Can I run Holley EFI in Parallels on a Mac?
Yes. Install Windows 11 ARM in Parallels Desktop, then install your Holley tuning software and iCANDrivers inside the VM. Our driver enables the Holley 558-443 USB-CAN cable on ARM processors.
Holley EFI Drivers for Parallels Desktop
Parallels Desktop is the most popular way to run Windows 11 ARM on M-Series Macs. Install Holley tuning software inside the VM, add iCANDrivers for USB-CAN passthrough, and tune from the Mac you already carry—no Intel laptop required.
Setup Steps for Parallels
Follow this workflow to run Holley tuning software on Windows 11 ARM inside Parallels Desktop.
- 1
Install Parallels Desktop on your Apple Silicon Mac and create a Windows 11 ARM virtual machine
- 2
Enable USB device sharing in Parallels preferences so tuning hardware can reach the VM
- 3
Download your Holley software (Holley EFI, Sniper EFI, Terminator X, etc.) inside Windows 11 ARM
- 4
Purchase iCANDrivers and run the installer inside the Windows VM
- 5
Connect your Holley 558-443 USB-CAN cable, confirm passthrough to the VM, and start tuning
USB tip: In Parallels, assign the Holley 558-443 adapter to the Windows VM when prompted. If the cable does not appear, open Parallels → Configure → Hardware → USB and ensure automatic sharing is enabled.

Frequently Asked Questions
Which Holley software works with Parallels on Mac?
Holley EFI, HP EFI, Dominator EFI, Sniper EFI (Sniper 1), Terminator X, Terminator X Max, and Terminator X LF all work in a Parallels Windows 11 ARM VM with iCANDrivers.
Why doesn't my Holley cable work in Parallels without iCANDrivers?
Holley's stock USB driver does not support ARM processors, including Windows 11 ARM inside Parallels. iCANDrivers replaces that driver so the 558-443 cable communicates with your ECU.
Do I need a separate iCANDrivers license for Parallels?
Each license covers one machine or VM instance. If you tune from one Parallels VM on one Mac, one license is enough. Additional Macs or VMs need their own license.
