I like these, but they seem a bit fuzzy to my non retina macbook display. Particularly the music and calendar app icons just seem overly aliased. Can anyone else confirm?
Did you actually install them? I don't have a mac at work to try them out on, but when I downloaded the zip file it contained large crisp pngs. Maybe they just look fuzzy in the web page preview?
The preview looks fuzzy, because they look like they have a slightly lighter outline, which is some way to do anti-aliasing. The PNGs in the download archive don't have these outlines.
