On Wednesday, the company patched the Sierra and El Capitan operating systems against the Meltdown security flaw.

Apple recently rolled out the final version of macOS High Sierra 10.3.3 for all compatible Mac models.

Together with last week's update, this means the last three major revisions of macOS are not protected from the processor bugs. According to the update's release notes, it "Addresses an issue that could cause Messages conversations to temporarily be listed out of order" and "Resolves an issue that could cause your Mac to stop responding when connected to an SMB server". These updates include patches for the Meltdown bug that emerged earlier this month. It also patches an issue that could lead to arbitrary code execution when playing a malicious sound file.

You can download the update through the Mac App Store.

You want to stay safe from hackers while still using an older version of Apple's MacOS - the underlying software that runs MacBook computers.
