Question about Ugreen Bluetooth 5.3 USB adapter

The Bluetooth 5.3 USB Adapter (Transmitter and Receiver) with product ID 90225 is officially compatible with Windows 8.1/10/11 according to the manufacturer's specifications. There is no official information regarding support for macOS Sequoia or 2009 MacBook Pro.
I recommend checking compatibility with the manufacturer, as newer operating systems and older models may not be supported. If in doubt, consult the Ugreen community for specific user experiences.
