Chrome/Chromium is compatible with 10.6 Snow Leopard right now as the minimum and goes all the way up to the latest so far. But it's not compatible with Leopard. Out of curiosity, do you think that it would be possible for me to take the open-source code of Chromim and port it over somehow to an older version of OS X such as Leopard? Or take the Linux version of it and port the source code over to OS X since it's possible to run UNIX apps over OS X like Cinelerra? If it's possible do you think it would be worth the time to get Chrome/Chromium (very similar, hard to tell the difference) ported over to like Leopard and even PowerPC Macs with Leopard using my older MacBook and share the app?
