Reformatting MacBook Pro but need to revert back to the original OS it was shipped with
Hi, I’m using a 16-inch MacBook Pro M1 (2021). It was originally shipped with MacOS Monterey, and I had updated to Ventura later on. I have not updated it to Sonoma as of now as some apps that I’m primarily using are not yet optimised with it. I’m in the need for formatting and completely erasing my MacBook and now that macOS Sonoma is out, I’d like to know if after the reformatting process is done, would it automatically be rebooted with Sonoma installed, or Ventura 13.5.1 (which is the current version installed), or with the OS it was original shipped with (macOS Monterey). Thank you.
MacBook Pro 16″, macOS 13.6
