If you're copying code into a Keynote presentation, you can use Pygments' RTF output mode, copy it to the clipboard, and just paste it into a text box in Keynote. That way, because it's actual text, it's smooth regardless of output resolution. Here's an example I just pulled from my shell history: pygmentize -f rtf -O "fontface=Fira Code,fontsize=26" -l prolog familyinteract.pl | pbcopy (That was for pasting code into Pages; for Keynote you'll probably want a bigger font size.)
