There have been tons of reports and evidence that has suggested that Apple is looking to upgrade OS X to support ultra high resolution “HiDPI” screens. The evidence so far has been in the form of icons which Apple has been updating slowly to higher resolution copies, and thanks to the latest OS X 10.7.4 update, it seems that more proof of Apple’s HiDPI move has been uncovered. A couple of icons are proof of that and one of them is the TextEdit app whose icons now come in ten different sizes: 16×16, 32×32 HiDPI, 32×32, 64×64 HiDPI, 128×128, 256×256 HiDPI, 256×256, 512×512 HiDPI, 512×512, and 1024×1024 HiDPI. The Automator app has also received the same treatment but has also been given a makeover as pictured in comparison picture above. While Apple has not officially confirmed anything yet, this seems to corroborate rumors that have suggested that Apple could be launching a Retina display 15” MacBook Pro in the near future whose resolution will be 2880×1800, double that of the current resolution of 1440×900. So, what do you guys think? Would a Retina display MacBook Pro be of great interest to you?
