What is GLview Extensions Viewer?
GLview Extensions Viewer is a GPU diagnostics utility for inspecting the graphics capabilities of a device. It helps developers, testers, and advanced users check renderer details, supported APIs, and graphics extensions when evaluating compatibility or troubleshooting display and performance issues. On Apple platforms, the app provides information about technologies such as Metal and OpenGL-related capabilities in a native viewer designed for quick reference. It is commonly used when verifying whether a Mac can support specific graphics features, comparing hardware, or collecting technical details for development and support workflows. The app belongs to the GLview product line from Realtechvr, which is focused on graphics capability reporting and benchmarking tools.

Safety overview
Status: Safe
This app is a legitimate graphics information utility. It is generally safe to keep if you use it to inspect GPU capabilities or troubleshoot graphics compatibility. The information it displays is related to your device's graphics hardware and software support, which is normal for this type of tool. If you no longer use graphics diagnostics tools, removing it should only affect your ability to view that hardware information in the app.
Recommendation: Keep GLview Extensions Viewer if you use it for graphics diagnostics, API compatibility checks, or hardware reference. If you installed it for a one-time test and no longer need those tools, you can remove it without affecting normal Mac use.
