A blogger/developer has compiled a very very early build of Google’s browser, Chrome that runs on a Mac. I tested it myself a couple of days ago and it’s fast alright.
It’s so fast that it left most of a browser’s functions at Google’s labs: plug-ins don’t work so it can’t play Flash videos. There’s no History, no Bookmarks, no Preferences, no Find, and you can’t even open a link to a new tab. But it’s fast.
If you want to try Chrome on your Mac, you can download the application at said developer’s blog; the compiled app is for Intel Macs on Leopard only (10.5 and up). Don’t delete your current browser yet because Chrome is sure to have lots of bugs. But it’s fast. Perfect for blog speed-reading.
