Hi all, I've replaced my 13' mid-2010 MBP to 15' MBPr. I hook these MBPs to Dell 27' monitor @ 2560*1440 resolution. I have been using Parallels Desktop in Coherence Mode, albeit slowly, on my 2010 MBP, and it worked with no problem at all. Now I installed Parallels Desktop + windows 7 (same setting) and I got these problems: 1) "Enter Coherence mode" is not activated. 2) On full screen mode, windows does not present the right screen resolution, on both MBP's retina screen and 27' Dell's 2560*1440 3) Sync between Mac and Windows fails. Folders like Desktop, Downloads were automatically syncing previously but now I have to transfer the files manually. 2) looks like some driver sort of problem to me but for 1) + 3) Parallels is clearly failing on 'like a mac' feature. FYI I have tested VMWare on my new MBPr but it also fails to enter its own coherence mode.
