Hi there, I’m using a MacBook running the latest version of OS-X (10.13.2). I have downloaded the CCD Ops light and it seems to communicate with my ST-i although focus captures 1 frame and then stops. The same seems to happen when I select a dark frame. I got to wondering whether it could be camera firmware related so I tried the firmware updater. The query got me the camera so I tried to download the latest drivers. I get an error saying that the 3r2 folder could not be created. This is odd because I have permission in the folder I’m running it from. Can you suggest a course of action? regards Bruce Toronto
