What issue are you seeing?

The bundled "Computer Use" component crashes every time Codex tries to initialize it on my machine.

My system is macOS 13.6.2, and the crashing helper process is:

• SkyComputerUseClient
• Bundle identifier: com.openai.sky.CUAService.cli
• Version: 1.0 (755)

The crash happens at launch, before the helper can start normally. The key error is:

Termination Reason: Namespace DYLD, Code 1 Library missing
Library not loaded: /usr/lib/swift/libswiftObservation.dylib
Referenced from: /Users/USER/*/Codex Computer Use.app/Contents/SharedSupport/SkyComputerUseClient.app/Contents/MacOS/SkyComputerUseClient
Reason: tried: '/usr/lib/swift/libswiftObservation.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/libswiftObservation.dylib' (no such file), '/usr/lib/swift/libswiftObservation.dylib' (no such file, not in dyld cache)

The crash report also explicitly says:
"built for macOS 15.0 which is newer than running OS"

This now happens consistently whenever Codex attempts to use or initialize the Computer Use feature.

What steps can reproduce the bug?

1. Use Codex App 26.417.41555 (build 1858) on macOS 13.6.2.
2. Leave the bundled "Computer Use" feature enabled.
3. Launch Codex and trigger any flow that initializes Computer Use, or let Codex initialize it automatically.
4. Codex starts SkyComputerUseClient.
5. SkyComputerUseClient immediately crashes with a DYLD library-missing error.

Notes:

• This is reproducible every time on this machine.
• No special prompt is required if Computer Use is initialized automatically.
• Session id / token limit / context window: not applicable, because this is a local helper startup / OS compatibility issue rather than a model-session issue.

What is the expected behavior?

Codex should not ship or auto-update a Computer Use helper that requires a newer macOS version than the one supported by the current machine.

Expected behavior would be one of the following:

• Computer Use should work on macOS 13.6.2 if this OS version is supposed to be supported, or
• the feature should be disabled automatically on unsupported macOS versions, with a clear compatibility message in the UI, or
• Codex should avoid launching the helper at all on unsupported systems instead of repeatedly crashing at startup.

Additional information

Additional diagnostic details:

• Main Codex app version: 26.417.41555 (build 1858)
• macOS version: 13.6.2 (22G320)
• The main Codex.app appears to support older macOS versions, but the bundled Computer Use helper does not.
• The bundled Codex Computer Use.app and SkyComputerUseClient.app both declare LSMinimumSystemVersion = 15.0.
• The SkyComputerUseClient binary also reports LC_BUILD_VERSION minos 15.0.
• The crashing Computer Use bundle version is 1.0.755.
• This looks like a packaging or rollout compatibility issue specific to the Computer Use plugin/helper rather than the main Codex app.

Temporary workaround:
I plan to disable the Computer Use feature in Codex settings so the helper is not launched on this machine.
