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.
