25. Left-clicking in a window to raise it _sometimes_ performs actions in the app (e.g. clicking a button or scrolling the window) and _sometimes_ only raises the window. It seems to depend on the app.

26. No ability to use focus-follows-mouse.

27. Home/End keys send you to the top/bottom of the whole document instead of the start/end of a line. The latter is much more useful to me and I use it all the time. You can change this behavior with a terminal command followed by rebooting, but some programs still do whatever they want.

28. Automatic text replacements change the text you entered into the text that Apple thinks you mean. (Can also be disabled.)

29. Holding down an alphanumeric key brings up an accept/symbol selector, as on iPhone. This isn't compatible with many terminal applications like vim.

30. The dock has a tendency to move automatically to another display when there is a maximized window on that display. (I know how to move the dock by going bottom of the display and moving the mouse down, this isn't that.)

31. The camera notch can hide icons and you have no way to get to them without either connecting and external display or a workaround like https://github.com/dwarvesf/hidden.
