How to install Valgrind on macOS Catalina (10.15) with Homebrew?
I tried to install Valgrind with command brew install Valgrind and I get a message says:
"valgrind: This formula either does not compile or function as expected on macOS versions newer than Sierra due to an upstream incompatibility. Error: An unsatisfied requirement failed this build."
I also tried to "brew edit valgrind" and replace "sourceware.org/git/valgrind.git" with "git://sourceware.org/git/valgrind.git" in head section of the code, then wrote on Iterm "brew install --HEAD valgrind" but it gives me:

Answer
See https://github.com/LouisBrunner/valgrind-macos/.
Either try
brew tap LouisBrunner/valgrind
brew install --HEAD LouisBrunner/valgrind/valgrind
Or compile it from the source, if the above method doesn't work. (But they should have fixed the above method just recently.)
git clone https://github.com/LouisBrunner/valgrind-macos.git
cd valgrind-macos
./autogen.sh
./configure --prefix=/where/you/want/it/installed --enable-only64bit
make
sudo make install
Enjoy!
