Pull Request Overview
This PR backports test fixes for macOS 26 Tahoe to the release/8.0-staging branch. The changes address test failures that were occurring specifically on macOS 26 RC by updating platform detection logic and adjusting test expectations to accommodate behavioral changes in the newer macOS version.
Key changes:
- Adds detection for Apple platforms version 26 or later
- Updates X509 certificate chain test logic to handle macOS 26 behavior differences
- Adjusts test assertions for certificate chain validation on the new platform
