&gt;<i>Unfortunately, it seems iotop and iosnoop are broken unless I press this big red button that only experts can press to disable SIP, when all I want to do is a little system profiling.</i><p>Wanting to do &quot;system profiling&quot; for your &quot;apps&quot; already makes you an expert compared to the  regular user.<p>And there&#x27;s nothing much complicated to disabling SIP, you can do it in 2 minutes with one reboot and a command line command.<p>If you know how to use iotop and iosnoop, you know how to do that.
