Approve System Extension

In macOS High Sierra (10.13) and later, you must now explicitly approve installation of a System Extension inside of System Preferences.

Our Trim Enabler feature comes in the form of a custom System Extension, which has been signed and notarized according to Apple's latest security requirements. However, upon the first installation, you will be required to approve it manually by following the instructions.

Apple Certificates are distributed per individual, except for giant corporations with enterprise accounts. Oskar Groth is the founder and developer behind all Cindori apps.

I'm unable to select the Allow button

If the "Allow" button is not selectable, make sure to click the lower-left Lock button in System Prefences and authenticate yourself as an administrator.
