Cursor "No ptyHost heartbeat after 6 seconds" Bug Report

Bug Reports
11

I had the same error on MacOS ARM versions 0.43.0 and on, and just today miraculously discovered something that worked for me.[1] Simply locate the file ptyHostMain.js in the application bundle and add the following line to the top:

process.on('SIGTERM', () => {});

For me, this was: /Applications/Cursor.app/Contents/Resources/app/out/vs/platform/terminal/node/ptyHostMain.js. In my case, analyzing Cursor’s logs revealed that the ptyHost process kept getting killed with code 15 (SIGTERM).
