Ever since installing 10.12.1, I've been having a bunch of processes randomly entering a quasi-paused SIGSTOP-ish state (neither closable, apps not "bouncing" (loading) and just not responding. Running Instruments, correlating logs and such doesn't identify any clear cause. I'm having to `sudo kill -CONT -1` in order to get things moving again. I'm wondering if it's related to XNU mitigations or just some spurious "system configuration entropy" on my box.

I'm still with 10.11. I don't plan to update soon, since the benefit of Siri, Photos and the other major features is quite small, compared to the risk that I might loose working days if something goes wrong ( I'm a freelancer ).

As far as I read in the article there will be 10.12.1 ( the final fix ) which will have that part of the kernel refactored. I hope Apple will also support 10.11 and issue an update with the same fix.
