I work on a Mac and have been testing with Parallels for years.  I have not been able to test IE9 or 10 without shelling out for Windows.  I do not understand how to work a PC, which is partly why I am in this bind.

These instructions:

1.  Download all SFX and RAR files for the VM.
2.  From the terminal, allow the downloaded file to execute by typing chmod +x filename.sfx on the SFX file only.
3.  Run the SFX file from a terminal, such as by ./filename.sfx and it will expand into the PVM you can open with Parallels.

On this site:  http://www.modern.ie/en-us/virtualization-tools#downloads after selecting Mac, Parallels are somewhat Greek to me.

My questions please are these, referencing the install steps above:

1.  I assume I am downloading these from within Parallels, and not via a browser in my iOS?
2.  "From the terminal".  What does that mean?  Do I click on the Start button and then the Run option, and then type what is given?  Is that it, or something else?
3.  "Run the SFX file from a terminal" - again, what does that mean?  How do I do that?

Any other tips given my obvious ignorance on how to install this would be appreciated.  

And finally, I am running Parallels version 7.  Do I need version 8 to run these?

Thanks so much.
