Wierd Tethering Issue
Hi,
I had the strangest problem with my Nikon D850 and the latest version of C1 Pro on a small commercial shoot today.
Up until now my D850 has been near bullet proof. It never dropped a tethered frame, never skipped a beat. I've been using Area51 cables and a fotofortress tether lock, and the setup to my M1 Max 64gb has been as close to perfect as I could ever need.
Somehow though on set today something went horribly wrong. The camera just wouldn't connect, or at least would briefly connect after a ton of error messages saying "Camera could not connect. The Nikon D850 is busy" but then just plainly refused to connect at all. I tried three different backup cables (all the same issue), different ports on my MacBook etc and nothing.
I got home now after the shoot and was playing around trying to get it to work. I could see in System Info in Sonoma that the Macbook could see the D850 so it was obvsiouly connected but still no sucess in C1 Pro. I removed all the memory cards, reset the camera, reinstalled C1, countless reboots of my Mac too and still nothing.
I have a Nikon Z6 as a backup camera and I tried to connect that to C1 and it worked perfectly, just to check it wasn't a software issue. I thought I'd try one last time with my D850 before I packed it up for repair, and wierdly enough it worked?!? It's back to being lightening quick, I can switch it on and off and it connects instantly just like it used to.
Does anyone know why this would happen? What would cause this to somehow not be able to connect to C1 yet but able to connect to MacBook? Any why connecting a different camera would have appeared to have reset this? I'm at loss to understand and I really want to make sure it's all OK as I've an important shoot coming up that would be a nightmare if this happened again!
Thanks a lot and best wishes,
Gavin

I have been unable to tether my D810 to CaptureOne for at least a month. I have Mac OS X Sonoma 14.5 on my Mac and can tether to Lightroom with no problem. I am also unable to tether with CaptureOne iOS (iPad Pro) but I am able to tether to Cascable on the same device. I have the latest version of all OSs and the latest version of C1 on both the Mac (C1 16.4.4.24) and iPad (don't know which C1 version but it's the latest one as of 10th Aug 24).
This is very frustrating. I've been pulling my hair out trying different cables and even connecting to a PC and it wasn't t until I installed Lightroom on the Mac and Cascable on the iPad that I could confirm it was a C1 problem and not something wrong with my hardware.

Make sure any other software that talks to the camera is not running (not even in the background). Any other software will compete with Capture One for control of the camera.

Thanks Walter. I didn't have any other connectivity software running at the time but I took a look at what was running in the background and these were:
1354 ?? 0:00.20 /usr/sbin/appleh13camerad
1355 ?? 0:00.03 /usr/libexec/cameracaptured
I killed them both and disconnected the camera. They both started again on reconnect but tethering now works. Fingers crossed but having disconnected and reconnected several times plus restarting Capture One, tethering came up each time.

Open Image Capture in macOS, look in the Devices section on the left, select your camera, and make sure the connect to camera setting is unchecked so it won't automatically try to grab hold of the camera.

I had already checked that though there is no "connect to camera" checkbox in my version of ImageCapture. Under D810 I had it set to "Connect to Camera opens: No Application".
I forgot to mention that I also killed ptpcamerad so I wonder if OSX is trying to use the D810 as a webcam though FaceTime etc are not running. So far it looks OK if I kill the daemons before trying to tether.
