macOS 10.15.4 to Warn About Deprecated KPIs

Apple:

At WWDC19, we announced the deprecation of kernel extensions as part of our ongoing effort to modernize the platform, improve security and reliability, and enable more user-friendly distribution methods. Kernel programming interfaces (KPIs) will be deprecated as alternatives become available, and future OS releases will no longer load kernel extensions that use deprecated KPIs by default.

[…]

Below is a list of deprecated KPIs as of macOS 10.15. In macOS 10.15.4, use of deprecated KPIs triggers a notification to the user that the software includes a deprecated API and asks the user to contact the developer for alternatives.

Via Howard Oakley:

Normally, this requires you to run the app (or its installer), during which it and macOS should prompt you to open the General tab of the Security & Privacy pane, authenticate, and agree to the kernel extension being installed. This consent is only available for a relatively short time: if it occurs when you’re out, it’s possible that it will vanish, and you may have to repeat the process to catch it. This is what Apple calls User-Approved Kernel Extension Loading, and doesn’t involve the Privacy tab, with which you’re probably now more familiar.

[…]

Sometimes, even after closing the app or installer and restarting, the kernel extension doesn’t get installed properly. You can repeat the process, maybe even a couple of times, restarting after each attempt. But in some cases – in Macs with a T2 chip only – the kernel extension won’t load properly unless you disable Secure Boot.
