Description
https://docs.libretro.com/guides/input-controller-drivers/
shows multi-mouse support for Linux udev and Windows raw... but nothing for macOS.
RetroArch is currently using Cocoa API and HID Manager.
For comparison, https://github.com/icculus/manymouse supports multi-mouse on Macs using the older Carbon API and HID Manager. (A quick test indicates that works in Cocoa as well.)
(I've been able to use manymouse in libretro-dice to get basic functionality, but have too many multi-thread double-free and crash-on-exit issues to make that production code --- so integrating multi-mouse into the RetroArch input driver might scale better.)

Research direction
Start with the input controller driver guidance at docs.libretro.com and compare the macOS Cocoa/HID Manager path with the manymouse implementation linked in the issue. Determine how multi-mouse support should fit into RetroArch's macOS input driver and verify that the result avoids the reported multi-threaded double-free and crash-on-exit problems.
