IOJones For Mac

According to Apple's developer support website, the I/O Registry is an all-inclusive dynamic database of information about the current hardware device configuration of your Mac, detailing client/provider relationships between active driver objects on the system.

Moreover, some of the entries will automatically change upon connecting new devices to your Mac, which will update the dynamic I/O Registry planes to keep track of hardware changes.

You can go to I/O Registry support page if you want to learn more about all available planes and the architecture of the registry.

IOJones is a free and open source alternative to Apple's IORegistryExplorer application, a tool which has been explicitly designed to help you examine and browse the I/O Registry's multiple planes, displaying all their contents as a tree.

Once launched on your Mac, IOJones enables you to effortlessly browse all I/O Registry planes in both outline and browser modes.

You can rapidly switch between registry planes with the help of the drop-down menu at the top left corner, namely IOService, IOUSB, IODeviceTree, CoreCapture, IO80211Plane, IOACPIPlane, IOFireWire, and IOPower.

You can use IOJones to pinpoint any entry using the search field at the top right corner of the main window and easily create hardware snapshots for later use.

IOJones also provides you with the possibility to sort all tables, as well as open and view previously saved hardware snapshots when needed.

With the help of IOJones, you can swiftly open the Finder location of the kernel extension for the currently selected driver object using the "Reveal Kext in Finder" option in the Go menu, which can also be run via the ⌘+K keyboard shortcut.

Taking all of the above into consideration, IOJones is an excellent alternative to Apple's IORegistryExplorer tool and a fast app for viewing your Mac's dynamic I/O Registry database via a user-friendly and straightforward interface.
