  1. I tried running IE9 in emulation mode under Virtual Box & Code Weavers then gave up as my tech-Fu wasn’t good enough to extend to command line code. I’m hopeless that way. I like my tech packaged in nice easy digestible bits, not chunks of raw meat that I have to convert to beefsteak.

    I finally gave up and installed Windows 7 in the Boot Camp partition. At least Apple guides me all the way in clear concise language and I don’t have to face anything harder than entering the licence key.

    1. You don’t need to know a bit of command line for Virtual Box. It is like Parallels/VMWare only free. And it walks you through the steps of installing Windows as well.

  2. Have used VirtualBox for a long time and just updated to 4.08. Have latest 64-bit Ubuntu (unity), Fedora, and Win7 running as guest O/S. Interactive and network performance equal underlying 64-bit Mac host with latest CPU tech. Very satisfied with this free, simple to install, and actively developed productivity solution.
