The method for installing the Baseus BA04 driver varies significantly between Windows and macOS. It is crucial to note that while Windows has robust support for MST (Multi-Stream Transport) docks, macOS has specific limitations.
At its core, the Baseus BA04 relies on the Realtek RTL8761B chipset. This specific hardware choice is significant because it dictates how the adapter communicates with the Windows operating system. On modern systems like Windows 8.1, 10, and 11, the BA04 is largely "driverless." Upon insertion, the operating system recognizes the Realtek hardware and applies a generic Microsoft Bluetooth stack. For basic tasks—such as connecting a wireless mouse or a simple keyboard—this automatic integration is sufficient. However, the generic driver often fails to unlock the full potential of the Bluetooth 5.0 protocol, particularly regarding High-Definition (HD) audio profiles and reduced latency.
