Security researchers identify new bugs that can give remote Mac access to hackers.
Apple has rolled out its first automated security update to Macintosh computers, to protect the systems from newly identified bugs such as CVE-2014-9295.
Laptops and desktops will be automatically updated without requiring user permission.
Department of Homeland Security and the Carnegie Mellon University Software Engineering Institute found new bugs, which could give remote access of the systems to hackers.
Reuters quoted Apple spokesman Bill Evans as saying that the automated security software has been rolled out to rectify vulnerabilities in the network time protocol (NTP), which is a part of OS X and synchronizes clocks on the systems.
Carnegie Mellon identified several other companies whose products could be vulnerable to security threats.
The previously released security patches by Apple required user permission.
Although Apple claims to have developed the automated technology two years ago, it is only now releasing the technology due to the severity of the vulnerabilities.
Evans said that the update is seamless and would not even require the users to restart their systems.
