Hi,
My Sony a 7RIV is not detected by SEM on my MacBook running Mojave. I have configured the camera as recommended in the digital camera configuration help files. I have also made sure that the camera is not connected to Photos ( "Open Photos for this device" box is not checked). I can see the camera under devices in Photos however. The camera screen shows "-PC-" setting. My old Nikon D 90 connects and is functional.
The firmware on the camera is up to date (ver. 1.20).
Any suggestions?
Thanks
Paul
