This appears to be a two part problem. I too could not send midi sysex's using a mid-2011 OSX 10.7.5 equipped iMac. I did find a workaround - first, I had to use the mmj jar and jnilib's and secondly I had to tell my code to use timestamps of -1 and NOT to use system.currentTimeMillis(). In my case I'm sending realtime sysex messages, thus a timestamp of -1 works for me. I don't know what timestamp to use if you're dealing with midi note on/off's etc. Perhaps the timestamp is milliseconds into the future? I don't know. But I do know that I had to use both mmj and take better control of my timestamps. After that, things work as expected.
