因为黑苹果无线网卡无法驱动导致不能上网，所以我选择用HoRNDIS驱动，来使我的黑苹果能够通过安卓手机的USB网络共享功能来上网。
下载HoRNDIS驱动网址：https://joshuawise.com/horndis
由于我的黑苹果系统为BigSur，所以我选择下载了 HoRNDIS-9.2.pkg 。
下载完成后，双击安装，会发现安装失败，按以下步骤解决：
I come back with good news: I finally made it work ! Thank a lot to Prophetia086 and to others tips I collected here, here and there to make it work. Here is my path :
First, we need to get the developer ID and check whether that extension has been notarized. One easy way to do this is to type most of the command
• spctl -a -vv -t install
then drag and drop the extension from your Downloads folder to the end of that line, where its path and name should appear, e.g. /Users/Downloads/Horndis.kext
Then press Return, and you should see three lines of response:
• mykext.kext: accepted
• source=Developer ID
• origin=Developer ID Application: DeveloperName (54GTJ2AU36)
If the extension is notarized already, they will instead look like
• mykext.kext: accepted
• source=Notarized Developer ID
• origin=Developer ID Application: DeveloperName (54GTJ2AU36)
Make a note on paper or your iOS device of the developer ID provided in parentheses, as you’ll need those in a few moments.Close your apps down and restart your Mac in Recovery mode. There, open Terminal and type in the command
• csrutil disable
• /usr/sbin/spctl kext-consent list
If 54GTJ2AU36 is not in the list, enter
• /usr/sbin/spctl kext-consent add 54GTJ2AU36.
Press Return, wait for the command prompt to appear again, then quit Terminal and restart in normal mode.Remove Allow permission you provided earlier to Horndis (54GTJ2AU36). This is important to let your OS accept the device again. Follow these steps carefully:
• sudo su
(enter your password if prompted), then enter these four lines by sequence:
• sqlite3 /var/db/SystemPolicyConfiguration/KextPolicy
• delete from kext_load_history_v3 where team_id='54GTJ2AU36';
• delete from kext_policy where team_id='54GTJ2AU36';
• .quitManually erase any previous horndis.kext remained in library/extensions (just to be sure). Install Horndis 9.2 Catalina Install pkg). Now you will be prompt to Allow this driver in System Preferences -> Security & Privacy.
Restart in recovery mode to enable csrutil
• csrutil enableRestart in normal mode and enjoy it working (at least, for me it did work)
I am so happy I hope this walkthrough will help others people with the same issue on Big Sur. Yes, I almost forgot : I upgraded to Big Sur 11.1 before doing this whole process. It may have be helping.
重新安装HoRNDIS驱动。
最后，用USB线连接上安卓手机与MAC后，打开安卓手机上的USB网络共享，然后在MAC的网络设置中发现USB网络共享实现成功！
