Finder is fucking dire. I spend more time on the terminal.
The vertical column mode is useless as file names are always too long. It forces you to drag and drop and open loads of windows rather than cut and paste via menus. Open vs rename is fucked up. Half the machine is hidden initially. Hiding file extensions is just broken. Every view seems to forget what state it’s in. The file copying and continue copying thing fucks up network drives. cp is actually an order of magnitude faster. The icons at the top are shit. All the keyboard shortcuts require mutant hands that only emacs users have. The trash can semantics of “put back” are just crap. It crashes at least once a day for me. I could go on for days.
Windows 10 is notably better.
