[Mac OS X] 如何解决 “dtrace cannot control executables signed with restricted entitlements”?

​本文转载并参考至：http://stackoverflow.com/questions/33476432/is-there-a-workaround-for-dtrace-cannot-control-executables-signed-with-restri

在 OS X 10.11 El Capitan环境下，执行如下命令时会报错：

sudo dtruss /bin/ls

dtrace: failed to execute /bin/ls: dtrace cannot control executables signed with restricted entitlements

一个workaround就是把对应的binary拷贝到那些非“restricted"的位置，如/tmp

如下：

sudo dtruss /tmp/ls

试了一下，可以正常动作。
