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)
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the best-selling Take Control ebooks.
