I'm glad you cannot be killed by regret. Bought a brand new M5 Macbook Pro and for the third time I really tried to use Tahoe. Gave up. Erased everything and voilà, you cannot clean install anything but Tahoe. Thanks, Apple. Really silly, but I guess stupidity is on me for not asking first at the Apple Store. Should have sticked with a basic M4 Pro. Man, this is really, really silly.
