Then you can use a more normal launch method, for example open .../Minefiled.app . ./cold.sh firefox-bin startup.d stop-main.d dtrace -Zqw -x dynvarsize=64m -x evaltime=exec -p 35209 -s sigcont.d -s startup.d -s stop-main.d kill -CONT 35209 Total: 2000.401494ms Note that stop-main.d does not work without $target, even though main-entry is a USDT probe. mozilla*:::main-entry ? I am not very familiar with creating USDT probes. This might help if you haven't seen it: <http://blogs.sun.com/dap/entry/writing_a_dtrace_usdt_provider

This could just be an issue of making sure that dtrace has learned about your provider by the time it parses the probe definition. This email sent to site_archiver@lists.apple.com
