I use modernizr to support some html5 features (like placeholder or different input types such as date, number) for my website. However, the current browsers in my mac (chrome and safari) support html5 and I don't have any chance to test my website in a browser that doesn't have html5 support.
What's the best approach to test a website under the non-html5 conditions? Downloading an html5 incompatible browser (if so example please) or a tool ?
Since you're on Mac (so am I), the images provided through modern.ie might be more helpful. They have vm images for VirtualBox and VMWare, in addition to VirtualPC.
