You should apply this fix as soon as you can if you’re running Apple’s latest desktop OS.
Apple has issued a statement on the patch. It apologized for the flaw, noting that “customers deserve better,” and is reviewing its “development processes” to prevent a repeat. Also, you’ll soon have this update as a matter of course: Apple will automatically install it on all systems running macOS 10.13.1 sometime later today. You can read the full statement below.
“Security is a top priority for every Apple product, and regrettably we stumbled with this release of macOS.
“When our security engineers became aware of the issue Tuesday afternoon, we immediately began working on an update that closes the security hole. This morning, as of 8 a.m., the update is available for download, and starting later today it will be automatically installed on all systems running the latest version (10.13.1) of macOS High Sierra.
“We greatly regret this error and we apologize to all Mac users, both for releasing with this vulnerability and for the concern it has caused. Our customers deserve better. We are auditing our development processes to help prevent this from happening again.”
