MACOS 10.13 HIGH SIERRA USB INSTALLER INSTALL
Any ideas why this would be, and why it's not letting me install macOS High Sierra 10.13?Īlthough 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. With your USB drive connected to your Mac, launch the Disk Utility app. The process of creating the USB installer deletes all data on the USB drive, so make sure it doesn’t contain any important files. I then restart the computer holding the Option key and booted using the USB installer.Īfter a loading screen, I keep getting a Install macOS Mojave menu. To create a macOS Sierra USB installer, you’ll need a USB 2.0 or USB 3.0 drive with a capacity of at least 8GB.

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. But for some reason when I do this it keeps loading macOS Mojave 10.14. 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).

Select the High Sierra installer at this screen. Immediately on reboot, start holding down the OPTION (ALT) key to load the boot menu. If you wish to continue type (Y) then press return: Y With the newly created macOS High Sierra USB installer drive connected to the Mac, reboot the computer.

This means you actually need a Mac or a MacBook to create this bootable ISO. To abide with Apple’s terms of use, you must go through official channels to obtain the macOS installer. This guide will also be useful for those who can run Virtual Machines of macOS in environments like VirtualBox etc. As an owner of a MacBook Pro, it’s slightly unsettling that I wouldn’t necessarily be able to plug in a bootable USB or insert a DVD with the macOS installer image in the event that I needed to re-install my OS because my SSD ate the dust, or something. OS X was a different story, but also you had to pay for those versions. Normally you can’t obtain bootable media of macOS.
