Can't connect Nextetender on Mac OS-X El-Captain

Question

I just upgraded from Yosemite to El Captain but I can't connect Dell SonicWALL NetExtender version 7.5.757. I give this log message:

[general error 463] ERROR: Pppd is not setuid-root and the invoking user is not root. (3)

[general fatal 463] Please delete and reinstall NetExtender, or run chmod u+s /usr/sbin/pppd an administrator.

then I tried delete and reinstall NetExtender but not working. After I tried sudo chmod u+s /usr/sbin/pppd on terminal but I give this massage:

chmod: Unable to change file mode on /usr/sbin/pppd: Operation not permitted

Solution 1

Dell SonicWall NextExtender is not compatible with Mac El Captain. There is a software which enables this you can download SonicWALL Mobile Connect, which is released by SonicWALL, from below link: https://itunes.apple.com/us/app/sonicwall-mobile-connect/id822514576?mt=12

Solution 2

I had this problem after upgrading to El Capitan and read the stackoverflow post suggested by giraysam. Added one more step in order to make the fix to NetExtender:

• Have the NetExtender .dmg install file in a handy location, like your desktop (you will have to reinstall NetExtender)
• Reboot the Mac and hold the Cmnd+R keys to reboot in recovery mode
• Once in recovery mode, select Utilities -> Terminal from the menu bar
• Execute the following command: csrutil disable
• Reboot the Mac (do not hold any keys)
• Open the terminal window and execute the following command: chmod u+s /usr/sbin/pppd
• Reinstall the NetExtender program
• Connect to your VPN with the NetExtender program - It should connect successfully
• Log off your VPN and reboot your Mac. Hold the Cmnd+R keys to reboot in recovery mode
• Once in recovery mode, select Utilities -> Terminal from the menu bar
• Execute the following command: csrutil enable
• Reboot the Mac (do not hold any keys)

That worked for me. Hope it helps.

FYI: csrutil command is used to configure Mac's "System Integrity Protection", introduced in OS X 10.11 El Capitan. More can be seen in Mac Developer LIbrary
