我想在OS X El Capitan上向/ usr/bin移动一些东西.我使用以下命令禁用了rootless:sudo nvram boot-args="rootless=0"; sudo reboot但是我一直收到同样的错误:
MacBook-Air:~ Mark$ sudo cp class-dump /usr/bin
Password:
cp: /usr/bin/class-dump: Operation not permitted
MacBook-Air:~ Mark$ sudo mv class-dump /usr/bin
mv: rename class-dump to /usr/bin/class-dump: Operation not permitted
