Input method not recognized on macOS 27.0 — CodeWhisperer does not appear in Input Sources

The issue is with the CodeWhisperer input method registration on macOS 27.0. Start by examining the input method installation and registration code, likely in the CLI's integration or helper modules. Look for the symlink creation logic and the input method bundle's Info.plist. Check macOS input method APIs and compatibility with the new OS version. Verify the bundle is correctly signed and structured. Testing requires a macOS 27.0 environment to reproduce the registration failure.

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 27.0.0 (26A428)

Expected behaviour

Description

On macOS 27.0, kiro-cli doctor reports "Input method is not running",
and the input method cannot be enabled because it never appears
in System Settings > Keyboard > Input Sources.

Environment

• macOS: 27.0 (Build 26A428)
• Terminal: Ghostty
• kiro-cli version: 2.24.0

Doctor output

✘ Input Method: Input method is not running
Attempting to fix automatically...
Re-running check...
✘ Input Method: Input method is not running

Steps tried

1. Ran kiro-cli integrations install input-method.
   System Settings > Keyboard opens, but no Kiro / CodeWhisperer
   input source is available to add.
2. Verified the symlink exists and points to a valid path:
   ~/Library/Input Methods/CodeWhispererInputMethod.app
   -> /Applications/Kiro CLI.app/Contents/Helpers/CodeWhispererInputMethod.app
   The target exists (contains Contents).
3. Logged out and logged back in.
4. Checked Input Sources > "+" > "Others":
   CodeWhisperer is still not listed.

Expected behavior

CodeWhisperer input method appears in Input Sources and
kiro-cli doctor passes.

Actual behavior

The input method is never registered by macOS,
so autocomplete cannot work.

Notes

All files appear to be in place, so this looks like a
compatibility issue with macOS 27's input method registration.

Actual behaviour

kiro-cli doctor
