I'd like to use homebrew to install encfs on macOS. Ideally, this would look like:
brew install macfuse
brew install encfs
As of macOS 12/Monterey, the first command works, but the second one does not, yielding†:
$ brew install encfs
Error: encfs has been disabled because it requires closed-source macFUSE!
How can I install encfs using homebrew?
† There is an inherent irony here in that we can directly install macfuse, but can't directly install another library dependent on (closed-source) macfuse. If I understand correctly, this happens because macfuse is distributed as a binary, and therefore it's formula is allowed in the official homebrew-cask. encfs is not distributed as a binary, and therefore is not allowed in homebrew-cask, and must remain in the more stringently-ruled homebrew-core; thus the error message. Whew!
