Symptoms
- You have an Entire Mac backup created on macOS 13 Ventura
- You start full system recovery from this backup
- After recovery is complete, you're prompted to install macOS 12 Monterey
- Mac is unbootable after installing macOS 12 Monterey
Cause
System won't boot when the backed up macOS is newer than the one installed after restore.
Solution
Download the macOS Ventura installer manually using one of the below methods and run the recovery once again:
In macOS:
- Launch Terminal.app and execute the following command to download and install the OS installer into the Applications folder:
softwareupdate -d --fetch-full-installer --full-installer-version "13.0"
- Find "Install macOS Ventura.app" in the Applications folder and drag it to the data volume of your bootable media ("/Volumes/Data" is created on the external drive where the bootable media resides).
- Once you have macOS Ventura installer downloaded and put in the correct folder, run the recovery once again.
In bootable media:
- Launch Terminal.app (menu bar -> Utilities -> Terminal)
- Download the macOS installer package to the data volume of your bootable media with the following command, where "/Volumes/Data" is the mount point of the data volume (a volume on the external drive where the bootable media resides):
curl "https://swcdn.apple.com/content/downloads/25/16/012-92138-A_KGGGN26YQB/d0kr042ixfvkboeft8qt2i3aclr5bx1e6p/InstallAssistant.pkg" -o /Volumes/Data/macOS.pkg
- Unpack the macOS installer package with the following commands:
-
installer -pkg "/Volumes/Data/macOS.pkg" -target "/Volumes/Data/" mv "/Volumes/Data/Applications/Install macOS Ventura.app" "/Volumes/Data"
- Once you have macOS Ventura installer downloaded and put in the correct folder, run the recovery once again.
