Apple releases Meltdown patches for older versions of Mac

At any rate, in order to keep your system secure, you'll need to install these latest patch updates. Microsoft has consigned numerous Windows versions to the bone orchard given that updates to older devices can bork legacy software.

Apple on Tuesday issued updates for macOS Sierra and OS X El Capitan, the two versions of its computer operating system that preceded macOS High Sierra, which the company released last fall. It also fixes an issue with an SMB server. And the company also dropped a number of software updates overnight that patch older versions of macOS/OS X against Spectre and Meltdown as well as addressing other problems right across their full suite of operating systems.

Security Update 2018-001, as the patch is called, mitigates the dangers of Meltdown and Spectre. The attacks, which became public earlier this month, could allow a malicious actor to exploit that vulnerability and get access to the secret data that's on a computer, including passwords. The update means more Mac users will be safe from a vulnerability that affects hundreds of millions of chips made by Intel over the past twenty years.

macOS High Sierra is going even higher today with the first developer beta version of macOS 10.13.4 now available. Those running macOS Sierra should look for version 10.12.6.

Other noteworthy bugs include CVE-2018-4094, a bug in both Sierra and High Sierra discovered by five researchers at Yonsei University in Seoul, South Korea.

The move brings Apple closer to being on par with Microsoft in terms of deploying protections for older versions of its desktop operating systems.

That said, we can't be certain.
