I was doing some work on my Python bindings for libusdt which reminded me about how annoying it is when DTrace isn't working.
The solution (as I noted here) is pretty simple:
- How to run and use the Trace Route on Mac OS? Trace Route is a utility that records and displays the route through the Internet from your computer to a specified destination computer or server. It also counts and reveals the amount of time spent during each 'hop' (the route taken by a data packet from one node to another in the network).
- Dtrace is included by default with Solaris, Mac OS X and FreeBSD. There is an equivalent for Linux, Strace, but it is not as great for troubleshooting production environments. El Capitan by default enables System Integrity Protection, which significantly limits DTrace capability on your Mac. Read more on this and how to disable SIP here.
- Reboot into Recovery Mode (hold down ⌘R during boot)
- Launch a shell and run
csrutil enable --without dtrace - Reboot and allow machine to boot normally
Embarrassing story time:
This is neatly documented by Brian Bennett in a StackExchange post (from 2015!). Not only that, but I even left myself a breadcrumb linking to that StackExchange post in May of 2016. But sadly none of that stopped me from taking to Twitter to ask how to solve this problem.
This “traces” disk I/O execution live. Each time a disk I/O completes, a line of output is. Archive for the ‘Mac OS X’ Category ZFS: Apple’s New Filesystem That Wasn’t. Prologue (2006) I attended my first WWDC in 2006 to participate in Apple’s launch of their DTrace port to the next version of Mac OS X (Leopard). Apple completed all but the fiddliest finishing touches without help from the DTrace team.

Oh well. At least now I can successfully run the test suites for libusdt and my Python wrappers for it locally on my laptop.
How to run and use the Trace Route on Mac OS?
Trace Route is a utility that records and displays the route through the Internet from your computer to a specified destination computer or server. It also counts and reveals the amount of time spent during each 'hop' (the route taken by a data packet from one node to another in the network). Trace route is useful when you are trying to diagnose the reasons why certain websites load slowly.
This utility sends a packet to a declared computer or server to count: 1) The number of hops, and; 2) The time spent during each hop. Furthermore, Trace Route attempts to resolve some basic issues with the route to a specified computer or server (this is sometimes not possible due to a device's firewall).

Perform Trace Route utility via Network Utility
You can use the Trace Route utility, which is included in the Network Utility feature of the Mac OS. Access Network Utility using Spotlight - press Command and Spacebar in a new window, type Network Utility, and press Return.

Alternatively, you can enter manually through the Applications folder under CoreServices. Open Finder, from the finder menu at the top of the screen choose Go, and then select Go to folder. Type the route: '/system/library/coreservices/applications/' and launch Network Utility.
Once Network Utility is launched, select the Traceroute tab and enter the domain name or IP (Internet Protocol) address of the preferred computer. Click Trace and wait. This may take a few minutes.
Use terminal to perform trace route
Launch Terminal from the Utilities folder under Applications. Alternatively, you can use Spotlight by pressing Command and Spacebar, type Terminal, and press Return. Once Terminal is launched, type the command 'traceroute' and after a space, type a domain or IP address of the preferred server or computer, and then press Return.
