More news about patches for the Spectre/Meltdown bugs that have left just about every device out there with a security hole thanks to a flaw in nearly all processors.

Apple has issued a fix for older Macs running the latest versions of macOS Sierra (10.12.6), and OS X El Capitan (10.11.6). Their earlier fix was only for devices running macOS 10.13.2.

So, if you’re running those operating system, open the app store and look for updates. If you see one available, select Update.

Also on the Spectre/Meltdown front, Intel believes it’s found out what’s causing devices with Haswell and Broadwell chips to suddenly reboot. They’ve asked manufacturers to stop distributing the firmware patches for the problem until they can fix it.

Here’s what the company said in a statement:

“We recommend that OEMs, cloud service providers, system manufacturers, software vendors, and end users stop deployment of current versions, as they may introduce higher than expected reboots and other unpredictable system behavior.”

Intel is working to fix the problem.

Microsoft has fixed the patch that was making some computer running AMD chips unbootable. Users should be able to apply the latest security updates without issue.
