Hi, Type "import cairo" at your Python prompt. If it doesn't work, it means that Cairo was not installed properly (and this is what causes igraph to print "plotting not available"). It might be the case that you have multiple Python installations on your machine (e.g., the system Python and another one from Homebrew), and igraph was installed for one of them and Cairo for the other one.
