About Mac OS Tahoe:
“Tahoe is the worst user interface update in the history of the Mac. Every change is either wrongheaded, poorly executed, or both. The Mac remains usable only because of Tahoe’s lack of ambition: it mostly alters the appearance and metrics of interface elements rather than making fundamental changes to the structure of the Mac UI. Thank goodness for that. The bad ideas embodied in Tahoe reveal an Apple design team that has abandoned the most basic principles of human-computer interaction.” — John Siracusa
“Tahoe is the worst regression in the entire history of MacOS. There are many reasons to prefer MacOS to any of its competition, but the one that has been the most consistent since System 1 in 1984 is the superiority of its user interface. There is nothing about Tahoe’s new UI that is better than its predecessor…. Fundamental principles of computer-human interaction — principles that Apple itself forged over decades — have been completely ignored.” — John Gruber
I wonder if the UI changes in Tahoe can be directly traced to the rumor of a touchscreen Mac. I am not interested in a touchscreen Mac. I already have an iPad Pro with a keyboard. Looking at certain aspects of Tahoe, like the window borders, suggests that directive to the design team.
