macOS 15 Wireless Sidecar Black Screen Issue — Possibly Caused by Video Stream API Changes, Can OCLP Patch This?

Body:

Hello developers,

After upgrading to macOS 15, I encountered an issue where wireless Sidecar no longer works properly:

  • Device: Laptop, Intel Core i7‑9750H
  • GPU: Intel UHD Graphics 630 (hardware acceleration enabled via OCLP Root Patch)
  • iPad: iPad mini
  • OCLP Version: Latest Nightly build

Issue:

  • Wired Sidecar works normally
  • Wireless Sidecar connects successfully, but the iPad screen immediately goes black

Possible Cause (based on the symptoms and known technical background):

  • macOS 15 may have made low‑level changes to Sidecar’s video stream handling
  • Some calls may have been migrated from the legacy AppleGVA / VDADecoder interfaces to new APIs
  • OCLP’s current patches still rely on the old interfaces, causing the wireless mode to fail to establish the video stream and resulting in a black screen

Request:

  • Is there any plan for OCLP to implement a compatibility patch for macOS 15’s new video stream APIs?

Thank you for your hard work and support!
