Ars Technica summarize a problem with an App Store server that generated faulty DRM code for several days, causing downloaded Mac and iOS apps to crash on launch and users to hit developers with angry 1-star reviews. Apple has fixed the problem, which affected at least 120 apps and tens of thousands of users who downloaded updates or new apps during the time the problem occurred. Apple also reset the version numbers of affected apps to conceal (but not remove) the angry 1-star reviews. If you downloaded any apps around 5 July 2012, it’s worth checking for updates again. follow link
New Documents in Snow Leopard's TextEdit
In the Snow Leopard version of TextEdit, you can now create a new document by Control-clicking TextEdit's Dock icon (when it's running), and choosing New Document from the pop-up menu. This isn't a major feature, of course, since you can also just press Command-N while in TextEdit, but consider Control-clicking other applications' Dock icons to see what functions they might make available.
