In the latest version of macOS, turning on kernel extensions does not require turning off system integrity protection. System integrity protection is a security mechanism that prevents unauthorized programs or processes from modifying the core parts of the operating system, thereby protecting the stability and security of the system. In earlier versions, turning on kernel extensions required turning off system integrity protection. However, in macOS High Sierra and later versions, Apple provides developers with a new API that allows developers to turn off system integrity protection without turning off system integrity protection. Development and debugging of kernel extensions without protection. Therefore, in the latest macOS version, turning on kernel extensions does not require turning off system integrity protection, but you need to ensure that the kernel extensions used have valid signatures and authorizations.
