Desktop Video M1 Chip Macbook Air "No Device Detected"

Hi guys,

I'm setting up a 2020 Macbook Air with M1 Chip running OS Monterrey 12.4

I have installed Desktop Video 12.3.1 in the hope of running my UltraStudio Express (Something I have done with previous Macbooks and previous versions of Desktop Video without issue)

I have gone so far as to alter the security settings in recovery mode to allow user management of kernel extensions.

My 'system report' identifies the UltraStudio in the Thuderbolt/USB4 port and provides the below detail...

---------------------------
UltraStudio Express:

Vendor Name: Blackmagic Design
Device Name: UltraStudio Express
Mode: Thunderbolt
Device ID: 0xA127
Vendor ID: 0x4
Device Revision: 0x1
UID: 0x000400000084DC90
Route String: 1
Firmware Version: 7.1
Port (Upstream):
Status: Device connected
Link Status: 0x2
Speed: Up to 10 Gb/s x1
Port Micro Firmware Version: 0.2.5
Cable Firmware Version: 1.0.16
Cable Serial Number: C4M6381023RF797AV
-------------------------

I have noticed that in "/Library/StagedExtensions/Library/Extensions" I only have "BlackmagicIO.kext" where as on my 2016 Macbook Pro I have not only that file (or similarly named) but also "Blackmagic_Multibridge_Driver.kext" and "BlackmagicUsbIO.kext"

The outcome of all of the above is that I cannot get Desktop Video to detect the Ultrastudio Express when launched. It displays the following message...

"No Desktop Video Device Detected. Please check that your product is connected via Thunderbolt, USB3, or PCIe and is powered on."

I should say that I have very limited knowledge of OS Monterrey and most of the above points of interest I've gleaned from forums, so excuse me if I'm mentioning redundant or irrelevant points.

Any help would be much appreciated.

Thanks,
Jason

I have tested an UltraStudio HD Mini and it worked fine, so no problems with software or security permissions.

Some older I/O devices by BM or not compatible with M1.
IIRC there’s a list at their site somewhere. Ok

The Macbook Air M1 and M2 are limited to one external monitor only, but does it view an Ultrastudio connected to a reference monitor as a "monitor," or something else? In other words, would I be able to run both a regular 4k monitor and a reference monitor for grading from the Macbook Air, if the reference monitor is connected to the computer via an Ultrastudio Monitor 3G or an HD Mini?

I assume the answer is "no" but would be pleasantly surprised if it were "yes."

Yes.
The ultra studio will enable a grading monitor being used in apps like resolve and others which support the US3G et al. You will not be able to use that monitor as an ordinary monitor in macOS though.

It’s basically a dedicated data stream fed into the ultra studio and displayed on the grading monitor.

That said you would need power to feed the MBA, a usb-c to display cable and the ultra studio over TB3.
But you only have two TB3 ports.
So you would probably need a powered TB hub like the OWC 4-port TB hub. But I’ve never used them with a MBA. But the arrangement works smoothly on a M1 Mac mini and MBP M1.

Fantastic news, thanks! I have the Caldigit TS4 hub (amazing but expensive), so this will work well.

I work only with 1080p footage, mostly ProRes HQ but sometimes CDNG raw 3:1 and the Air should handle it just fine in Resolve though I haven't stress-tested it yet. It might throttle during rendering but that's okay with me, I am working only on personal projects with no deadlines. I have the M2 Air with 24 gigs of RAM, 8 core CPU and 10 core GPU. It's kind of amazing that this little computer can replace my 2013 Mac Pro trashcan with 32 gigs of RAM and dual GPUs, but it looks more than capable. I also do on-location music recording and having a silent laptop is key for that purpose, otherwise I would have gotten an M1 or M2 Mini or Studio.

I just ran a test from my MacBook Pro M1.
USB-C to DP in on Eizo @ 2560 x 1440.
TB-3 to US Monitor to HDMI 1080p24 in on Eizo for grading in rec 709

Worked good in both Resolve and FCPX.
I did not feed the MBP with power via the OWC TB Hub but I know that the TB Hub works perfect with both power to MBP as well as with the 3G US Monitor/Recorder.

Thanks! I have to upgrade my Ultrastudio (I have the first-generation mini monitor) but didn't want to spend the money until I was sure it was going to work with my new setup. Thanks for confirming.
