This bug (Apple's bug) still exists in macOS 13.0 Beta 2 (build 22A5286j).

Apple's bug still exists in macOS 13.0 beta 3 (build 22A5295h).

That's possible. But it may also just be an oversight -- Apple still supports them in macOS 13 "on bare metal". Only time will tell. I'll keep testing new Ventura...

Note that using Apple Virtualization works fine when installing Linux from an ISO, but only on macOS 13 (and up, presumably). I tried this on Intel hardware, but it should...

@dariaphoebe, I'm thinking of trying to debug this on an Intel Mac, since I can use [HookCase](https://github.com/steven-michaud/HookCase) there. Any suggestions how I might go about it, or is it a...

I've made some progress debugging this problem. But I haven't, unfortunately, found a workaround. And what I *have* found indicates it happens at a very low level, and is almost...

I've learned that "SEP" means "Secure Enclave Processor" ... probably. And "ACM" might mean "Authenticated Code Module".

After more digging around, I discovered there are three kernel extensions that can receive "SEP commands". (These are the only three kexts that have `readFromSEPBuffer()` commands.) ``` BootPolicy.kext AppleCredentialManager.kext AppleSSE.kext...

I've found out what "SEP command 33" is -- `_command_create_linked_manifest()` in `AppleVPBootPolicy.kext`. There's an array named `_command_functions[]`, and a pointer to `_command_create_linked_manifest()` exists in it at offset 33 X 8....

I've discovered some information about why `_validate_acm_context()` fails. But it's very cryptic, and I can't really interpret it: ``` kcgend: (libbootpolicy.dylib) [com.apple.BootPolicy:Library] BootPolicy: bootpolicy_create_linked_manifest: entry kernel: (AppleVPBootPolicy) BootPolicy: creating linked...
