In our sneak peak at the new Google Desktop for Mac, Scott wondered at Google's use of a proprietary installer. Like many Mac users, I get annoyed at installers, though I understand that sometimes they are necessary. Similarly concerned, John Gruber at Daring Fireball performed a test install and then did a file level comparison of his system before and after. As Gruber notes: "This matters with Google Desktop, because there are a lot of files, and they're installed into some interesting - if not suspicious - locations." This includes an Input Manager and some possibly questionable kernel extensions (which are likely necessary to make the full system-wide search possible). I should be clear: nobody is accusing Google of doing anything underhanded, but if you like to know exactly what's going on with your system, John's article is worth a read before installing Google Desktop.
