This is obviously tedious and really hard to automate. However, you need to create a new admin account on the disk before you can do that… Avoiding the Downgrade Then you can quit Disk Utility and start the Mojave installation process.Īfter completing the installation, you want to remember to return to Recovery and re-disable external boot again. You may have to choose ‘Show All Devices’ from the View menu to be able to select the internal drive with all sub volumes, not just the system or data volume. In Disk Utility, erase the entire internal drive. Once booted to the Mojave installation drive, start Disk Utility. Now, reboot the Mac and hold the option key, from the list of devices to boot from, select the Mojave Installer drive. You could also disable ‘Secure Boot’ entirely, but that is not recommended as it will, well, disable all system security verifications. This network connection is required to verify the integrity of the system on the USB Installer drive. You will definitely need the servers listed under ‘Device Setup’ from that list and many of the others, depending on your deployment workflow. You can see which services and servers the network needs to be able to access in this kbase article. You also need to connect the Mac to a network with non-filtered/proxied access to Apple’s servers, either with Wifi or an ethernet adaptor. Instead, you have to boot to the pre-installed Catalina, work your way through the Setup Assistant, and create a local administrator user before you can boot to Recovery to change this setting. When you get a new Mac “out of the box,” you cannot directly boot to Recovery to change this.

This utility is protected and requires the password of a local administrator user to access. To boot a new Mac with a T2 chip off an external drive, you need to allow external boot from the Security Utility in the Recovery partition.
This will delete the target volume data on the USB disk. > createinstallmedia -volume /Volumes/Untitled -downloadassets You probably want to add the -downloadassets option to add the current firmware to the USB drive as well.

Then you can use the createinstallmedia command in the Install macOS application to build an external Installer Drive on a USB drive. If you are running Catalina, you can also use the new option in softwareupdate : > softwareupdate -fetch-full-installer -full-installer-version 10.14.6 You can do so from by following this App Store link.

First download the latest Mojave installer. The solution requires a Mojave Installer USB disk. However, if a Mac was shipped with Catalina pre-installed, it will boot to Catalina Internet Recovery, regardless of whether the Mac can boot to Mojave or not. This used to boot to a Mojave (more specfically, the system the Mac shipped with) recovery system, and then you can wipe and re-install Mojave.
So far, the recommendation has been to boot to Internet Recovery with the shift-command-R key combination at boot. Apple is likely not very motivated to fix this.
The reason seems to be that the Mojave Installer application chokes on some aspect of Catalina APFS. Attempts to run the Mojave installer from a Catalina Recovery (local or Internet) will also fail. These ‘solutions’ are not supportable on scale.)ĭirectly downgrading from Catalina to Mojave with the startosinstall -eraseinstall command will fail. I am aware that someone might be able to hack together a Chimera Mojave with Catalina drivers. Any new Mac models that Apple introduces from now on, will also require Catalina and cannot be downgraded to Mojave.

You cannot use these instructions to force a Mac Pro or MacBook Pro 16” to boot to Mojave. The exceptions are the iMac Pro (High Sierra) and the MacBook Pro 16“ and the Mac Pro (2019) which both require Catalina. As of this writing, all new Macs require at least Mojave. Usually a Mac requires at least the version of macOS that the model shipped with when it was introduced.

Important Notice: these instructions will only work for Mac models that can boot to Mojave. If your organization has blockers for Catalina (incompatible software, etc.) you may want to install Mojave on these Macs. Apple has started shipping Mac models that used to come with Mojave pre-installed with Catalina.
