Just figured out that you cant put #send on master, so the crash caused when in mixer you apply #send on master track from favorites dsp menu. Hope this helps.
In this scenario, putting #send device on master, crashes R3 instantly with no backup/crash log.
Check the link, there is an xrns file and applereport crash log file. Xrns file does not contain #send device on master, so its gonna be easy to reproduce this bug, just put #send device on master channel and R3 will crash.
My specs: macbook pro core i5, os x 10.9.4, r3.0 (32bit, no bridge/sandbox)
