wireguard tools cannot be installed on macos

My mac os version is Sonoma 14.4

I am installing wireguard tools from:

https://git.zx2c4.com/wireguard-tools/about/

Here are the steps I followed:

1) git clone <url above>

2) cd src; make

3) make install

At step 3 I get this error:

install: chmod 755 /usr/bin: Operation not permitted

install: /usr/bin/wg: Operation not permitted

make: *** [install] Error 71

I tried:

1) sudo make install

sudo does not accept my password

2) sudo -s

Again I got the error messages above even though I was root.

bash-3.2# whoami

root

The /etc/sudoers file does contain 'admin'.

# root and users in group wheel can run anything on any machine as any user

root      ALL = (ALL) ALL

%admin     ALL = (ALL) ALL

How should I proceed ?

Many thanks.
