| ; WARNING: The sandbox rule capabilities and syntax used in this file are currently an |
| ; Apple SPI (System Private Interface) and are subject to change at any time without notice. |
| ; Apple may in future announce an official public supported sandbox API, but until then Developers |
| ; are cautioned not to build products that use or depend on the sandbox facilities illustrated here. |
| |
| ; Use "debug all" to log all operations examined by seatbelt, whether allowed or not. |
| ; Use "debug deny" to log only operations that are denied by seatbelt |
| ; to discover what specific attempted operation is causing an exception. |
| |
| ;(debug all) |
| (debug deny) |
| |
| ; To help debugging, "with send-signal SIGFPE" will trigger a fake floating-point exception, |
| ; which will crash the process and show the call stack leading to the offending operation. |
| ; For the shipping version "deny" is probably better because it vetoes the operation |
| ; without killing the process. |
