I bought a couple of the Cateye Sync lights a Front one and two rear ones. Charged them up and eventually managed to get them to register on the the iOS app which then told me I had to update the Firmware on the lights, so.....
I'm using a Mac running OSX 10.15 and I've downloaded the Cateye Updater app that works with 10.15 but it only displays instructions to start the update process and then nothing happens.
Anyone managed to get this to update the Firmware?
