![]() The benefit of this new method of installing major macOS upgrades is its efficiency and speed. If you had intended updating Monterey to 12.6.1, but clicked on the wrong choice and went for 13.0 instead, there was no way out: Software Update went ahead and dragged you screaming and kicking to Ventura instead. Instead of 13.0 being delivered as an upgrade installer app, it came as if it was just an update. If you were given the option by Software Update of updating Big Sur to 11.6.1 or upgrading to Monterey 12.0.1 and unintentionally clicked on the upgrade rather than the Big Sur security update, then the simple way out was to quit the Install macOS Monterey app and try again to get the security update.Īpple changed this with the release of Ventura on 24 October last year. When Software Update downloaded the upgrade to take your Mac from Big Sur to Monterey, you got an app Install macOS Monterey. ![]() This is even more complicated for Apple silicon Macs, whose firmware is different, and can’t be updated the way that EFI firmware has been in the past.īut for Big Sur and Monterey, upgrades from previous major versions of macOS were still performed by full installer apps. This is because of the boot volume group and the way that the Signed System Volume has to be constructed: that’s too big a job for an ordinary installer package, so even updates now come with their own installation tools built into a software update ‘brain’. Not only are there no standalone installers any more, but even minor updates are managed quite differently.
