I need to inspect different act stacks. Thanks. P.S. I seem to remember this working under 10.3.x, but I could be wrong.

I'm investigating a kernel core and trying to use kgmacros' switchtoact. It keeps failing with a memory error though. So the macro is trying to change memory and failing to do so. A manual set gives the same error: This must be because the core is not real memory, but a read-only snapshot. This email sent to site_archiver@lists.apple.com
