On my iMac, the Varia Vision does not appear in Finder as an external USB drive, when I connect it directly to the computer via a USB cable. So Garmin Express cannot find it. Garmin support shipped me a new USB cable, but it still fails to connect. The Mac is running the latest High Sierra OS. However, the Vision does connect fine on a Windows 10 PC that I have, as well as a MacBook running the older El Capitain OS. What could be wrong with connecting on the iMac?
Furthermore, here is the USB info for the Vision from System Information on the iMac:
Product ID: 0x295e

It is incomplete. Basically, it is not being recognized as an external drive. On the MacBook where it does work, it shows different information:
