It's possible a system reboot will reset something and the Kext will load. They supply an "Uninstall" application which lands in the Applications directory. In the case of iShowU Audio Capture, there is a rigamarole required to carefully navigate the process.

In my case it is a MacBook Pro and I'm using the trackpad. The earliest suggestion was - make sure I'm doing this with a regular mouse or trackpad, not with a Wacom tablet, nor any other assistive device. Turns out that lots of people are having this issue and for many other applications.

Entering " Some system software was blocked from loading" into DuckDuckGo had some information but no quick fix. The button would turn blue, but nothing would happen beyond this.Īs always the recommendation to learn more is to enter relevant messages into your favorite search engine, like DuckDuckGo. In my case, and the case of many others, clicking on the dang Allow button did nothing. That's a nice and simple user experience. Here's a picture in case that paragraph of text did not make sense. Clicking on the Allow button is supposed to bring up a dialog containing checkboxes, you tick off the checkboxes, click the OK button, and the system allows that Kext to function. In the Security pane will be a message that an application by Such-And-So developer requires permission, and there is an Allow button. Clicking on the dialog is supposed to bring the user to the Security pane in the System Preferences.

In the normal case, when a Kext installation requires permission a dialog is supposed to appear in front of the user. By the way, I'm still uncomfortable typing "macOS" after typing "Mac OS X" for the last 20 years. A "Kext" is a "Kernel Extension", meaning a piece of software that extends the functionality of the macOS Kernel.
