IORegistryExplorer for Mac is a lightweight system utility that allows macOS users to browse their IO registry utilizing streamlined GUI interface. Since Mac has a dynamic I/O registry database that keeps all the information about currently detected hardware and services in real time, Mac users don’t have any system utility to properly track the changes in that database. It changes that and provides a simple way to explore the entirety of that database whenever you want.
In addition of connecting to the I/O database and providing several ways of formatting the database entries, It also has a built-in search function, enabling you to easily search for desired names, classes, bundle identifiers, property keys and values, states, inheritance values and more. In addition to viewing the entire database, you can also search in individual planes.

No matter if you are novice or seasoned professional, It provides valuable service by connecting to I/O Registry database using easy to use visual layout and straightforward browsing capabilities. Advanced users can also take advantage of features such as bookmark and search tool. IORegistryExplorer for macOS updates the registry in real time, but the refresh period can be manually set to a specific interval of your choosing.
