Can anyone see any difference between the iMac and the iMac Retina graphics?!
I loaded them both into Sketch and gave the Retina one "Difference" blending, which showed this.
Cropping to the Apple logo, with the non-Retina on the left and the Retina on the right, it seems there are slight differences.
I had to scale the non-Retina vector by 200% to match the size of the Retina vector, so perhaps that's having some effect.
It's great to see Facebook releasing these types of resources. Would be cool if others did the same(eg. Pinterest, Twitter, etc)
