Apple's Legacy System Extension warning

Recommended Posts

Today, Apple released macOS 10.15.4, which adds a new warning when kernel extensions are installed:


More information from Apple can be found here:


We are aware of this, and have been working on replacing our kernel extension since late last year. We plan to replace it with Apple's new EndpointSecurity framework before the release of macOS 10.16, when it is assumed that kernel extensions will no longer work, in part or in full. (We only know that Apple has said they "will not work without compromise" in "a future version of macOS." But we'd rather not find out the hard way exactly what that means.)

The kernel extension will continue to be supported for macOS 10.14 (Mojave) and earlier, but macOS 10.15 (and later) will no longer need it, once we have an update available.

So, no need to panic. We've still got your back, and won't let your protection falter. All you've got to do is make sure you're keeping Malwarebytes for Mac up-to-date. If you have updated to at least version 4.2, and have not disabled the new auto-update feature, it'll update itself in the background without you needing to do anything. To ensure you're up-to-date, just open Malwarebytes and choose Check for Updates from the Malwarebytes menu.
