An open source kernel extension bringing a platform for arbitrary kext, library, and program patching throughout the system for macOS.
- Generic kext patcher
- Generic process patcher (64-bit with basic 32-bit functionality)
- Generic framework/library patcher (64-bit with basic 32-bit functionality)
- Provides a unified plugin API
You should install this kext along with the plugin kexts depending on it.
The prebuilt binaries are available on releases page.
Several existing plugins possibly with code samples are available on known plugins page.
To compile a plugin copy the debug version of Lilu.kext into its directory.
Add -liludbg to enable debug printing (available in DEBUG binaries).
Add -liludbgall to enable debug printing in Lilu and all loaded plugins (available in DEBUG binaries).
Add -liluoff to disable Lilu.
Add -liluslow to enable legacy user patcher.
Add -lilulowmem to disable kernel unpack (disables Lilu in recovery mode).
Add -lilubeta to enable Lilu on unsupported os versions (10.13 and below are enabled by default).
Add -lilubetaall to enable Lilu and all loaded plugins on unsupported os versions (use very carefully)
Add -liluforce to enable Lilu regardless of the mode, OS, installer, or recovery.
Most of the plugins cease to function in safe (-x) mode.
By default Lilu itself does not function in single-user (-s) mode, unless -liluforce is present.
