Having just Firefox and Safari as the only two options is probably not enough for many Mac users. There is always a mixed emotion. And most users don’t mind a third browser to step in. (Sorry, no offense to Opera fans but Opera for Mac is yet to prove itself worthy). After a commendable success of Chrome for Windows, Google finally released the first official beta version of the browser, exclusively for the Mac. Speed remains blazingly fast as usual while the user interface looks Mac-ish. Google probably considers G4/G5s as obsolete, so no support for them. Seems Chrome is only meant for OS X 10.5 or above.
Take a quick test drive, you will not be disappointed.
