May cast doubt on Retina Display Macs
The fourth OS X 10.7.3 beta has dropped a reference to an ultra-high resolution mode known as HiDPI, notes MacRumors. In some past betas of the update, opening the Get Info window for an app would present an "Open in HIDPI mode" checkbox, even though toggling it had no effect. That checkbox yesterday went missing, according to a new report.
Apple is rumored to be working on a new MacBook Pro with a 2880x1880 display, bringing the sharpness of Mac graphics into line with the Retina Displays on the iPhone and the iPod touch. Removing the HiDPI checkbox from Lion could signify that Apple isn't ready to build such a high-resolution computer. At the same time, however, the company will sometimes flip code on and off during a feature's development.
