A beta version of FaceTime for Mac is now available from Apple. You can use your Mac to make FaceTime calls to other Mac, iPhone, iPad, and other iOS device users.
FaceTime for Mac beta was announced at the 'Back to Mac' event this week, but the download link wasn't available right away.
Keep in mind that beta versions of software usually have their share of bugs and problems. Two security issues have already been discovered.
FaceTime for Mac Beta Security Issues
The FaceTime Account settings within the application can display your private account information to anyone who has physical access to your Mac.
To compound the problem, FaceTime for Mac beta retains your account name and password, so anyone who has access to your Mac can sign back in to FaceTime and access the private data that the first security issue exposed.
These and other concerns will be addressed before FaceTime for Mac goes golden (final release). In the meantime, you can protect your account information by making sure your Mac account is password protected, and not set to automatically log you on. Be sure to log out or shut down if you leave your Mac unattended.
