Nov 29, 2015 4:05 PM in response to db24401by bigschwabbel,★HelpfulInternet Recovery would have been the easiest way. But an early 2009 Mac Pro is too old. Only these older models have received an updated firmware.

Nov 29, 2015 4:03 PM in response to Dakoomby bigschwabbel,★HelpfulSIP can only be disable when booted from a recovery system.
ATTENTION: Whatever you decide to do, have a recent backup of your data.
Your options are:
1. Check your boot menu for a recovery system. Boot your Mac with the OPTION key pressed.
2. Check your system drive for a partition called "Recovery HD". Open Terminal and type "diskutil list". Hit ENTER.
3. Repair your system drive by reinstalling El Capitan without erasing your data. That would create a new recovery partition. But that only works if your system drive doesn't contain a RAID configuration or an odd Bootcamp configuration.
4. Make yourself a bootable El Capitan Installer flash drive. That would give you a recovery system.
5. Install El Capitan on another drive. That would also create a recovery partition that you could use to disable SIP.

Nov 29, 2015 4:05 PM in response to bigschwabbelby Dakoom,Thank you a lot guys for your replies.
I think that I only have these two options now:
4. Make yourself a bootable El Capitan Installer flash drive. That would give you a recovery system.
- I have a 40gb hard disk USB. How can I do it with it? I already have the El Capitan installed file downloaded.
5. Install El Capitan on another drive. That would also create a recovery partition that you could use to disable SIP.
- The same as above, how could I do this?

Nov 29, 2015 4:56 PM in response to leroydouglasby Dakoom,Ok, done, then I have to hold down Option during install and then I'll find a terminal where I can use csruit disable, right?
EDIT: I tried rebooting and the I pressed Option, but it doesn't work for me. Nothing happens and I'm redirected as normal to the login page.

Nov 29, 2015 5:42 PM in response to Dakoomby leroydouglas,Yes restart holding the option key. You should see the startup manager— plugin your SDcard, USB or where ever you installed the Installer.
Boot off the Installer, Quit the installer if necessary, from the drop down menu you will see the terminal

Nov 29, 2015 5:56 PM in response to leroydouglasby Dakoom,It doesn't work for me. If I go to System Preferences - Start Disk I only have my current HD. The USB drive is not showing up.

Nov 29, 2015 6:06 PM in response to Dakoomby leroydouglas,You may not see it in System Preferences— there is a known El Cap glitch there.
Restart option key is the way forward. Verify your createinstallmedia was carried out correctly. If it is not bootable it will not show up.

Nov 29, 2015 6:16 PM in response to leroydouglasby Dakoom,Nope, it is not working. I press Option key but nothing happens. I think the USB is working. I received no error message with the command line I entered before. Here is an image:

What else could I try?

Nov 30, 2015 11:02 AM in response to Dakoomby bigschwabbel,To be honest with you, I'm not sure you're doing the "Restart + Option key" thing the right way. Please follow this procedure, just to be on the safe side.
Remark: On some non-US keyboards the OPTION key is labeled as "ALT" or "alt". Again, just to be on the safe side.
1. Shut down your Mac. Wait for it to completely turn itself off.
2. Press and hold the OPTION key on your keyboard. While still pressing the OPTION key push the power button on your Mac. You're still keeping the OPTION key pressed.
3. After a few seconds you will get one or more icons of your disk or disks. Everything that's bootable on your system will show up now. Let go of the OPTION key now. One of the icons should say "Macintosh HD" or whatever you've named your system drive. Another icon should be named "Install OS X El Capitan".
4. Choose the drive called "Install OS X El Capitan". Your Mac should now boot the OS X Installer environment.
5. When the menu bar appears at the top of your screen, choose "Utilities -> Terminal" and continue with the csrutil command.
If that's what you have done, and it still doesn't work, you might have an odd hardware or software configuration or a defect.
Just a thought:
I have a Mac Pro (mid 2012) here with a Sonnet Tempo PCIe card, which connects my SSDs to my system. I can't access the boot menu while this card is installed. Do you by any chance have a card or other hardware installed, that might prevent you from using the boot menu?

Nov 30, 2015 12:03 PM in response to bigschwabbelby Dakoom,Thank you so much! Now it works and I get back my Audio Interface! Thank you! Thank you!
Basically I was holding down the Option key after the Mac was started, not before the Power On button! This was the problem!
Thank you all for your help!

Jun 29, 2016 6:57 AM in response to bigschwabbelby Duane Maas,If you have another computer with Yosemite or earlier installed, you can boot that computer, then mount the computer with El Capitan on the hard drive using target mode copy your files to the /System directory.
