Apple - Is anyone else having problems with using htop on High Sierra?

I the meantime lots of people have reported the same behavior on GitHub.

Also, I'm 96.73% sure that htop does not crash when started with sudo. I guess that's the best workaround until someone gets around to fix the root cause.

I found another (safer than sudo) workaround: launching it with valgrind does the trick for me:

valgrind htop

you can install using Homebrew by running:

brew install valgrind
