Cursor 2.4.x instability: agent command failures, stalls, and plan-mode popups
Multiple recent reports indicate Cursor 2.4.35–2.4.37 have agent command execution failures, stalls, and plan-mode file refresh loops on macOS and Linux. On macOS (2.4.37), users report the agent cannot run any commands in IDE or CLI; a staff response flags a known sandbox issue and suggests switching Agents > Auto-Run Mode to “Ask Every Time” to disable sandbox as a workaround ([thread](https://forum.cursor.com/t/in-the-cursor-ide-and-cli-when-the-agent-tries-to-run-a-command-all-commands-fail/152020)). On Linux (2.4.35 AppImage), plan tabs repeatedly reopen with “The content of the file is newer” prompts, copy actions fail during generation, navigation lags, and the window crashes (code 132) when GPT-5.2 is running ([thread](https://forum.cursor.com/t/dozend-of-plans-reopen-at-once-with-the-content-of-the-file-is-newer/152041)). Related posts describe agents stalling/getting stuck and ignoring iteration rules, suggesting broader instability across the 2.4.x line ([stalls](https://forum.cursor.com/t/cursor-agent-stalls-gets-stuck/152008), [iteration rules](https://forum.cursor.com/t/cursor-is-ignoring-even-the-most-simple-rules-in-iteration-development-approach/152025), [tag change question](https://forum.cursor.com/t/what-the-think-tag-in-cursor-version-2-5-14-has-been-changed-to/152026)).
