Developer Builds of Google Chrome for OS X and Linux Now Available
How incomplete? So incomplete that, among other things , you won't yet be able to view YouTube videos, change your privacy settings, set your default search provider, or even print.While the release indicates that Google is making progress on the OS X version of Chrome, it does appear that Google has significant work ahead in order to meet its previously-announced plan for launch in the first half of this year. Google Chrome offers three release channels ranging from developer previews to stable releases, indicating that the OS X version of Chrome has several thresholds to pass before it is ready for public launch.
Many Mac users have been looking forward to the public launch of Chrome for OS X and some have expressed frustration with the length of time it is taking to complete development of the Mac version. Google co-founder Sergey Brin even went so far as to call the lack of a Mac version alongside the Windows beta launch last year "embarrassing". But as Google developer Mike Pinkerton, who has been working on the OS X version of Chrome, notes with some frustration, deploying Chrome for OS X is more difficult than many think.
We're lucky in Chromium that we can leverage a lot of shared code from the windows side, but we do have to write a bunch of UI code (unless you want the UI to just look and behave exactly like windows...I didn't think so). We're also not just embedding WebKit and dragging in a couple buttons and a text field. The team has made significant changes to how WebCore works (resource loading, sandboxing, multi-process, etc) and those take time to get right on other platforms.
