Mac App Store Now Requires 1024x1024 App Icons
Apple has updated its Mac App Store to refuse app submissions without an icon that is at least 1024x1024 pixels in size, reports TUAW.
Developer Daniel Jalkut notes that the latest requirements for the Mac App Store include an app icon that's at least 1024x1024 pixels, which is extraordinarily huge. To put that in perspective, each and every submission to the Mac App Store going forward needs to include an icon that's bigger than my MacBook's display (1280x800), and bigger even than a standard resolution iPhone or iPad screen. That's a big icon for sure.
The larger icon is necessary for the new Retina Display MacBook Pro.
