Questions 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.

The adapter supports the A2DP profile, but there is no specific information on whether it also supports the aptX profile. A2DP is used for the transmission of audio content, while aptX is a special technology to improve audio quality. If you want to make sure whether aptX is supported, I recommend contacting the official product description or the manufacturer.
