Apple approved the app update yesterday FolderWatch, which is designed for Mac. It is therefore an application available on Mac App Store. Interestingly, the application states in its description Retina Graphics. If you remember iTunes App Store during the time after the performance iPhone 4 s Retina display, similar labels were filled with it daily. If you are a fan of conspiracy theories, you will certainly have no problem imagining how the developers got it available early MacBookys HiDPI display.
However, if you are not a member of the X-Files team, you will be satisfied with the more likely solution, which is that the authors of the application improved its graphics. Moreover, if it were truly an application modified for HiDPI displays, the description would probably say Retina Display ready or HiDPI Display.
I have a layman's question, how long will I have to wait before I can have a display of the same quality as my iPhone 4s?
well, considering that iphone It has 326ppi, which means that the resolution of the iMac would have to be about 10 by 000 (just a very rough estimate) and that would be quite good for even 6 of today's top graphics cards, at least for another 000 years.
