There is a known issue with Mavericks and LR vs PS since most of a year, now:
It is apparently an issue with Apple color-management that Apple has programmed around in their applications while Adobe has not, but perhaps Adobe is waiting for Apple to fix something instead of programming a workaround.
this is just a shot in the dark and since there is a problem/issue that folks are already aware of what i have to suggest may make no sense ...
what about calibrating your monitor in some way ... ?? does this have anything to do with anything? just an idea ... though it may not be logical there ya have it
I have my monitor color calibrated with a color munki. Are you suggesting
removing the profile?
