me suspects the recent update from apple.
I guess I will go fetch an old pc with CS5 suite and xp .
meanwhile, I will try the things suggested here lately, like unhiding the library, http://www.luminous-landscape.com/forum/index.php?topic=63038.0
or like uninstall and removing all printers from from printer list and re-installing (and the cups issue)
here about the unhiding http://www.drycreekphoto.com/icc/mac_osx_sys_profile_folder.html
found here on this forum
Updated: Solved somehow, prints perfectly now
Tried unhiding, and a test print of the AdobeRGB pixl test image, from Photoshop, and it prints perfect from at least macbook air.
I will try doing that to the other mac. But I happened to dump some standard icc profiles into the library first too but that should not matter I think. From http://sites.google.com/site/chromasoft/icmprofiles
Also, the black and white dialogue works fine, with the new drivers for mac, (from Epson UK) both in Lightroom and in Photoshop, just that one has to choose Printer manages colours first. In LR it is hidden to the right. In PS one also has to choose it to the right first, then it is possible afterwards to go to the black and white menu.
