So, the Apple changed the default resolution on both the 13 and 15" models. I'm not sure about the 13", but on 15" it's "Looks like 1680x1050", and it used to be "Looks like 1440x900". I'm curious why the change. As you know, it used to say "Using a scaled resolution may affect performance" (although, I never noticed any change in performance on my Retina Macs) So: 1. Maybe Apple thinks the new GPUs are not affected by this change performance-wise 2. Maybe it's just a trick to make the displays seem higher res than before 3. Maybe there is some technical reason that the displays are now default at higher res Anyone has any ideas?
