Aloha everyone, I work in an office filled with Windows sheeple, and was recently showing some of them my newly-purchased 15" rMBP. One of them was looking at the display, wondering about the "retina" labeling and all and asked me the value of the max resolution. I checked System Information, and it indicated that 2880x1800 was what I was currently running (the More Space option on the Scaled section of Display Preferences). However, I took a screen shot that indicated I am actually running 3840x2400, double the resolution of the 17" MBP it replaced Anyway, I was wondering why Apple would indicate a lower resolution than what my rMBP was actually running? Has anyone else experienced this strange behavior? I've attached a couple of screenshots showing my discovery. I verified the resolution with the background I made in Photoshop. I trust Photoshop with accurate dimensions and it fits perfectly.
