How do I test if a website works on an old Mac without owning a Mac? Are there emulates. Does Safari work the same on both XP and a Mac? On the PC the website works on ie 7-9, FireFox, Opera, Safari, and Chrome. It works on a very old iPhone too but not a five year old Mac. Here is a screen shot of I just got from Browser Shots on Safari 4.0 which is exactly how it's supposed to look.
