Macs have numerous weird issues that seem to be beyond Apple to fix. My pet hate is that there's no easy way to just create a new file in Finder. On any sane operating system you'd just right-click and select "create new text file", etc and it'd create one. Macs give you nothing.

And that's before we get into WTF is going on when you hold shift and the cursor keys in a text editor. Sometimes it selects forwards like you want, but sometimes it inexplicably starts to select baskwards, selecting words and the entire paragraphs.

It's like certain key parts were written by someone having a bad day who just thought "this'll piss them off".
