Apple on Tuesday rolled out OS X El Capitan v10.11.3 for its desktop users. The new update offers bug fixes and squashes numerous security holes. It is available to download via the Updates tab inside the Mac App Store.
The OS X El Capitan v10.11.3 update fixes multiple security holes, eight of which could have been exploited by attackers to execute arbitrary code. The Cupertino-based company added that it has also patched a vulnerability that allowed a quarantined application to override OSA script libraries installed by the user.
In addition to security patches, OS X El Capitan v10.11.3 also fixes an issue that prevented some Mac computers from waking from sleep. The issue affected users who were connecting their Mac computers to certain 4K displays.
On the sidelines, Safari has also received a security-centric update. Available for OS X Mavericks v10.9.5, OS X Yosemite v10.10.5, OS X El Capitan v10.11 to v10.11.2, the update fixes a vulnerability that exposed users to attacks when visiting a malicious website. There's also a fix for WebKit CSS that allowed a website to know if a user had visited a certain link.
In addition, OS X El Capitan v10.11.3 also offers a fix when "third-party .pkg file receipts stored in /var/db/receipts are now retained when upgrading from OS X Yosemite."
As for what to expect from the future updates, the recently released OS X El Capitan v10.11.4 beta offered a feature dubbed NumberSync that bridges a mobile phone number to Mac. Apple is also working on bringing password protected to Notes, and Live Photos is coming to the Messages app.
