Garmin Express Not Detecting Devices on Newer Mac OS

Mac Catalina 10.15, Big Sur 11.0, Monterey and newer require permission to allow devices to connect with the Garmin Express™ application. You may see a message that Garmin Express would like to access files on a removable volume.

Selecting OK will allow Garmin Express to recognize the device.

Example of Prompt to Request Access to Removable Volumes

Selecting Don't Allow prevents Garmin Express from recognizing the device. This can be adjusted in the Security and Privacy settings on the computer if Don't Allow was accidentally selected.

NOTE: Some newer Mac computers may only have USB-C or Thunderbolt ports, which would require an adapter. Apple has a helpful support article that explains different USB types, how to identify them, and what adapters can be used: Identify the ports on your Mac.
If the Security and Privacy settings are set to allow Garmin Express to access files on a removable volume and the device is still not being recognized, refer to the articles below for additional troubleshooting suggestions.
