On macOS, the process is slightly more complex due to security permissions. Modern versions of macOS include a native driver for CH34x chips, but it often conflicts with third-party JXMCU drivers. If your board isn't appearing, you may need to go to System Settings, then Privacy & Security, and "Allow" the driver software to run. For older Mac systems, a manual installation of the signed CH34x V1.5 driver is usually the standard fix.
Before installing software, it helps to understand why the driver fails. Most JXMCU boards utilize a specialized WinChipHead (WCH) microcontroller architecture.
