Mac users got a beta 64-bit Chrome back in August and today it’s reached its stable release. The browser has been fully optimized for 64-bit Macs and will take full advantage of your computer’s processor and graphics card.
Chrome 39 marks the introduction of 64-bit Chrome but also the death of 32-bit Chrome on Mac. You can only download the 64-bit version of Chrome for Mac now, which shouldn’t be a problem for most users running a fairly modern Mac.
64-bit Chrome boasts faster speeds and better utilization of your Mac’s hardware. This means your browsing will be snappier than ever, though you may see an increase in memory usage.
To get the update, click on the menu button inside of Chrome and select About Google Chrome. The update will appear and you can choose to download and install it. If you’re not seeing the update, you can download it yourself below.
