Apple released an update to the OS X 10.8 Mountain Lion Preview 4 yesterday afternoon. The system will now do daily checks for security updates and will install them automatically or upon restarting your Mac.
This shows Apple’s growing concern about malware attacks on the Mac platform, particularly after the Flashback attack earlier this year. The system also includes a more secure connection to Apple’s update servers.
Apple says that any developers who have downloaded and installed the Mountain Lion Developer Preview 4 should install this update as soon as possible.
Mountain Lion should be available next month in the Mac App Store for $19.99.
