Since macs rely mostly on the 'command'/'apple' key for that stuff (instead of Ctrl), on OSX Select All is just cmd+a, like how Copy/Paste are cmd+c/cmd+v respectively, so it doesn't interfere. And on Emacs you start getting into multi-key combo finger dances for that (e.g. "Ctrl+x h" = highlight all), which OSX doesn't emulate for various reasons I'm sure...
