Microsoft Natural Ergonomic Keyboard 4000 won't work on OS X El Capitan

Changes to security in El Capitan makes the current IntelliType software unusable. Microsoft hasn't updated the software since Lion. They're going to have to actually do something with it now.

I too am having the same problem. I reached out to MS Support on this via twitter. They responded to my request for more info, but haven't heard back from them since. Been 4 days. Sounds like MS has lots of issues with El Capitan.

I will try Karabiner. Thanks for suggestion.

Karabiner is working great for me. Hope it works for you as well.

There is a way to get IntelliType 8.2 installed and working, and still have System Integrity Protection enabled.

1) Boot to the Recovery partition, or a flash drive El Capitan installer you've created. Click Utilities on the top menu bar, choose Terminal and enter:

csrutil disable

Restart normally back to El Capitan.

2) Install IntelliType. You'll be told it's an unsigned app if you double click the installer. So right click on it and choose Run. You'll notice part of the dialogue that goes by as it's installing is that components are being registered with the system. That's the important part. El Capitan now recognizes it as "okay". There of course is the restart the IntelliType installer does to finish.

3) Now that IntelliType is installed, once again boot to the Recovery partition and this time in Terminal enter:

csrutil enable

4) SIP has now been re-enabled, so you have the extra protection El Capitan brings with it, and IntelliType is still installed and functioning.

Worked like a charm, thank you! 🙂

Thank you! It worked for me, too.

Kurt: There was no:RUN

So right click on it and choose Run when I right clicked on my Mac Mini with El Capitan

Sorry for the typo. Should have been "Open".

Thank you so much for this workaround! It's funny how we get used to everything being setup just the way we like it then something comes along and breaks it and someone will come up with an awesome workaround for it 🙂.

SIP is a very good idea, so I give credit to Apple for taking OS security very seriously, and not waiting until something major happens before doing anything about it.

MS has twiddled their thumbs over this software for years. Now they have to do something about it so it works as it should and not the user having to juggle things around to get it to work. We were fortunate it worked at all.

User VikingOSX actually kind of gave me the idea. He mentioned to someone else to try this little trick to get drivers installed for some expensive software that wouldn't work under El Capitan. And I thought, "Hey, I wonder if I can do that with IntelliType?"

I installed El Capitan over Yosemite today for no reason other than to get a Recovery partition on the drive, then restored Yosemite back to that partition. In the process, El Capitan is supposed to (from what I've read) leave such older drivers installed and working. Wrong. IntelliType was dead after the install was complete. So I would expect that in the future if a user reinstalls El Capitan over itself, or applies the full installer of an update, like 10.11.1 when we see that, it may break IntelliType again. Then you'll have to go through this whole thing again to get it working. Or (HA HA!), MS will finally update this software so it installs the way it's supposed to.

... Or (HA HA!), MS will finally update this software so it installs the way it's supposed to.

I wouldn't expect it too soon (if ever) with all their other issues with the latest Office on Mac

and their galaxy full of issues with Windows 10 and there lack of any idea of where

they are really heading in the future.

Thanks Bill! The screenshots helped a ton.

Yeah! It works for me now. Thanks for sharing.

I'm using MS Desktop 3000 and I also became angry when I noticed that it was not compatible with El Capitan. But I found the solution. I switched to a 3rd party software. Try USB Overdrive http://www.usboverdrive.com/. It's a shareware and is free forever. The only limitation is a popup notification to upgrade when you start your computer.

I hhaven't upgraded yet but it's something that I will consider if MS didn't solve the issue.

And the good thing about USB Overdrive is that.. it was able to customize buttons that IntelliType didn't allow me to.. For example, now I can customize Number Lock Key (on the number keypad), Insert Button, and everything else. The only problem is.. it was not able to detect 5 special hotkeys. Otherwise, it's just perfect.

Good luck!
