Note: Sidecar 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 the following applied:

defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes

AirPlay to Mac does not have such limitation and can work on H.264 dGPUs. However requires macOS 12, Monterey or newer to use

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 12
• -allow_assetcache enables Content Cache support for systems exposing kern.hv_vmm_supported
• -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/Universal Control patches
• -disable_nightshift disables NightShift patches
