I'm on a job where there is a Nitris DX connected to the Mac Tower which recently has upgraded its OS to Sierra 10.12.6. Howerver the Nitris device which is connected via PCIe is not recognized by the system any more. The system says the driver is not installed. I just spent two days trying to fine that driver online with no luck. Does a Mac driver really exist? 

I found somewhere that mac's avid doesn't need driver as it's configured in Avid but then I found instructions on how to do it on a PC... so please please please does anyone know how to get it working again? 

(and I tried avid's download centre and all sorts of different links to it that just go to the generic main page where you choose a device - none of which are Nitris DX... :( :( )

Thank you in advance!

Which version of Avid is it?

Recently (8.9.3?) the installation of the DX driver became optional. The driver should be in /Applications/Utilities/Avid Utilities if indeed your Media Composer version is recent.

Email me directly and include your unit serial # and My Avid email.

Hi Pierreh,

The Avid version we're running is 8.4.1 so not the very recent one. 

Thank you Marianna, I just emailed you.

I've just upgraded to 2018.5 and I've run into two issues.

Issue 1 - I have installed the DX Drivers and made sure that they are up to date in the Application Manger but Avid does not recognize it.

For some reason it only wants to use the BlackMagic Decklink Card in my system. Protools sees it properly but not Avid. I need the DX because their are tape outputs with Closed Captioning that I must complete. What's the solution?

Issue 2 - Media Creation first dissapeared altogether then came back after I trashed all of the preferences and my user settings. Now whenever I load my user settings it is at the top of the settings list and is unnamed as in the attached screen shot. I will not chuck my user unlless their is some way for me to retrieve all of the Keyboard Layouts that I have on this system. Any suggestions would be helpful.

Starting a version or two back, you need to manually check "Avid DX Driver" when you install MC.

Confusingly, this is NOT related to what you see in AppMan.

I did do that when I did my first, second and third install of 2018.5 as well as the Sentinal Driver for my Dongle. I'm one of those guys who actually reads the Readme Files before doing major upgrades. I've also done the separate install hoping that that would fix the issue but it's still a no go. I've even trashed anything and everything that I can find in the Applications, System Library, Library and User Library Folders related to Avid and the issue still persists.

The DX is only recognized when I un-install the BM Drivers but disappears once I re-install them again.

This is incredibly frustrating because I end up un-installing the BM Drivers when I need Avid and then I have to re-install them when I need Resolve. What a pain in the ***.

Now for some reason it all works fine on High Sierra but there are a couple of things stopping me from moving up yet. Hopefully I can abandon Sierra soon so that I can bypass this major pain in the ***.

Has this ever worked? I'm not sure you can have both installed at the same time so that Avid uses one and Resolve uses the other.

You might need to consider dual-booting with two partitions...one for MC and one for Resolve, if you're intending to use the Nitris AND BM hardware.

Yes it has always worked. 2018.5 is the first version of MC and only on Sierra that has this issue.

There are four of us here running the same Mac Pros with the same configuratons and it's worked on Moutain Lion, Mavericks, Yosemite, EL Capitan and Sierra all the way up to 8.8.5 of MC. As I say I built a temp High Sierra boot and the DX even works there with 2018.5 and the BM Drivers installed so I'm really confused why it would be an issue on Sierra.

We have found the solution.

Use EasyFind to locate an Open I/O driver named "OpenIO_Blackmagic.acf" in up to two locarions. Once located, right click on each one and "Reveal in Finder", then trash each one from the folder that it has opened. Easy Find won't directly trash it itself and you will have to type in your admin password in when trashing each one. Next Empty the Trash.

This is an issue that has only started in Sierra and High Sierra for us.
