With a focus on improving compatibility with the MacBook Pro with Retina Display, Global Delight has released Voila 3.3, addressing a number of bugs specific to Retina display screenshots in the screen capture utility. Also fixed are crashes related to multiple monitor setups and a video corruption problem on the MacBook Air. For those with the MacBook Pro with Retina Display, note that you can set different export formats in Voila’s Export preferences; that way you can easily export more-compact formats when the Retina display screenshots are too large for email or a blog post. ($29.99 new from Global Delight — with a 25% discount for TidBITS members — or the Mac App Store, free update, 13.8 MB, release notes)
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.
