I've got a 2018 MacBook Pro (Model ID : MacBook 15,1) that shipped with macOS Mojave 10.14, that I need to downgrade to run macOS High Sierra 10.13.

I've tried reformatting the main drive using Disk Utility and then re-installing the OS from recovery mode, which from past experience loads the lowest OS the machine shipped with (for the 2018 MBP that is 10.13.6). But for some reason when I do this it keeps loading macOS Mojave 10.14.

So I've gone for another solution: I've created a USB installer of macOS High Sierra 10.13, wiped the MacBook Pro drive again, gone to the Startup Security Utility, and set medium security and allowed boot from external drive. I then restart the computer holding the Option key and booted using the USB installer.

After a loading screen, I keep getting a Install macOS Mojave menu. Any ideas why this would be, and why it's not letting me install macOS High Sierra 10.13?

Although the 2018 MacBook Pro originally shipped with macOS High Sierra 10.13, could it be that I have a later model of 2018 MacBook Pro, that only has drivers for macOS Mojave 10.14 and later? Or do all 2018 MacBook Pros work with the same drivers?

  Have you have downloaded the macOS High Sierra 10.13.6 installer (the one currently available on the Mac App Store), before creating the USB installer. Make sure you are not using an older release of macOS High Sierra.

  @NimeshNeema i downloaded High Sierra from the mac app store, (from a machine which is already running 10.13) and noticed that the install file was only c. 20mb. For comparison the Mojave installer is c. 6gb. When i tried to create a USB installer using the guide as set out on Apple's website, i got the following error in terminal : /Applications/Install macOS High Sierra.app does not appear to be a valid OS installer application. - presume this is related to the installer being "wrong" which is also indicated by its file size.. any ideas ?

As described in this support article, there are different ways to load macOS Recovery:

• 
  cmd+R: Install the latest macOS that was installed on your Mac.


• 
  alt+cmd+R: Upgrade to the latest macOS compatible with your Mac.


• 
  shift+alt+cmd+R: Install the macOS that came with your Mac, or the closest version still available.

I suggest you try the last option and see if it lets you install macOS 10.13.

It is possible but not all the time. Here's why:

1. Latest macOS might have features that won't run on the older Macs(hardware wise. eg: fingerprint reader on new MacBook but older macOS won't have support for that)


2. Drivers might be outdated


3. The bootloader and other parts of the hardware might outright restrict this due to security issues.

Is it possible to install an old version of Mac OS on a new Mac? will answer a lot of your questions.

Again, it's not impossible but you need to consider the above points.
