On the weekend Google released its Gears technology to the Safari browser on Mac OS X. You may still have to click on the "Mac" platform link if the Gears' platform test script still claims that your Safari browser is not supported. Alternatively you can go directly to the Gears Macintosh platform .dmg download.
For those who does not know what Gears is you can check out Gears' FAQ page. In short it enables web developers to create offline versions/components of their web applications.
Like with most things that Google does, Gears is opensource. Although this is true I am still trying to figure out why one would code to Gears rather than the more Standards compliant HTML5? If anyone like to share their thoughts, please submit a comment below.
