Developer Panic has decided to not sell version 2.5 of its Apple Design Award-winning Coda Web development app in the Mac App Store, citing the difficulty of working with Apple’s sandboxing requirements. Apple began requiring apps submitted to, or updated on, the Mac App Store to be sandboxed as of 1 June 2012, forcing many developers to pull their apps from the store, stop updating them, or remove features to comply with the requirements. 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.
