Apple has released MacBook Pro (Retina, 13-inch, Late 2013) Software Update 1.0, which affects only those who have purchased one of the just-released models (see “New Retina MacBook Pro Models Thinner, Lighter, and Cheaper,” 22 October 2013). However, as this update solely replaces the missing Simplified Chinese and Traditional Chinese OS X Software License Agreement with a fresh copy in your Documentation folder, you can probably skip this one, particularly if you’re not using either of these localizations.

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.
