Still broken in 14.4.1. Quality software by Apple. Top notch.

The solution is very simple: stop using SwiftUI, which is a broken mess, and instead use UIKit, where all this Just Works®.

Now broken in macOS 14.3 beta 1.

Hello @eskimo, When using the amfi_get_out_of_my_way bootarg to enable an Endpoint Security system extension loading, on macOS Sonoma 14.2 (all betas so far), there seems to be a bug introduced where task_set_exception_ports and related APIs fail with GUARD_TYPE_MACH_PORT: Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_GUARD (SIGKILL) Exception Codes: GUARD_TYPE_MACH_PORT Exception Codes: 0x00000000000048e0, 0x0000000000000000 Termination Reason: Namespace GUARD, Code 2305843035510950112 Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x18c8e0854 mach_msg2_trap + 8 1 libsystem_kernel.dylib 0x18c8f2cd0 mach_msg2_internal + 80 2 libsystem_kernel.dylib 0x18c90ac78 task_swap_exception_ports + 368 This affects a lot of third-party software, such as 1Password, Firefox, Tower, etc. In the past, another boot arg was needed to prevent crashes: ipc_control_port_options. Is there anything new introduced in Sonoma 14.2 in this regard? Thank you in advance
