### Describe the Bug

Why does Cursor consume so much memory? What are its system requirements?  
When launched, it consumes 35 GB even before opening the project folder.

### Steps to Reproduce

Launch Cursor. That’s all.

### Expected Behavior

MacOS constantly notifies me that there is insufficient memory for the system to operate.

Hey @Joseph_Gonzales, that sounds problematic - try moving the project folder to a different location and opening it again.

The original location can sometimes trigger high memory usage for a variety of reasons (like a [big chat history](https://forum.cursor.com/t/high-memory-usage-leading-to-ui-freezing-hanging/63846/6)); moving it forces Cursor to treat it as a new project.

Let me know if that helps.

Hey, thanks for the report.

Before we dig in, there’s a known macOS issue where Activity Monitor can show incorrect RAM values. Please verify actual memory usage:

- Open Activity Monitor (native macOS app)
- Go to the Memory tab at the bottom, this shows accurate system-wide memory
- Open the Process Explorer (`Cmd+Shift+P` → “Open Process Explorer”)

Also check:

- Open Cursor with no project loaded, does memory stay high?
- Run `cursor --disable-extensions` from Terminal to rule out extension issues
- Try moving or renaming the project folder, large chat histories can cause memory spikes

Let me know what you find and we’ll continue the investigation!
