Homebrew Tap for Valgrind macOS

First, tap this repository:

brew tap LouisBrunner/valgrind

Then, install valgrind:

brew install --HEAD LouisBrunner/valgrind/valgrind

You can now use valgrind as normal.

Any brew upgrade will now correctly rebuild the latest LouisBrunner/valgrind instead of the upstream one (which doesn't support latest macOS versions).

brew upgrade --fetch-HEAD LouisBrunner/valgrind/valgrind
