additional unspecified bug fixes

Key Fixes in macOS Tahoe 26.4.1

• Wi-Fi connectivity fix (enterprise/networking): Resolves an issue where M5 MacBook Air and M5 Pro/Max MacBook Pro models failed to join 802.1X Wi-Fi networks when using content filter extensions. This was the main documented fix.
• Folder icons on Intel Macs: User reports and reader feedback indicate it restores broken or missing custom folder icons (which appeared as generic blue folders after the 26.4 update on some Intel-based systems).
• Possible additional unspecified bug fixes (e.g., related to general stability or iCloud syncing issues seen in companion iOS/iPadOS 26.4.1 updates).
• No developer-specific new APIs or features were added in the 26.4.1 point release (those were in the prior 26.4 update).
