I get some problems when I tried update macbrew.
After
sudo chown -R $(whoami) /usr/local
I didn't get problems.
√ /usr % echo $(whoami)
tortuesbranchees
Return the name of the owner of the current session.
cd /usr
ls -al
will return
drwxrwxr-x 18 tortuesbranchees admin 576 6 oct 08:03 local
The solution is probably not perfect because another user will not been able to update macbrew
