How to use Homebrew on a Multi-user MacOS Sierra Setup (4)
Hombrew installs packages in
/usr/local, there is nothing you can do about that without breaking many of the packages it installs. Add read and write permissions for all users like this:
sudo chmod -R +rw /usr/local
Be aware the since this is a system folder, all users will share the same brew installation. One user can remove packages that others have installed, and so on. So make sure to coordinate to avoid problems.
I have a Mac that is shared between two engineers. Both have separate user accounts. Both need to run
brew update and
brew install... occasionally.
How do I set this up without getting errors like:
/usr/local must be writable!?
Yeah, I could have
UserA take over the permissions of
/usr/local every time he wants to use brew (and same with
UserB), but that seems like a lot of unnecessary trouble.
The above solutions didn't work for me. But running the command below worked for me.
sudo chown -R $(whoami) $(brew --prefix)/*
The best solution is to add a sudoers record to allow unprivileged user 'joe' to execute any 'brew' related command as the administrative user.
Create a file at /etc/sudoers.d/joe with following content:
joe ALL=(administrator) NOPASSWD: /usr/local/bin/brew
Then you can run brew like this:
sudo -Hu administrator brew install <smth>
You can also change the group permissions to admin or another group that both of your users are in:
chgrp -R admin /usr/local chmod -R g+w /usr/local

In macOS High Sierra you can't change the owner, group or permissions of
/usr/local. So you have to change the group and permissions of the subfolders:
chgrp -R admin /usr/local/* chmod -R g+w /usr/local/*
UPDATE September 2018, High Sierra 10.13.6
- Determine the path of the brew prefix, ie. the path that will be used to store files related to working with homebrew
- Check that all users on the system who need access to
breware in the admin group
- Optional Add a user to the admin group if a user needs access to brew
Will require access / privileges to use the sudo command
- Set the brew prefix path to be recursively owned by the admin group
- Set the brew prefix path to be recursively writable by all users who are in the admin group
- Verify the permissions of the brew prefix
- brew 🍻
echo $(brew --prefix) echo $(groups $(whoami)) sudo dseditgroup -o edit -a $(whoami) -t user admin sudo chgrp -R admin $(brew --prefix) sudo chmod -R g+rwX $(brew --prefix) ls -lah $(brew --prefix)
