MAC OSX El Capitan: Airport Sym link not permitted

问题:

I tried making a symbolic link to the airport command in MAC OS X El Capitan, using the command:

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport

It returned the following error:

ln: /usr/sbin/airport: Operation not permitted

Is this due to the El Capitan's "rootless" feature? The sym link worked fine in MAC OS X Yosemite.

回答1:

The target directory should be /usr/local/bin/airport

See the article on System Integrity Protection for more information as to why the directories have changed.

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/local/bin/airport
