Not Your Mac, Anymore
I can’t attach to TextEdit because of system integrity protection?
the point of the thing is to prevent software to do damage to the system where a user gave their admin password.
How does preventing debuggers attaching to unimportant processes match that intent?
you may be able to copy TextEdit to your Desktop and attach to a running instance of it, if SIP is still broken in this way
the ominous wording when you disable SIP seems quite worrying: “… is an unsupported configuration, likely to break in the future…”.
TIL rootless has the ability to disable protections for one specific class if you only need to change one thing!
Update (2015-12-10): Paul Kim:
I can’t attach to SysPrefs with SIP. We’re not talking about hacking things here. SysPrefs has a officially sanctioned plugin API.
