What is Cursor on Mac?
By Junaid, maker of Taskglass · Last reviewed
The Cursor AI code editor (based on VS Code) and its helper processes.
Cursor is an AI-focused code editor built on VS Code, so it uses the same Electron process layout: Renderer helpers draw windows, Plugin helpers run extensions and language tools, and the GPU helper handles graphics. Indexing your codebase for AI features can also use CPU after opening a project.

- Indexing a codebase for AI features
- Extensions and language servers working on a big project
- Many windows or large files open
- File watching in folders with huge numbers of files
What to do

- 2Use Help > Open Process Explorer to see which part is busy
- 3Disable heavy extensions and exclude big folders from watching
- 4Restart Cursor
Safe to quit? Yes.
Safe to quit the app; save your files first. Quitting a single helper can crash a window.
