Additional Notes

• NightShift (macOS 10.12.4+)

• AirPlay to Mac (macOS 12.0+)

• Universal Control (macOS 12.3+)

  • Requires minimum of Wifi N and Bluetooth 4.0 for wireless, wired is supported between iPad and Mac as an alternative
  • Note all parties check each other for compatibility, thus requiring FeatureUnlock on all models in the chain
    • Seen as Ineligible Device Found Md MacBookPro11,4, SV 340.17.2 in Console under UniversalControl: com.apple.universalcontrol
    • Recommend using a different SMBIOS if possible, otherwise use -force_uc_unlock for machines that are not blacklisted but are connecting with a blacklisted model.
    • Due to the nature of requiring FeatureUnlock for both models, Apple Silicon and iPads will not work

• Sidecar (macOS 10.15.0+)

  • Requires minimum of Wifi N and Bluetooth 4.0 for wireless, wired is supported between iPad and Mac as an alternative
  • Requires a machine with an Intel iGPU active for reliable usage, most dGPU-only machines will experience difficulties. An H.265 capable iGPU is recommended for best streaming quality.
  • AMD dGPU-only machines may work if using an iMac19,x or iMac20,x SMBIOS with gvaForceAMDKE setting applied:

defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes

Boot arguments

• -caroff (or -liluoff) to disable
• -cardbg (or -liludbgall) to enable verbose logging (in DEBUG builds)
• -carbeta (or -lilubetaall) to enable on macOS newer than 13
• -allow_sidecar_ipad enables Sidecar support for unsupported iPads (only functional with iOS 13, iOS 14+ implements an iOS-side check)
• -disable_sidecar_mac disables Sidecar/AirPlay patches
• -disable_nightshift disables NightShift patches
• -disable_uni_control disables Universal Control patches
• -force_uni_control forces Universal Control patching even when model doesn't require
