Another CUDA Issue

My apologies if this has been answered, I can't find any posts with my exact problem.
I've got a late 2012 iMac, running Sierra 10.12.1 and NVIDIA GeForce GT 640M 512 MB.

I've been running Resolve 15.01.003 Beta free version with no issues at all.

I bought a used BMPCC that included a dongle with Resolve 12.5. It gives me the "can't find CUDA" error message. Is there anything I can do to make 12.5 work? I'd think if 15 is running with no problem surely 12.5 should be able to as well.

Thanks in advance for any help.

The dongle will work with the current release version.

You don't need to use 12.5. The Resolve dongle will work with any Resolve version.

!5.01.003 is not a beta version, it's a release version. If the free version was working on your system, download and install the Studio version and connect the dongle, and it should work.
