Digg's Kevin Rose, perennial purveyor of information that just "fell off the back of the truck" shared a link early this morning to Google's new, supercharged, Webkit-based browser -- for Mac.

The new browser, Chrome, is clearly marked as a developer preview, and not meant for general browsing. In fact, as a good Mac citizen, it will refuse to set itself as your default browser.

It scores a 100 on the Acid3 test straight out of the box, but doesn't pass: it fails something called the linktest, which involves interacting A tags and IFRAMEs. A little research suggests that it could be a bug with Webkit. If that's true, then it's a bug that Safari 4 beta has fixed.

Chrome appears to have Flash (and other plugin) support disabled as well. JavaScript support, however, is fully functional. While Chrome performed much better than Firefox on this cursory test, it still didn't beat Safari 4 by a long shot. While only a beta, its performance is respectable and sure to improve.

Again, Google Chrome isn't for everyone, but if you're a web developer who needs to keep up with the bleeding edge of browser development, then this preview should be stable and reliable enough for you to test what you need to.

Read through for the full JavaScript test details.

Thanks to everyone who sent this in!

After much lamenting and a few attempts, Google Chrome can finally be run natively in OS X. Kind of. Don't get us wrong, it works: it starts up fast and runs one process per window, just like the Windows version. But there are a few glaring holes, the lack of plugins (and therefore Flash, which means no YouTube) being one of them. The History, Bookmarks Bar, and Preferences screens don't work either, which makes this not much more than a proof-of-concept still: it can run natively, but you wouldn't really want to.

It's too bad Google hasn't gotten this working themselves sooner. Maybe they've just been too busy lately taking care of panda-obsessed AIs.

Gather around, Apple fans. I have good news and bad news for you. The good news is that there is a preliminary version of Google Chrome up and running. Sort of. Google's Mike Pinkerton has posted a couple of screenshots of Chrome for Mac on his blog, including the very first time he used it to load a webpage. It's coming, folks.

Now the bad news from Mike himself, "We've got a very very long way to go." He says that the WebKit that ships with Mac OS X doesn't do what they developers need right out of the box, and it took a lot of cajoling to get it to comply. If it's anything like the acrobatics I must perform each weekday morning to get my kids out the door in time to catch the school bus, Google's Mac devs will be busy indeed.

At this rate, Google won't even have to release Chrome for Mac OS X -- our devs will have done it all already themselves. We've already reported about CrossOver putting their own port of Google's web browser together just to show they could do it, and now word has come in about Stainless, another attempt to bring Google's Chromium kit over to our favorite operating system.

Unfortunately, it's still just a tech demo and not really a full-fledged browser (and the guys behind it, Mesa Dynamics, say that they didn't even try doing the cool stuff that the real OS X Chromium team is working on). But they did create a multi-process browser (one per tab), and they used some of the tech from their other app, Hypercube (Edit: NOT HyperCard, sorry -- I would have been more excited about that, too) to do it. I haven't tried it (I haven't tried the real Chrome on Windows either, Firefox is good enough for me so far), but like the other OS X Chrome, this app really only exists just so it can.

And it shows just how desperate OS X users are to get their hands on Google's browser. Just how much longer do we have to wait?

The Omni Group has released version 5.8 of OmniWeb, its venerable browser software.

OmniWeb 5.8 is now based on the same version of Webkit as Safari 3.1.x. It also fixes bugs with Spaces, and adds support for non-POSIX file URLs. Users can also choose Google Chrome in the list of user-agent strings. Full release notes are also available.

OmniWeb 5.8 is available from Omni's website, and works with Mac OS X 10.4.8 or later. The software is $14.95, with upgrades starting at $4.95 for users of Omniweb 4.

Mike Rose and I were chatting about this on the Talkcast a few weeks back -- virtualization and emulation programmers get all John Locke from Lost when you try to tell them what's not possible. And so when the guys at CrossOver heard that Google wasn't releasing Chrome for the Mac, they decided to put together a release themselves. CrossOver Chromium is a proof-of-concept release of the Chromium browser (which Chrome is built off of) that allows Google's base code to run on Mac and Linux platforms.

It's designed to show off just how well Wine works to bring Windows-based code to other platforms, and wake Google up to the fact that if they wanted to port Chrome over, they could. CrossOver says they did this to prove a point (and the point seems proven), but it's likely not only that Google wants to run the code natively, but that they wanted to focus on their largest audience first, which anyone can tell you is likely still the Windows crowd.

Even CrossOver says their version isn't ready for prime-time yet, they just wanted to show how fast it could be done. Let this be a lesson, Google: don't tell virtual software developers what they can't do.

Google is developing a new web browser built from the ground up and based on WebKit, the same rendering engine that Safari uses.

The browser, called Chrome, is open-source software built with security, compatibility and speed in mind. Each tab in the browser will be its own separate running process. For example, if JavaScript hangs in one tab, the other tabs will remain unaffected. The approach is similar to the way Mac OS X isolates applications in their own private areas to prevent one crash from taking down the whole system.

Google picked an interesting way of announcing the project: They commissioned illustrator Scott McCloud to draw a 38-page comic book about the project, and distribute it under a Creative Commons license. The result is a very readable, fascinating way to learn about the new browser.

For web developers, Chrome will include strong Gears integration, and a JavaScript virtual machine that generates super-fast machine code out of JavaScript instructions. For end users, it will include a new start page that lists the last several pages and search terms you've used. It also includes a private browsing mode.

Google is planning on formally launching the project on Wednesday, but the Chrome website isn't visible to the public yet. Update: Google is releasing a version for Windows tomorrow, with Mac and Linux versions coming soon, once Chrome is "faster and more robust." (Thanks, Bryan!)
