Sierra blocks disabling of unwanted processes

[Jim Smith]

Having finally updated to Sierra, I can no longer disable a number of processes that needlessly clutter the system when playing music files - such as Disabling Virtual Memory Swapping, etc.  I have always used Maintain's Cocktail program (for Apple) to disable unwanted processes, getting the count down to around 60 or so, with well over 98% of the system free.  Not even close to that with Sierra...

 

This is on my MBP, which is ONLY used to play music files.  The music files are used for RoomPlay system/room voicing sessions.

 

There may be a path to overcome this blocking - which is called System Integrity Protection.

 

Has anyone used this technique to overcome the blocking and liked the results?

I turn it  (SIP) off on all my machines (for other reasons).  Nothing bad ever happened.

WOW!  Thanks!!!

Why is this important? When my Macs aren't doing anything CPU-intensive, they don't use much CPU. Even now, listening to music with iTunes, it's 95-97% idle. And even if it wasn't, do you really think that will affect your music?

Although I agree with Kirk, and in addition I can max out all of my processors compiling something in parallel when listening to music, and never hear even a hint of sonic degradation, I think it is important that people be allowed full access to do whatever they want with their computer.

 

Apple has decided to take a number of steps to protect the "integrity" of the operating system (which can easily be reinstalled, in case of a catastrophe) by locking it down and protecting it from its owner.  I even had them refuse to do a warranty repair once because I put third-party memory in, rather than their over-priced, rebranded but otherwise identical part. Now they solder it in. Another time they told me installing Fink and X11 apps had damaged my hard drive. Things aren't heading in an open direction.

SIP is a security feature. It prevents apps from installing malicious software in the system space. And I think it's a good idea that it's not easy to turn it off, because people may be tempted to deactivate it to hack with something, then forget to turn it back on. 

 

You can always run Linux if you want to do whatever you want with your computer. :-)

Or you can turn off SIP in two minutes.

 

I've "forgotten" to turn it back on for years.

It is easily audible (200+ processes running & 97% idle) compared to 64 processes running and the MBP at over 99% idle (includes Audirvana controlling some processes as well).

 

At least it is on my system - maybe my MBP is different.
