Google Chrome Dev Now 64-Bit on Mac OS X

64-Bit Build Ahoy

Are you using the Google Chrome Canary or Dev Channel on your Mac?

If you are, and you’re on compatible hardware, then I have a little surprise: Google quietly updated Chrome to a 64-bit build without you noticing!

‘Google quietly updated Chrome to a 64 bit build without you noticing!’

The switch has been a long time coming. Most recent versions of Apple’s desktop operating system no longer default to the 32 bit architecture, a move that has seen some third-party plugins for the platform, like Java 7, offered only in 64-bit versions.

Chromium developers have been working on bringing native 64 bit builds of Chrome to OS X for a while. In fact, if you use the Canary channel frequently you may have already used one, as developers often seeded builds for testing there on occasion.

Now it seems as though that testing is ready to go wider. As of Chrome version 38.0.2065.0 on OS X, 64-bit Chrome is a-go on the dev channel:

What are the benefits of the switch? On paper: better performance and better multitasking. 64-bit builds allow Chrome to ‘address’ (read: use) more available memory on your system (assuming you have it) and perform more tasks concurrently, and faster.

Windows 64 bit Chrome builds have boosted performance by 25%, say Google, while also improving stability. Data on Mac performance has yet to filter out but it’s a promising indication nonetheless.

Getting Chrome 64 Bit Mac

On a 32-bit system? There’s no need to panic. Chromium developers have built a ‘fail safe’ into the server infrastructure that distributes updates to ensure that only compatible builds can install on compatible systems.

If you’re on a Mac I recommend rolling with the Canary channel. This installs alongside an existing version of Chrome, allowing you to use stable builds alongside it.

    I think they want to mainstream 64 bit on all platforms including Android, anything that uses chrome will see this update as part their next step to merge Chrome Os and Android together and i guess whats in between as well.

      Might not be far off indeed. I mean: (and no, I’m not an Apple user) Apple already has done this with iOS: it’s running 64-bit. So Android will probably follow suit as 64-bit on mobile devices progresses.

        I’m guessing there aimming to get it in before the Snapdragon 810 drops which will make 64bit SoC mainstream in Android.

    Great, now make the fonts on the bookmarks toolbar and tabs large enough to actually view on a 27″ monitor. Is everyone at Google and Apple nearsighted?

    i am enjoying the beta a low but it eats a lot of my 8gb ddr3 memory quite a bit (gonna upgrade my ram and add more)
