Pull request overview
Backport of #27486 to release/v7.6.3. Adds a verification step after ESRP signing in the macOS sign jobs to detect silent no-ops by checking that signed Mach-O binaries contain the expected Developer ID Application signature string, failing the signing job rather than discovering the issue later in packaging.
Changes:
- Adds a PowerShell verification step in
Sign_macOS_*jobs that scanspwshand*.dylibfiles for the expected Developer ID signature string and throws if missing.

Impact
REQUIRED: Choose either Tooling Impact or Customer Impact (or both). At least one checkbox must be selected.
Tooling Impact
Adds
codesign --verify --deep --strictverification immediately after ESRP signing inSign_macOS_*pipeline jobs. This ensures silent ESRP no-ops are caught in the signing job itself rather than discovered later in packaging, preventing publication of bad signed artifacts.Customer Impact
Regression
REQUIRED: Check exactly one box.
This is not a regression.
Testing
Verified by next pipeline run. This is a pipeline YAML-only change adding a defensive verification step — no unit tests apply. The original change was validated during a release build where ESRP silently no-op'd; this check would have caught it at the sign stage.
Risk
REQUIRED: Check exactly one box.
Pipeline YAML only — no runtime code changes. The added step is read-only verification (codesign --verify) that fails fast rather than publishing a bad artifact. No customer-facing behavior is affected.
