Mac os ( macOS Tahoe 26.4.1 )
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.
