Is it worth reading the Mac HIG from the 2000s? YES!
Because current HIGs pruned all the historical context of desktop app design in general.
A lot of you aren’t reading it & it shows. I hate being so blunt but the further we go like this, the shittier our Mac apps are going to get.
When you never had a clue about specific patterns and paradigms of Mac-app design, you don’t notice it, and therefore you don’t implement it in your apps.
Only knowing bad app design leads to worse app design.
