However earlier today, Instapaper’s developer, Marco Arment, published on his blog that according to multiple sources, the next iMac refresh will not be seeing Retina display and will instead be making an appearance in the Fall of 2012. He states that production yield along with bandwidth constraints will make it difficult for Apple to introduce a Retina capable 27” iMac, at least not anytime soon. With the launch of OS X Mountain Lion expected to be in July, Apple could be looking at launching the new iMacs and Mac minis alongside the release of the operating system as well. Either way we will be keeping an eye out for the refresh, so be sure to check back with us in the future for more updates.
