Chrome 38 beta for Mac makes jump to 64-bit code

updated 11:35 am EDT, Fri August 29, 2014

Google promises 'number of speed and security improvements'

For Mac users, the latest beta channel release of Chrome -- Chrome 38 -- makes the switch to a 64-bit codebase, Google has announced. The primary benefit is said to be speed, since it grants access to "a superior instruction set, more registers, and a more efficient function calling convention," according to Google. The company points out that in some cases Chrome can be the only 32-bit app that's running, forcing OS X to load 32-bit system libraries that consume extra memory and launch time.

Chrome for Mac is in fact dropping support for 32-bit NPAPI plugins, though 64-bit versions will be supported until NPAPI is stripped from Chrome entirely later this year. Google hints that Chrome 37 may be the last or next-to-last edition of the browser capable of running on first-generation Intel Macs.

The Windows beta channel is already on a 64-bit codebase. That could mean that the final release of Chrome 38 will adopt the technology as well.

    In "some" cases?

    Dropbox, Divvy, MySQL Workbench, Suitecase Fusion 5, BBEdit, virtually the entire Microsoft Office suite, Skype, FileMaker Pro, and yes, Apple's own built-in Dashboard are all 32-bit apps... just to name a few.

    Since Dashboard is active by default, I think there's hardly *ever* a case where Chrome is the only 32-bit app running. That statement by Google is nothing but a stretch of the imagination.

    Hold on, are you saying Google sometimes lies to manipulate people to follow the path they want them too like a mouse in a maze towards cheese? I AM SHOCKED.

    64-bit, in a web browser? Wow, the difference will be earth-shattering.
