What version of the Codex App are you using (From “About Codex” dialog)?

What issue are you seeing?

I’ve noticed higher memory usage from the Codex Mac app after updating to the latest version, and I’m trying to figure out if this is expected or a bug.

After launching Codex, it loads normally but then gradually starts using a lot of memory over time. Before the recent update, the app used noticeably less memory on the same machine.

Setup:

MacBook Air M2 15 ( 8gb)

Latest macOS (macOS Tahoe 26.4.1)

Latest Codex app ( Codex 26.422.21637)

Is anyone else seeing increased memory usage with the latest Codex release on macOS, or is it just my setup?

What steps can reproduce the bug?

Open the Codex desktop app on macOS. Start a normal coding session Leave Codex open in the background while working. You can observe increased memory usage compared to previous versions.

What is the expected behavior?

I expect the Codex app’s memory usage to stabilize at a reasonable level during normal use and not keep growing over time when the app is mostly idle.

Ideally, memory usage should be similar to or lower than previous versions on the same machine and workloads

Additional information

The memory increase happens even if I only have one project open.

TL;DR

The increased memory usage in the Codex Mac app after updating to version 26.422.21637 may be a bug, and reporting this issue to the Codex support team with detailed system and usage information could help resolve the problem.

Guidance

  • Verify that the issue persists across different projects and workloads to rule out project-specific causes.
  • Monitor system resources and Codex app memory usage over time to identify any patterns or correlations with specific app features or actions.
  • Check if other users with similar setups (MacBook Air M2 15, macOS Tahoe 26.4.1, and Codex 26.422.21637) are experiencing similar issues to determine if it's an isolated problem.
  • Consider providing more detailed system specifications, such as available RAM and disk space, to help the support team investigate the issue.

Notes

The provided information suggests a potential bug in the latest Codex app version, but more data and testing are needed to confirm this. The issue may be specific to certain system configurations or usage patterns.

Recommendation

Apply workaround: Report the issue to the Codex support team with detailed system and usage information, as they may be able to provide a patch or temporary fix for the problem.
