For enabling Universal Control on older Macs, there are three ways.

(All of these requires you to enable the feature flag and disable SIP)

• Use khronokernel's kext: https://twitter.com/khronokernel/status/1428407216931999749

(I haven't tried this but it looks like it'd work)

• use DYLD_INSERT_LIBRARIES:
