I am a developer and working on a Macintosh. I have VMWare Fusion to boot windows. This is what I use to check if a site is running on IE and other windows browsers.
Now I came across this service: http://crossbrowsertesting.com/
This looks great and thinking of purchasing an account.
But I have allways wondered what other developers are using? What kind of tools (online/offline) do you use to test your websites on multiple platforms and browser versions? Remember, I am a Macintosh user.
