Google quietly updated the Mac OS X version of Chrome to 64-Bit. This happened with the recent Developer channel and canary build updates. This means we are only weeks away from 64-bit Chrome on Mac.
I am sure there will be a lot of happy campers on the OSX land now, because Apple has shown their preference to 64-bit, even on their mobile operating system.
Windows 64-bit version of Chrome is currently in beta. I am assuming that we will see an announcement for Chrome 64 bit versions for all platforms together, very soon.
So, wait for a big announcement post on the Google Chrome Blog soon.
