Sort of, but be warned it wont automatically revert a time machine backup of your Tahoe files to a Sequoia system, you have to manually copy them. Similarly you have to recovery boot into disk utility to flatten your hard drive before installing Sequoia from (say) a memory stick.
It all seems a bit needlessly tricky. Frankly though - for me at least - it's worth the trouble.
I've just gone through the rather painful and protracted process of reverting from Tahoe to Sequoia.'Reverting' rather than 'downgrading' since Tahoe is in no sense an upgrade.
I consider myself quite tolerant of UX quirks, iPhones are still pleasant to use, particularly if you select 'reduce motion' from the accessibility settings.
Tahoe though, bugs aside, is just genuinely unpleasant to use and interact with. By far the most offensive thing to me is the pointless rounded rectangle thing. It delivers absolutely no value at all to the user and defies any form of justification. How in any form is this a decision designed to improve things for the user?
The other multiple weirdnesses commented on elsewhere while unpleasant are more liveable with, but I honestly never found a single change that improved my interactions with the computer. How on earth can you have spent a whole year on this and why didn't anyone have the authority to pull the plug?
I would no longer recommend a new mac to my anyone. A second hand model running a previous operating system makes far more sense.
I used to live just down the road from Fred Dibnah's house when I was in my early 20's. It was quite an interesting old building with a fairly steeply sloping garden that led down to an old workshop packed with steam engines and similar mechanical bric a brac. Despite the layout you could easily see down to the bottom of the garden from the pavement as you passed by.
I had a sort of standing joke where I would wind my girlfriend up by pointing out that it was Fred Dibnah's place every time we walked past. I did this perhaps a little too often.
One day, she had had enough and told me in a very loud voice that 'she couldn't give a shit if it was Fred Dibnah's house'. That's when I saw his startled face peering up from behind a traction engine. Sorry Fred. I hope you can forgive me from that big old chimney in the sky.
