Macs Fan Control for High Sierra 10.13: A Step-by-Step Guide

When it comes to installing Universal Control (UC) on Macs running macOS High Sierra 10.13, you may encounter some challenges due to Apple's heightened security restrictions. In this article, we'll walk you through the process of installing UC 1.7.6 or UC 2.x releases not already installed on your system.

Upon installation, you'll likely see a blue OK button by default. However, clicking this button won't install the driver. Instead, click 'Open Security Preferences' to proceed with the installation.

The first screen you'll encounter after installing UC will indicate that Apple's security restrictions have blocked our Kernel Extension (KEXT), which is necessary for PreSonus devices to function correctly. To overcome this issue, you'll need to navigate through some additional screens and approve the KEXT load request.

It's essential to note that approval is automatically granted to third-party KEXTs that were already present on your system when upgrading to macOS High Sierra 10.13. However, when a request is made to load a KEXT that you haven't yet approved, the load request will be denied.

As stated in Apple's Technical Note TN-2459, 'macOS High Sierra 10.13 introduces a new feature that requires user approval before loading newly-installed third-party kernel extensions (KEXTs).' This means that apps or installers that treat a KEXT load failure as a hard error will need to be changed to handle this new case.

To get older installs of Universal Control working correctly, you may need to go through a reboot or two and check off some boxes along the way. With careful navigation, you should be able to install your PreSonus devices successfully.

In summary, installing UC on Macs running macOS High Sierra 10.13 requires some additional steps due to Apple's security restrictions. By following these instructions and understanding the new KEXT load approval process, you'll be able to get your PreSonus devices up and running smoothly.
