Hardware scope and limitations
This fork specifically targets FocalTech PS/2 trackpads. It is not intended to replace the normal upstream VoodooPS2 plugins for Synaptics, non-FocalTech ELAN/Elantech, ALPS, Sentelic or generic PS/2 mouse/trackpad hardware.
- FLT0101 — hardware validated; mux-safe i8042 path; do not use
foclegacy=1. - FLT0102 — hardware validated; simple AUX compatibility path; use
foclegacy=1. - FLT0103 — protocol support is experimental and not yet hardware-validated.
- Other/unknown FocalTech PS/2 devices may be tried, but are experimental until physically validated.
- Validated on macOS Sequoia and macOS Tahoe on tested FLT0101/FLT0102 hardware.
Confirmed functions
Cursor movement, native multitouch through VoodooInput, macOS gestures, left/right click, dragging, progressive Force Click / Look Up emulation, sleep/wake reinitialization, and mux-safe probing.
Important for OC Auxiliary Tools (OCAT) users
If OC Auxiliary Tools (OCAT) reports an update for VoodooPS2Controller.kext on a machine using this fork, do not let OCAT replace this fork's VoodooPS2 stack with the stock Acidanthera build unless you intentionally want to remove FocalTech support.
The patched controller can have a different file size and hash/MD5 from Acidanthera's stock binary even when the displayed version number is the same. OCAT may therefore show the stock package as an available update. That difference is expected and is not an error. Replacing this fork can remove the FocalTech compatibility path and stop the trackpad.
Update this FocalTech stack from this repository's Releases page.
Versioning note
The public release number follows Acidanthera's VoodooPS2 release line. This fork is not byte-for-byte identical to the upstream binary because it includes the FocalTech-specific controller and trackpad changes documented in this repository.
