Hi Oleg,

Is there a particular reason you're installing Octave into /usr instead 
of Homebrew's default location of /usr/local? /usr/bin is a 
system-controlled directory and is going to be protected using macOS's 
special access controls. You should not install anything there. Using 
Homebrew to install to /usr instead of /usr/local is not recommended or 
supported.

have to have Octave in its default directory to be installed on the system.

There is no single default directory for Octave: if you build from 
source it goes into /usr/local or wherever you point it; Homebrew puts 
it in /usr/local or whatever your $PREFIX is; MacPorts puts it in /opt 
or something like that; Snap and Flatpak put it wherever they put it; 
and Linux distributions put it in /usr. If your project requires the 
`octave` command, it should either use $PATH to locate it, or search in 
several locations for it. I'd suggest adding a specific 
$MYAPP_OCTAVE_HOME environment variable to your project so users can 
point it to wherever they have Octave installed. 'Tis the nature of Unix.

You can also install the Octave 6 release candidate with:

$ brew install octave-app/octave-app/[email protected]
