This is interesting – a software letting you run IE 5, 5.5., 6 and 7 (beta) on your Mac without needing parallels. This could be great for testing.
Its called ies4osx and requires OSX tiger or leopard, and an Intel machine. On tiger you need have to installed X11.
I found the download process pretty simple, a few things to do,
but nothing too time consuming.
