C6A851A671?
UPDATE: Found! MacBookAir8,2
Not totally sure yet, the best guess right now would be the updated 2019 MacBook Air. I will have to wait to confirm, when I find out I will update this post.
Found it!
You can only download and install 10.14.5 (18F2058) on the newly released hardware.
As usually with forked builds you can only install this BuildVersion on the newly released hardware. You will also only be able to download this version using the Mac App Store or instalinstallmacos.py on said new hardware. Trying to download this from the Mac App Store on older hardware will get you the old 18F132 or 18F203. If you try to download (18F2058) using installinstallmacos.py using older hardware you will get Installer: Error – ERROR_90F0494CE3 Product installation failed or one of the very similar number errors.
This version is only recommended for the new hardware.
If you do get a hold of this version it DOES look to install to all compatible Mojave systems. The reason behind this is all the current Board ID’s are listed in the Distribution File. You can read more about this here when this happened with the 15″ MacBook Pro Supplemental Update.
