- Having never heard of NetExtender before, I can only go on how you've described it in your post, and I have to say, Macs don't need third-party programs to perform 'maintenance' on them. One thing I can say is that before you upgrade your operating system, you should always make sure that all of your applications, plug-ins, drivers, extensions.
- NetExtender stays resident on the client machine even after the connection is closed. The advantage of running NetExtender as a resident application on the remote system is that it speeds up login times in subsequent uses. Of course, if a remote user chooses to deploy the standalone NetExtender client on their remote.
NetExtender - Clientless connectivity removes the need for a pre-installed or 'fat' VPN client, thus freeing administrators from the tedious and costly task of installing and updating a client on users' Windows, Mac or Linux-based systems. NetExtender technology provides enhanced capabilities such as network level access to additional.
If you are trying to install Dell SonicWALL NetExtender (it's a VPN client) on OSX El Capitan, you might run into a situation where it won't connect to the VPN server and you might see this in the logs.

Apparently, there is a new feature called ‘System Integrity Protection‘ in OSX El Capitan, which restricts the root account to do perform certain actions.
System Integrity Protection is a security technology in OS X El Capitan that's designed to help prevent potentially malicious software from modifying protected files and folders on your Mac.
In OS X, the 'root' user account previously had no permission restrictions and could access any system folder or application on your Mac. Software gained root-level access when you entered your administrator name and password to install it and could then modify or overwrite any system file or application.
System Integrity Protection restricts the root account and limits the actions that the root user can perform on protected parts of OS X.
So, in order to fix the issue at hand, the System Integrity Protection (SIP) must be disabled first, then NetExtender must be installed and SIP must then be enabled back again. Here is MacWorld's article on how to do it. Basically, these are the steps :-
Netextender Client Mac Download
- Restart your Mac in recovery mode (hold CMD+R during restart)
- Go to Utilities menu and open Terminal and type in the command ‘csrutil disable'
- Restart Mac again and run the command ‘sudo chmod u+s /usr/sbin/pppd' and then install NetExtender again. Try connecting to VPN and confirm it works this time.
- Restart Mac again in recovery mode and run command ‘csrutil enable'
SIP enabling/disabling might be needed for a lot of other reasons, however, I needed it today to install NetExtender. But the same steps could be followed for any other command that's been restricted because of this new feature.
Having never heard of NetExtender before, I can only go on how you've described it in your post, and I have to say, Macs don't need third-party programs to perform 'maintenance' on them. One thing I can say is that before you upgrade your operating system, you should always make sure that all of your applications, plug-ins, drivers, extensions, etc., are compatible with what you're upgrading to. That could be part of the problem, should this program not be what I think it sounds like. Are you running the most current version, and is that version compatible with El Capitan?
