Version: 0.51.2 VSCode Version: 1.96.2 OS: Darwin arm64 24.5.0 I installed **C/C++ extension from Anysphere** , and it installs clangd, CodeLLDB and CMake Tools automatically. ![PixPin_2025-06-04_20-27-23](https://us1.discourse-cdn.com/cursor1/original/3X/8/7/871d43c486b19be3efa894f07f1d7c334fc53257.jpeg) However, clangd keep warning about “You have both the Microsoft C++ (cpptools) extension and clangd extension enabled. The Microsoft IntelliSense features conflict with clangd’s code completion, diagnostics etc.” But I have **NO** Microsoft C++ extension on my Mac. ![PixPin_2025-06-04_20-26-28](https://us1.discourse-cdn.com/cursor1/original/3X/0/0/00ee173d40d10e2eee6d5f76350f42b9eee7c561.png) ![PixPin_2025-06-04_20-27-09](https://us1.discourse-cdn.com/cursor1/original/3X/b/5/b5111dfeea9717d4ae846d90a4d6a8049793443c.jpeg) Also, all features that C/C++ IntelliSense provides, including “Go to definition”, “Show call hierarchy”, etc. are **NOT** working properly. What is wrong with Cursor? ---

Hi all – thank you for sharing this issue. We will fix this in the next release for the Anysphere C++ extension. In the meantime, does it work if you click “Never show this warning”? ---

YES, but the other button “Disable IntelliSense” seems not working at all. Anyway, thank you for your reply. I’ll go back to vscode C/C++, and hope Anysphere C/C++ will be a better one! ---

Nope, not now again… ms-vscode.cpptools is removed from extensions library again. and the intellisense is broken again with both tools… Any more updates? ---

Hi @Jingxian\_■■■■, unfortunately that extension isn’t available in the extension marketplace. The Anysphere C/C++ extension relies on ClangD for the language server, which needs to be configured via a `compile_commands.json` (the build tool, such as CMake, can generate this file). Please see [Intellisense disabled in new C++ extension](https://forum.cursor.com/t/intellisense-disabled-in-new-c-extension/98437) for more on configuring ClangD. ---
