Under the Apple system, the driver must be signed before it can be loaded normally, and the ordinary developer certificate is invalid for the driver, so you need to apply to Apple for driver signing permission separately. By default, both individual developers and company developers have only ordinary program signature rights, and no driver signature is restricted. A simple way to judge is to look at the extension of your signature certificate. If it contains (1.2.840.113635.100.6.1.18), it can be signed, otherwise it is invalid. The default signing certificate extension is (1.2.840.113635.100.6.1.13).

Now Apple's signature review of the driver is very strict, and it is difficult to apply successfully. If you have this demand and your procedures are legal, you can cooperate with them.
