Using Shark to profile an iPhone game, pressing "Start" doesn't do anything

Question

I've done a decent amount of reading about how to profile iPod applications using Shark, and all works well until I try to click "Start" (and nothing happens). I've tried profiling an individual process (app), all processes, and it doesn't seem to Start. This tutorial is one place that I used to set it up (so I think I'm following all the steps):

(I've also rebooted my mac and iPod)

Anyone have any ideas on what to try next?

Answer 1

Have you tried the Time Profiler instrument? Apple seems to be moving in that direction.

Answer 2

Shark support has been dropped on iOS 4. Official Apple position can be seen here:

They expect you to use Instruments and Time Profiler instead.
