in the meantime I have found this about Mavericks and 10-bit color depth:
"10-bit video displays: Photoshop users and other graphics professionals have wanted proper support for 10-bits-per-channel video displays on Macs. (This isn’t about the file format, but the data path to the video monitor. Most displays support 8 bits per channel of color, but some high-end monitors support 10 bits per channel for smoother gradations and better color accuracy.) To support 10-bit video requires an unbroken chain of components: The monitor, the graphics card, the cable, the application, and the operating system and its graphics driver software. If any part of the chain doesn’t support 10-bit video, it won’t work. And it might not work on the Mac any time soon, due to Apple’s continuing lack of 10-bit video APIs in OS X. The displays are ready, the graphics cards are ready, compatible DisplayPort cables are ready, Photoshop is ready…OS X remains the one broken link in the chain and there is no sign that this has changed in Mavericks."

amongst others: several people have -not simple- problems with Adobe products after Maverick update.
Could at be, that a 3.000 $ or more $ workstation user has no possibility to work with images in 10-bit mode with Apple products? And you cannot change the graphic cards in it, but I think the cards are not the problem. I think it is a good idea to spent only 1 million $ of the more than 100 billion $ (100.000.000.000) cash reserves that Apple Inc. has to solve this little problem.
For this amount I will write a driver for this.
Its up to you, Timi.
