A blog of tips, tricks, hints and hacks for Mac OS X, like those printed in the excellent Mac Kung Fu 2nd Edition*. You'll also find tips for the iPhone and iPad (iOS).
To get onto the blog (and into the book) the stuff written about here has to:
1. Be non-obvious (making use of features that are hidden, obfuscated, secret, experimental etc);
2. Make the most of OS X's built-in tools (i.e. no recommendations for apps costing $$, although occasional recommendations of freeware apps might be made to fill a deficiency in OS X's feature set).
This blog is updated almost regularly by Keir Thomas, an award-winning author who's written a handful of computing books, edited several national computer magazines in the UK (and contributed to countless others), and blogged professionally for various IDG sites, including PC World and Macworld. He's also written a novel and created a diet plan for geeks.
