Mac OS X apparently supports SACKs, making Reno obsolete...

net.inet.tcp.sack: 1

vs

net.inet.tcp.newreno: 0

(from sysctl net | grep net.inet.tcp)

More here.

If it is congestion control implementation you need to identify,
it might be easier to you can also look at the TCP packet stream from the machine.
Here is a StackOverflow question on how to 'fingerprint' TCP Congestion control algorithm.
