I just got an Issue with Connecting the Sensors on MacOS by the MIDI-Setup-Tool:
When i clicked “Connect” on the already known Sensors in the Setup, it showed that establishing the Connection is in Progress, but nothing happened.
Other Devices like my iPhone worked fine, so i updated the Firmware by using the Tutorial of @Fredrik (How to update the firmware - #3 by Fredrik). I got the same Result - No Connection possible on MacOS.
I went over to Reboot the iMac-Device, but this also didn’t solve the Connection-Problem. After this, i looked up the System-Settings of the Bluetooth-Connections and there you go - deleting the known Freedrum-Sensors and Re-Connecting it with MacOS solved the Issue!:
