Big Sur 11.2.2: Operation not permitted although Iterm and Terminal have Full disk access On Big Sur 11.2.2, Iterm and terminal are both granted &quot;Full disk access&quot; in system preferences &gt; security &amp; privacy &gt; privacy
I tried to install a third party app using
sudo wget https://github.com/Battleman/zoomdl/releases/latest/download/zoomdl -O /usr/bin/zoomdl

But I got the error
/usr/bin/zoomdl: Operation not permitted

I also downloaded the repo locally and granted full disk access to the zoomdl executable but got same error
What should I do?
You are supposed to install third party software to /usr/local/bin. This is the default used by most Unix installers and build systems.
(Alternative directories in the root for example under /opt can be used if you have fu;ll control of how the software is built)
The folder /usr/bin is protected by SIP as it contains software supplied by Apple as part of macOS (In Big Sur this is even more difficult if at all possible to alter)
