Apple has released a Meltdown patch for MacOS users. The patch was released on Tuesday and has been rolling out to all of its users. It currently applies for macOS Sierra and OS X El Capitan users, the two operating systems Apple released in September 2016 and September 2015, respectively. The latest version of macOS, that is High Sierra, had been patched earlier this month.

Apple claims the update fixes some serious security vulnerabilities and also patches an issue that could lead to arbitrary code execution when playing a malicious sound file.

The Meltdown issue was discovered about a year ago, but only disclosed to the public recently. The issue affects processors from Intel, AMD and more, with Intel being in the limelight. It was originally suggested that Intel processors are the only ones vulnerable, but others are affected too. In addition, Meltdown affects Intel processors going back almost a decade, making this a very serious security issue. 

The patch currently applies for macOS Sierra and OS X El Capitan users.

The iPhone maker claims that the update fixes some serious security vulnerabilities and likewise patches an issue that could lead to arbitrary code execution when playing a malicious sound file.

Intel had earlier sent out a patch for its chips, though the company later told users to not use the patch just yet. Intel said the patch was causing Broadwell and Haswell chips to face “higher system reboots”, which Intel meant to solve with future updates.
