Apple continues to make behind-the-scenes improvements to OS X that will allow future Macs with high-resolution Retina displays to show higher quality images



From Apple Insider:

Hidden within the OS X 10.7.4 update issued on Wednesday is a Retina-display-caliber icon for Apple's built-in TextEdit application. In OS X 10.7.3, the highest-quality version of the application's icon was 512-by-512 pixels, but after updating to 10.7.4, its resolution has been doubled.

With the quality of the TextEdit icon increased greatly to 1,024-by-1,024 pixels, the file size of the icon also grew from just 209 kilobytes in OS X 10.7.3 to 1.7 megabytes in 10.7.4.
