Homebrew refuses installation of formula which requires macFUSE after April 8, 2021. It is done by checking if the following lines are written in the formula:
on_macos do
disable! date: "2021-04-08", because: "requires closed-source macFUSE"
end
This repository stores such formula but the above lines are removed (or, change the date to 3021-04-08 if on_macos contains more than one line).
Typically this repository is updated automatically every midnight JST.
