Why do I have two recovery environments?

On my 16” 2021 M1 Pro MacBook Pro running Sequoia:

  1. Power off laptop
  2. Press and hold power button until you get into the recovery env.
  3. Notate the version of Recovery you’re in as well as the version of OS it says it’ll reinstall.

Now, power off again, but this time press and release the power button quickly and THEN press and hold it until the recovery environment comes up - notate the Recovery version as well as the OS it says it’ll reinstall.


On my machine, these are two different environments and offer to install two different version of macOS. I cannot find this documented anywhere. Can anyone else reproduce this?


The image showing Sonoma and Recovery Version 1.0 (505.100.1) is when I press and release the power button and then immediately pressing and holding.


The image showing Sequoia and Recovery Version 1.0 (509) is when pressing and holding the power button without a press and release before hand.

One is Sequoia, the other is Sonoma.

Sonoma is older than Sequoia, says the Mac was released when Sonoma was the operating system.


In Intel Mac days the older OS recovery environment would show if the recovery environment of the current OS was wiped, or became unbootable, and would usually be preceeded by a spinning globe as it downloads the older recovery environment from Apple's internet servers. I suspect Apple Silicon operates the same way.


The older OS would usually only show when you pressed command-option-shift-R on Intel Macs, where command-R would load the current OS installed recovery environment. It would appear you tapped into the same type of two versions on Apple Silicon
