A vulnerability in iOS 6 and OS X 10.8 Mountain Lion can crash apps and even render them unusable if certain strings of text are rendered. The text strings can cause Messages and Safari to crash, and can cause additional errors if a Wi-Fi network is named with the text. The problem is reportedly fixed in the betas of iOS 7 and OS X 10.9 Mavericks, but we expect Apple to address it in iOS 6 and Mountain Lion updates as well. follow link
Increase Boom Volume Quickly
If you're using Boom to increase the volume on your Mac, you can change the amount to which Boom increases the volume quickly in two ways. Either use the slider available from Boom's menu bar icon, or enable and set hotkeys (Command-Shift-+ and Command-Shift-- by default). Then, when you need that push to 11, more volume is available at the click of the mouse or tap of the keyboard.
