The 1.1 version of KextViewr for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Design & Photo Tools, more precisely Viewers & Editors. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free Mac app is a product of objective-see llc.
From the developer:
KextViewr helps you to view all modules on that are loaded in the OS kernel. Modules that are loaded into the kernel are called kernel extension, or 'kexts.' They run at the OS's highest privilege level; ring-0. KextViewr displays all loaded kexts, along with their signing status, full path, VirusTotal detection ratios, and more!
You may want to check out more software for Mac, such as Morph Age, Photo Mechanic or MozoDojo, which might be similar to KextViewr.
