Capture one suddenly fails to find camera (Tethering)

Postby pbp » Sun Dec 30, 2018 1:16 pm

Hi I have a phase one 645DF and a leaf Aptus ii 8 40mb digital back.

My setup is a macbook pro running MacOs Mojave latest version.
I'm using a Unibrain FireRepeater 400™ ( ... 0-3-ports/) to connect my camera through thunderbolt.

This setup have worked fine until my last shoot, where I keep getting the same error in Capture one 11 and capture 12.

Capture one error:

Attach Camera
The chosen camera body is not compatible with the attached camera back.
Please choose a compatible camera body

When i get the error i can see in the camera tool of capture one that it does find Leaf Aptus-II 8. So what is wrong?

I find this really strange as the setup have worked fine for a long time?
So I really hope there are someone who can help me find this error?

So the short answer is macOS 10.12: Sierra, macOS 10.13: High Sierra, macOS 10.14: Mojave is kicking out/not recognizing the driver for most Aptus DBs. However not all OS's do this if the OS X 10.10: Yosemite has been installed first the drivers will be grandfathered for Aptus DBs.

OS X 10.10: Yosemite needs to be installed first for Aptus DBs to work. If any of the following OS is loaded first Aptus DBs will not connect correctly. OS X 10.11: El Capitan, macOS 10.12: Sierra, macOS 10.13: High Sierra. MacOS 10.14: Mojave will not work at all.

You still need to install Leaf drivers from C1 Pro v7 or v8 when running OS X 10.10: Yosemite

Return to Phase One and Leaf Legacy one-shot and scan camera back
