Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Environment:

  • Cursor 3.3.30
  • macOS 26.4.1 (25E253)
  • MacBook Pro, Apple M5 Pro

What happens:
Cursor launches, runs for ~20–30 seconds, then the renderer process crashes with reason: 'crashed', code: '5'. It restarts and crashes again faster each time.

From main.log:

CodeWindow: renderer process gone (reason: crashed, code: 5)
CodeWindow: detected unresponsive
Error: Render frame was disposed before WebFrameMain could be accessed

What I’ve tried:

  • Cleared GPU cache, shader cache, all caches
  • Clean reinstall
  • disable-hardware-acceleration: true in argv.json
  • Multiple flags: disable-gpu, disable-gpu-compositing
  • None of these help

Root cause (likely):
A process sample shows Cursor is loading AGXMetalG17X (the M5 Pro GPU driver, new in macOS 26). Electron 39 almost certainly has never been tested against this driver. The renderer subprocess is being killed — macOS crash reports aren’t even generated, suggesting the OS is terminating it rather than it crashing itself.

Request:
Please update Electron to a version with macOS 26 / M5 Pro support, or add a fallback rendering path when AGXMetalG17X is detected. Cursor is completely unusable on this hardware+OS combination.

Happy to provide any additional diagnostics.
