What issue are you seeing?

Computer Use stopped working after the bundled plugin was updated from
1.0.799 to 1.0.1000366.

Environment

• Codex App: 26.707.31428
• Computer Use plugin: 1.0.1000366
• Computer Use native service: 26.708.1000366
• macOS: 15.7.4 (24G517)
• Device: MacBook Pro (MacBookPro17,1)
• Chip: Apple M1

Steps to reproduce

1. Open Codex Desktop on macOS 15.7.4.
2. Install or enable the bundled Computer Use plugin.
3. Start a task that invokes Computer Use.
4. Call list_apps or get_app_state.

Actual result

Computer Use fails with:

Sky Computer Use native pipe startup failed
The underlying error is:
Sky Computer Use native pipe is unavailable:
native pipe path unavailable:
No such file or directory (os error 2)
The native service crashes immediately at launch. The macOS crash report
contains:
Exception: EXC_CRASH (SIGABRT)
Termination namespace: DYLD
Indicator: Symbol missing

Symbol not found:
_swift_task_addPriorityEscalationHandler

Referenced from:
Codex Computer Use.app/Contents/MacOS/SkyComputerUseService

Expected in:
/usr/lib/swift/libswift_Concurrency.dylib
SkyComputerUseClient crashes with the same missing symbol.
The service declares macOS 14.4 as its minimum deployment target, but it was
built with SDK 26.4 and references a Swift runtime symbol unavailable on
macOS 15.7.4.
Because the service crashes before initialization, this socket is never
created:
~/Library/Group Containers/
2DC432GLL2.com.openai.sky.CUAService/IPC/computeruse.sock
Reinstalling the Computer Use plugin, restarting Codex, and restarting the
computer did not resolve the issue.
The previous Computer Use plugin version 1.0.799 worked on the same computer
and macOS installation.
Expected result
Computer Use should launch on every macOS version declared as supported.
The native service should either avoid the unavailable Swift 6.2 API, bundle
a compatible runtime, or declare macOS 26 as its actual minimum requirement.

### What steps can reproduce the bug?

1. Run Codex Desktop 26.707.31428 on macOS 15.7.4.
2. Install or enable the bundled Computer Use plugin version 1.0.1000366.
3. Start a Codex task and invoke the Computer Use skill.
4. Call any Computer Use API, such as `list_apps` or `get_app_state`.
5. Observe that Computer Use fails with `Sky Computer Use native pipe startup failed`.
6. Check the macOS crash report and observe that `SkyComputerUseService` was terminated by DYLD because `_swift_task_addPriorityEscalationHandler` is missing.
