Apple has released OS X Mountain Lion 10.8.5 Supplemental Update with a couple of sleep-related fixes, including a bug that could cause external drives to be ejected after your Mac goes to sleep and a problem that prevented HDMI audio from working after wake from sleep. The supplemental update also fixes an issue that prevented some applications from accessing the FaceTime HD camera on mid-2013 MacBook Air models and a bug with USB Bluetooth adapters. It’s available as a direct download from Apple’s Support Downloads Web page or via the Mac App Store. (Free update, 18.7 MB)
Springy Dock Tricks
If you drag a file and hover over Dock icons, various useful things happen which are similar to Finder springing. If it's a window, the window un-minimizes from the Dock. If it's a stack, the corresponding folder in the Finder opens. If it's the Finder, it brings the Finder to the foreground and opens a window if one doesn't exist already. But the coolest (and most hidden) springing trick is if you hover over an application and press the Space bar, the application comes to the foreground. This is great for things like grabbing a file from somewhere to drop into a Mail composition window that's otherwise hidden. Grab the file you want, hover over the Mail icon, press the Space bar, and Mail comes to the front for you to drop the file into the compose window. Be sure that Spring-Loaded Folders and Windows is enabled in the Finder Preferences window.
