I thought I might have the solution to Pentax support because I discovered that my K5 can switch the USB connection to PTP. This prevents the it from being mounted when connected to a mac. When I started INDI it even confirmed use of PTP - warning of blocking Canon or Nikon. However, I get this error message:
2017-09-06T00:19:12: Can not open camera: Power OK? If camera is auto-mounted as external disk storage, please unmount it and disable auto-mount.
2017-09-06T00:19:12: Camera open error (-53): Could not claim the USB device
PS: I'm using Kstars 2.8.2 for mac but it show that its using indi_gphoto_ccd which I think may not be gphoto2 as I was expecting.
