Enable multiple users to install software using homebrew

set umaskfor each user first. (.basrc or .profile or .bash_profile)

umask 0002 # group write permission

then give write permission for groups via /usr/local recursively:

sudo chmod -R g+w /usr/local/

then change the owner to staff

sudo chgrp -R staff /usr/local

now, each user, who is in staff group can use brew install and other brew related operations... Mostly every user is in that group.

In case your account has root / su / sudo access, you can try the following workaround:

su - myother_user_account -c "brew install ..."

sudo alternative:

sudo -u myother_user_account brew install ...

A handy shell alias (for .bashrc/.zshrc/...):

alias brew="sudo -u myother_user_account brew"
