after several days of tossing and turning, I finally toss about the Hackintosh (Black Apple) of my desktop at home. It's no big problem to use it as a productivity tool on a daily basis. Now I'm waiting for the drive-free BCM94360CD network card to arrive, and then I can use the two functions of Airdrop Handoff with pleasure.

the reason for choosing this version is that the highest Hackintosh driver of the N card is supported to this version, and the later version N card is equivalent to being obsolete. Wait for the opportunity later or on the A card, you can support to the latest macOS Big Sur.

when messing with the old version of the system, it is important to note that during installation, change the installation time to the release time of the version of your installation system, so as not to prompt the error of out-of-date resources.
