Answer
Unfortunately, the BT851 does not officially support macOS. While the device utilizes default drivers of the host system and works with Windows, Linux, and Android Bluetooth software stacks, Apple’s macOS is not compatible.
This is because macOS does not support the Classic Bluetooth Serial Port Profile (SPP) that the BT851 relies on. Instead, Apple uses proprietary protocols such as Apple MFi and iAP, which require a dedicated Apple chip that the BT851 does not contain.
Note: Customers are free to explore potential compatibility using third-party tools or software solutions that might bridge the gap, though this is not officially supported or guaranteed by the manufacturer.
