# the admin password for all of the IE VMs is “Password1″ without the quotes, it's also used for the password hints

1) Install VirtuaBox on your mac

http://download.virtualbox.org/virtualbox/4.1.10/VirtualBox-4.1.10-76795-OSX.dmg

2) Decide which versions of Internet Explorer you want to download and install – each version of Internet Explorer is contained within a separate virtual machine that runs within VirtualBox. In other words, if you want to run Internet Explorer 7, 8, and 9, you will need to download three separate VM’s, which may take a while so keep that in mind. Select the text below and copy it:

# Install ALL versions of Internet Explorer: IE 7, IE 8, and IE 9 (for now this script will also pull down a IE 6 vm with windows xp)

just change out app_name for your purposes

openssl genrsa 2048 > app_name-wildcard.key

openssl req -new -x509 -nodes -sha1 -days 3650 -key app_name-wildcard.key > app_name-wildcard.cert

# Common Name (eg, your name or your server's hostname) []:*.app_name.com

openssl x509 -noout -fingerprint -text < app_name-wildcard.cert > app_name-wildcard.info
