Setting up VCDS (Vag-Com Diagnostic System) on a Mac using Parallels can seem daunting, especially for those unfamiliar with virtualization software. This guide provides a step-by-step walkthrough of a successful VCDS installation on a Mac using Parallels, including solutions to common issues.
Overcoming Initial Challenges with VCDS and Parallels
Initially, connecting the Ross-Tech Hex V2 interface to a Mac via a USB-C to USB adapter and running VCDS within a Parallels Windows 11 virtual machine presented challenges. The system repeatedly reported that the USB cable was not plugged in or recognized, despite a successful physical connection. This common problem stems from how Parallels manages USB devices.
Configuring Parallels for VCDS Compatibility
The key to resolving the USB connection issue lies in correctly configuring Parallels’ USB device settings. By default, when a new USB device is connected, Parallels offers three options:
- Connect it to the Mac
- Connect it to the active virtual machine (Windows 11 in this case)
- Ask what to do
Initially, selecting the option to connect the Hex V2 to the Mac resulted in persistent connection errors within VCDS. The solution was to change this setting.
To ensure VCDS recognizes the Hex V2 interface:
- Access Parallels Preferences: Go to Parallels Desktop -> Preferences.
- Navigate to Devices: Select the “Devices” option.
- Restore Defaults (if necessary): If you’ve previously modified USB settings, clicking “Restore Defaults” ensures a clean starting point. This will revert to the “Ask me what to do” option for new USB devices.
- Connect and Select Windows: Disconnect and reconnect the Hex V2 USB cable. Parallels will prompt you to choose where to connect the device. Crucially, select “Windows 11” (or your Windows virtual machine).
Successful VCDS Setup and Testing
After correctly assigning the USB device to the Windows virtual machine, the Ross-Tech Hex V2 was recognized within VCDS. Following the standard Ross-Tech instructions – clicking [Options], [Test], and [Save] – resulted in a successful test and confirmed proper functionality. A subsequent vehicle scan further validated the successful VCDS installation. This configuration allowed for seamless operation of VCDS on a Mac using Parallels and a Windows 11 virtual machine.
This experience highlights the importance of correctly configuring USB device settings within Parallels to enable communication between VCDS and the Ross-Tech Hex V2 interface. By ensuring the Hex V2 is connected to the Windows virtual machine, users can avoid common connection errors and leverage the full functionality of VCDS on their Mac systems.
