Chrome 31 for OS X, released three weeks ago, now supports Chrome Apps, Google's souped-up, cross-platform Web apps that are much closer to "native" software, the kind written for a specific operating system, like Windows or OS X. Chrome Apps can run without an Internet connection and call on several Google APIs and services barred to traditional website-based apps.
In September, Google previewed Chrome Apps and the associated App Launcher for the Mac in the early "Dev" build of its browser, but at the time said only that it would "soon" switch on the functionality in the "Stable" version.
Chrome for Windows has had Chrome App support since September's Chrome 29, with preliminary support going back as far as February. The Linux version of Chrome cannot yet run Chrome Apps.
Google has been pushing the packaged app strategy since its I/O developer conference in June 2012. Analysts have viewed the move as an attempt to subvert rivals' operating systems by using the popular Chrome browser as a Trojan horse.
