A small number of well-considered UI/UX design schemas really is a useful thing. Apple is, generally, good in many particulars. It is extremely conservative, with only two desktop models (Classic Mac, 1984 - 2000, OS X, 2001 - 2019, and ongoing, which is to say, longer than the original interface). It is ultimately completely antithetical to how I work in desktop, and I find myself vastly prefering Linux and the opti…
The design and usability history of OS X is actually a bit more diverse. The first iterations ("lickable" Aqua) had serious issues, favoring buyability and wow-effects over everyday usability. (E.g., as Doc icons increased in shape on pointer proximity, they also dodged the pointer as the intended drop target in default settings.) This consolidated with 10.3 and 10.4 was the first real usable version of OS X, leading…
My preferred desktop, Windowmaker, is even more conservative, as it's seeking to emulate the 1980s NextStep desktop, though there have been a few changes, and I noticed many of them sharply.
