I'm glad it is working well for you and many others. But those of us that rely on our Mac's production to pay the bills need to take a more cautious approach, which is exactly what I'm doing after High Sierra cost me a lot of lost production time last year.
I'm just a casual user, pay bills, read news, stream, etc., and I won't touch any Apple OS upgrade for at least 2 patches. Now, this thing is going back to beta? I'm scared to touch it until I see problem free operations, or, "It just works".
