Many OpenGL extensions, as well as extensions to related APIs like GLU, GLX, and WGL, have been defined by vendors and groups of vendors. The extension registry is maintained by SGI and contains specifications for all known extensions, written as modifications to the appropriate specification documents.

The registry also defines naming conventions, guidelines for creating new extensions and writing suitable extension specifications, and other related documentation.

This program displays the vendor name, the version implemented, the renderer name and the extensions of the current OpenGL 3D accelerator.

Supports OpenGL 1.1 to 2.1 and OpenGL 4.2 or superior for OSX 10.7 and superior, including Apple Metal information.

Customer Reviews

It works now! I just wish it worked better.


I figure I need to write a new review, because the latest version (4.0.8) actually works for me! Great update.

Now, the app itself: there's a lot of data here, but it's not the easiest to use. For example, at the bottom of the "Extensions" tab, there's a round search box, like you'd normally find at the top of a window. Typing in there searches the list of extensions, but it's pretty slow. There's also a (misaligned) "Search" button next to this, and when I click it, it switches to my web browser and seems to open a new tab for each extension shown in the list (in my case, about 100). Yikes! I did not expect that. This is not an isolated case: I found myself saying "I did not expect that" a lot.

The screenshots show OS X 10.6, and that's probably what it was tested against. Not everything looks so great on 10.7+. For example, you can only see 2 pixels width of the scrollbars on the "Extensions" tab. Nothing is completely broken, but it does seem somewhat unfinished.

If you can figure out how to use it, there's a fantastic amount of data in here. Unfortunately, it's not very intuitive, and the documentation is almost nonexistant.

Cannot uninstall or remove this software


This software was installed my accident on my Macbook Pro, and is now impossible to remove. Every time I drag this app from the Applications folder to the Trash and empty the Trash, it replaces itself with another copy. It also always needs to update. I have installed version 4.25 at least 30 times now. Every time I turn on my computer, I get a push notification from the App Store stating that the “update installed successfully”, even after I have removed this app from my machine. The developers have not responded to my emails asking for further assistence to remove this application, so the only conclusion I can come to is that this app is a piece of malware that cannot ever be uninstalled. 0/10 - would not recommend.

Terrific Tool


Apple has a fantastic OpenGL implementation and this is a terrific way to compare features of graphics cards. In theory, I should be able to compare the features between Intel HD Graphics and the NVidia chip in the Retina MBP, but not sure why Intel is not listed. Still, I'm really new to the Retina model...
