What congestion control algorithm is implemented in TCP in OSX 10.9? I would like to know if it uses NewReno, or something newer like Cubic in Linux.

In OSX Yosemite it appears to be CUBIC. In the sysctl -a
output I see
net.inet.tcp.newreno_sockets: 0
net.inet.tcp.cubic_sockets: 21
net.inet.tcp.use_newreno: 0
net.inet.tcp.cubic_tcp_friendliness: 0
net.inet.tcp.cubic_fast_convergence: 0
net.inet.tcp.cubic_use_minrtt: 0
