Headless Video Accelerator Don't settle for poor interface performance on your headless Mini. Take back the full power of your GPU today.
Never settle for a choppy interface.
Mac mini is an amazing little machine, packing phenomenal power into a compact form factor. It's fantastic as a headless unit for a high-power, whisper quiet home or professional server. But even with the mini's capabilities, when it's operated without a display attached, the GPU isn't activated meaning it's not pulling its weight. So when you access your mini remotely, the CPU does all the work rendering the user interface. The interface lags; OS X animation, cursor movement, menu navigation, and typing all suffer, making remote operations a pain.
Plug in. Restore Performance. Easy.
Now there's an easy NewerTech fix to make your remote experience run smooth again. The Headless Mac Video Accelerator makes your headless Mini think it has an attached display. This loads the video drivers, activating the GPU and taking full advantage of power, so your remote interface works perfectly – exactly how you'd expect. Plug in a Headless Mac Video Accelerator and get back to working smoothly on your headless mini.
