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
Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.
