Just noticed that the option to select clipboard for synchronization (#966) is only available for win32 clients, not OSX clients.
Wouldn't hurt to provide the option, when you get the chance (probably as an option with a sub menu, off the Features link of the xpra menu?).
See also r11015. To add support, the osx clipboard needs to extend the translated clipboard and we need a menu for it (or at least an initial packet to set the current remote clipboard).
Done in r12059, see ticket:966#comment:7.
Ok, this looks like it's working as 'expected'. (Seems like sync'ing the primary or secondary is making pasting locally copied content fail to paste into browsers, but sync'ing to the primary clipboard does allow copying from server xterms, which is handy).
Tested with 0.17.0 r12380 client against 0.17.0 r12380 fedora 23 server.
Closing (at last).
