I uninstalled Homebrew, manually removed the /usr/local contents.
The following possible Homebrew files were not deleted: /usr/local/.DS_Store /usr/local/bin/ /usr/local/etc/ /usr/local/include/ /usr/local/lib/ /usr/local/libexec/ /usr/local/share/ /usr/local/texlive/ /usr/local/var/ You may consider to remove them by yourself. You may want to restore /usr/local's original permissions sudo chmod 0755 /usr/local sudo chgrp wheel /usr/local
I want to know what the suggested commands do.
/usr/local/texlive/is the result of installing TeX. If you still use this, you probably shouldn't delete the directory...
