I have just installed the latest Xcode (13.3.1) and am finding that when I attempt to build a kernel extension (which was compiling fine in 13.2.1) I encounter the following error:  error: use of undeclared identifier '__APPLE_CC__' This appears to be inside an auto-generated file named <TargetName>_info.c, located in ../Intermediates.noindex/<ProjectName>.build/Debug/<TargetName>.build/DerivedSources/ I couldn't see any reference to this change in the release notes for Xcode 13.3 or 13.3.1. From some reading it appears that __APPLE_CC__ is related to a C compiler version. Has anyone else encountered this or know whether this is a bug, or part of the deprecation of kernel extensions? Many thanks

I have been in the process of porting a helper tool from communicating with a Kext for kauth to using EndpointSecurity directly. All was going well until I re-enabled SIP at which point I discovered a provisioning profile would be required. As the helper tool is a plain executable this isn't possible but having read some forum posts regarding launchd daemons &amp; Endpoint security I attempted to package the helper tool as an .app wrapper. This isn't working so far (SMJobBless fails), so I'm beginning to think this isn't going to work... Any idea if this is achievable? Or am I going to have to re-work the ES logic in to a separate System Extension? Thanks, Adam
