我正在尝试移动一些东西到OS X El Capitan上的/usr/bin。我使用以下命令禁用了root - less: sudo nvram boot-args="root - less=0";sudo重启,但我一直得到相同的错误:
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
