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
Copy Existing Filename to 'Save As' Field
While many utilities provide file naming automation, they're mostly overkill for those cases when you need to make small variations in file content while ensuring the documents group together in a "by name" list.
In the Save As dialog, the default name is the current document name. You can quickly change this to match any existing file.
1. Make the list of files the active element.
2. Click on a grayed-out filename, which momentarily turns black.
3. The Save As field now contains the filename you just clicked.
You can modify the name (adding, say, "version 3") or overwrite that existing file you clicked.
