Parallels 4 Released, 50% Faster Than Parallels 3

Parallels 4 Released, 50% Faster Than Parallels 3

Mac OS X only: The original Windows-on-Mac virtualization software Parallels—which we’ve used to run Windows and Mac apps side-by-side, set Windows programs as defaults on a Mac, and boot our Boot Camp partition from inside OS X—has just updated to Parallels 4. The good news: Parallels 4 boasts 50% faster performance than Parallels 3, while promising to use 15-30% fewer resources. Other new features include:

  • SmartMount: Access removable storage devices from both Windows and Mac at the same time.
  • SmartConnect: Instantly connect USB devices to Windows or Mac based on your set preferences
  • iPhone Remote Control App: Start up and shut down Windows, Linux or any other VM directly from your iPhone.
  • Modality View Mode: View Windows in a scaled view on your desktop for transparent viewing.
  • Clips Tool: Share several Windows or Mac screen captures to the Mac’s clipboard to paste into Apple Mail, iChat or Pages.

The only downside: Parallels 3 users will need to pony up $US40 for an upgrade. If you’re totally new to Parallels, a full licence will set you back $US80. We haven’t been able to compare the latest Parallels with its biggest competition, VMware Fusion, yet, but if you’ve tried both, let’s hear if you’ve noticed performance differences in the comments.


  • I have three problems after the upgrade:
    1) C drive is not visible in the Finder
    2) Copy and Paste doesn’t work either within Windows or between Windows and Mac. I get a “cannot open clipboard” message
    3) I have a USB device that I connect after setting Devices, USB, IEEE-1284 Controller, but since the upgrade this device doesn’t work.

    They have fixed the problem that prevented F11 and F12 function keys from operating properly for Windows applications.
