For the first time, security experts say, a dangerous form of software called "ransomware" has successfully targeted a Mac operating system, piercing an image of safety that Apple customers had long enjoyed.
The attack, while noteworthy, affected a relatively small number of people and doesn't mean that typical Mac users should panic, experts say.
The software, when installed on a victim's computer, denies a user access to files unless a ransom is paid: about $400. It targets files that users would most likely find important: photos, videos, Excel spreadsheets and Word documents.
