2018 MBP refusing to update 10.13.6

Here’s an unusual problem I am currently encountering.. any help is appreciated!


A good friend bought a 2017 mackbook pro in june. It was updated to 10.13.5. She exchanged it to a 2018 macbook pro a couple weeks ago (in july) and restored her system from a time machine backup she had made on the 2017 machine.


Now when she goes and tries to update to 10.13.6, the app store wont execute the update. It downloads it and tells you the computer will need to restart, as normal, but when you go about clicking "restart" a prompt pops up saying the update files have been "modified", whatever that means, and nothing happens. When you try again you are stuck in the same "loop"...


She even tried direct-downloading the combo update as instructed in this thread (https://discussions.apple.com/thread/8482215), but when trying to run the .pkg a prompt pops up saying this file type isnt supported by the system..??


Obviously a complete restore is not an option right now.


Help!

What's her secret?

Can she install a fresh OS, update it first, then restore backup? (nvm)

She bought the 2017mbp within 1 month of the 2018’s being released, so she was granted an exchange!

The solution you’re suggesting might have to be an absolute last resort as its quite a hassle for performing a simple os update. I hope someone has a simpler solution..!
 
Typically, when new Macs are introduced, they initially have a special OS build. Then, when subsequent OS versions or updates are issued, that Mac can use a regular OS build.

Open the "System Information" app. On the left side, click on "Software" and look on the right side for "System Version:". If it says "macOS 10.13.5" and the number of in the parentheses starts with "17F", then you are indeed running High Sierra 10.13.5 and this would be a big bug as the system should not have allowed that on the 2018 MBP. You should call Apple to try to resolve the issue. Also please report back that this actually happened so we know that this problem exists.

If instead, you have macOS 10.13.6 with a build number (in the parentheses) of "17G2112", then you have the special OS build. (This build number comes from everymac.com.)

You cannot (hopefully) and in any case should not apply the regular High Sierra 10.13.6 update as again, at present, the 2018 MBP requires a special OS build and 10.13.6 pre-dates the introduction of the 2018 MBP.

There is "macOS High Sierra 10.13.6 Supplemental Update for MacBook Pro (2018)" available.

Why don’t people trust the check for updates and trust Apple knows more about their product than you? T2 chip and other changes most likely why software isn’t correct for the 2018.

Huh this is interesting, I will report back as soon as I have this info. I was positive that 10.13.6 was the throttling bug update, but now you have me doubting what version is actually running on her machine.

The update i’m reffering to shows up in the "check for updates" section of the app store...

After further verification, the machine is running the 17G build, but still will not accept the supplemental update. See attached link:

How can I go about installing that update?
