$ brew caveats osxfuse anaconda
==> osxfuse: Caveats
To install and/or use osxfuse you may need to enable their kernel extension in
    System Preferences → Security & Privacy → General
For more information refer to vendor documentation or the Apple Technical Note:
    https://developer.apple.com/library/content/technotes/tn2459/_index.html
You must reboot for the installation of osxfuse to take effect.

==> anaconda: Caveats
To use anaconda, you may need to add the /usr/local/anaconda3/bin directory to your PATH environment variable, eg (for bash shell):
    export PATH=/usr/local/anaconda3/bin:"$PATH"
Cask anaconda installs files under /usr/local. The presence of such files can cause warnings when running "brew doctor", which is considered to be a bug in Homebrew Cask.
