  • The company had previously issued a patch for macOS High Sierra, the most recent version of its Mac operating system, but it put out a new update for High Sierra also.
  • The updates shouldn’t cause the rebooting problems that some PC users experienced after installing similar fixes for Meltdown and Spectre.

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.

Intel on Monday warned users not to install its latest patches for Meltdown and Spectre, because those fixes can cause computers to reboot unexpectedly. However, an Apple representative said these latest updates for macOS and OS X don’t include Intel’s faulty code and shouldn’t trigger the reboot problem.

The Spectre and Meltdown attacks are made possible by an underlying vulnerability related to a feature called speculative execution that’s been used by nearly every computer chip found in PCs, tablets, and smartphones made over the last 20 years. 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.
