How to fix slow OSX emoji palette

I fixed my FontBook got very slow. Whenever I opened my palette, it took around 10 seconds to show up.

Notice if you do this, extra fonts you installed will be deleted. So better to backup your fonts first.

  • Open Font book app which should be under /Applications folder.
  • Click Restore Standard Fonts... under File menu.

Font Book

Then no more waiting time to open Emoji & Symbol palette :)
