Unfortunately we are unable to update your GPS on a MacOS Catalina. We are working with Apple for a swift solution to this problem. Please update your GPS on a computer with an earlier operating system, or on a Windows platform. Thank you for your patience.
The Mac Lezyne GPS updater is currently incompatible with the new macOS Catalina. Using it will disable your GPS device. We will have a new version available as soon as possible. If you have tried to update your GPS device on a Catalina OS, please plug your GPS into a computer running a previous OS, or a Windows OS, and run the updater to restore your GPS.
