U need to find the config.plist and kexts for the exact Thinkpad model.

people who are making hackintosh will buy a real eventually. The M1 chip still in its infancy, though it performs way better than the intel counterpart. many mac user will loose windows capability in bootcamp if they jump into M1 bandwagon now. So hackintosh is way to go before Arm Based Windows, AAA games, APPs. GPU drivers, Mining taking advantage of ARM which very far in the future. IMO
