For the people doing a clean install how are you doing it? I don't have a USB drive at hand, so I factory reset and formatted drive and as soon as I logged into Sonoma on first boot, immediately updated to Sequoia. Which took ages as well but that's the closest one could get without a USB drive I guess

erase all content and settings method

no need to erase the hard drive or usb

only takes a few minutes and good as new!

Since I saw there was a Data partition I thought it wasn't a full clean install when I tried it. But yeah, if you do format the drive then it will pull from the recovery which is always Sonoma.

So I take it, if you don't format the drive and do that method it's essentially a clean install, absolutely no settings / preferences / leftover crap?

Since I upgraded the Keychain Access broke, I rebooted my Intel MacBook Pro T2, selected CMD+R, Erase the disk, and reinstalled macOS Sequoia. It has some bugs, for example, if I change the Apple Account avatar doesn’t change my Avatar admin account and, without understanding why, the Avatar of my admin account changed the avatar without doing nothing! tvOS 18 also maintain the old Memoji when I use other on my iOS18 and macOS Sequoia!

Oh wow that's effed up! After erasing the disk and mac activating finished, I could only choose to install Sonoma, cause the recovery partition only contains Sonoma. Curious how it showed Sequoia for you

Yes. It’s the recommended way of returning Mac to factory state before giving away or selling. It leaves only the immutable Signed Sealed System volume in place. Machine will start up in Setup Assistant for new owner as a factory new machine would.

Option-Command-R: When you press and hold these three keys at startup, Recovery might offer the latest macOS that is compatible with your Intel Mac.

With me, after upgrade to macOS Sequoia, CMD+R allows me to Reinstall macOS Sequoia.
