* Can't change SystemSounds Folder File Permissions!? *

Guys:

I'm trying to perform a chance to the insanely-grating, irritating file move ("Volume Mount.aif") sound in El Capitan that's been documented on these forums for previous OS X versions. It involves changing the .aif sound files in System\Library\Components\CoreAudio.components. At that point, one has to right-click, Show Package Contents, and then navigate to SharedSupport\SystemSounds\system.

It's in that bottom level folder that I have a problem. All of the sudden, since the update to El Capitan, my Mac refuses to let me paste files (in this case, a replacement for the VolumeMount.aif sound file).

Moreover, the Finder won't let me change the file permissions to add "write" to this folder, or even add Administrators to the permissions group.

I've unlocked the padlock icon to allow filer permissions changes, but any attempt to add a user or change the permissions of existing users in this folder results in a Finder pop-up dialog box stating "The Operation Can't Be Completed Because You Don't Have the Necessary Permission."

What? I'm the admin and computer owner. It lets me change the permissions for other files elsewhere on the computer, but it won't let me touch these.

Any ideas?

R,

Bill

OS X El Capitan (10.11), 13-inch; 4GB RAM; 256GB OWC SSD

P.S. Not sure why Apple won't let me edit my own post that started this thread, so I'll reply to myself here to tell everyone that the problem seems to be that El Capitan won't let me...the computer owner and admin....change this for ANYTHING in the System folder. At all. Period. Doesn't matter that I "unlocked" the padlock....El Capitan simply won't let me add any new users to the permissions block for any file or folder within the System folder, and it won't let me modify any EXISTING permissions at all. What the heck???

UPDATE:

From what I've read online, this appears to be the result of a new "System Integrity Protection" feature under El Capitan that doesn't let anyone, EVEN ADMINS(!!!), modify file permissions or add new users to the permissions list using the old "Get Info" pane.

So, just to be able to modify System folder and file permissions in El Capitan, one now needs to...

- Boot into the recovery partition

- Choose Utilities > System Configuration

- Uncheck Enforce System Integrity Protection

- Click Apply Configuration

- Restart your Mac

Geezuz, Apple...seriously...I have to go through all this just to change the hyper-irritating "Volume Mount" sound that you use when I simply copy or move a folder on my Mac???? Wow....just...wow.

You need to temporarily disable System Integrity Protection. Restart with the Command and R keys held down, go into the Terminal, and run:

csrutil disable

You can edit posts for up to 15 minutes after posting them.

Try disabling the System Integrity protection. Though it will render your Mac less secure.

Thanks!! That did it...

You should add that to get to the Terminal from the Recovery screen, one has to go up to the "Utilities" item in the menu bar...the Terminal is not presented as one of the OS X Utilities in the recovery splash window that is presented to users who rebooted using "Cmd R"

Also, how do I "re-enable" it? Is it just "csrutil enable" in Terminal? And am I correct that one has to AGAIN reboot into recovery mode (CMD R) to execute the command to re-enable it? Sigh...

Opinion Commentary: This SIP thing is really going to cause a lot of Mac users a lot of grief for a while....the ability to customize our Macs depends on being able to edit permissions and change certain things in the System folder from time to time. Having to go through this SIP disable process every time is a real hassle. I may leave it off for good.

Thank you so much for this! You are correct about the command "

csrutil enable"

Now I am able to finally create custom ringtones for Facetime and iMessages on my Mac!

For anyone interested in doing the same take a look at these links. Keep in mind before doing any of this you will certainly have to disable the System Integrity protection. But you can always re enable it when you are done.
