Use of Breakout on macOS

Newer versions of macOS won’t allow binaries to execute if they are not from a “trusted developer”. This typically means, that the binary has to be signed. If the downloaded binary is started either by double-clicking in the Finder or via the CLI in a terminal, the following dialog can be seen:

The Breakout utility is not digitally signed (yet) and therefore, the following steps need to be followed to allow the execution of the Breakout utility on macOS:

The operating system “remembers” this override and from now on it’s possible to run the Breakout utility without going through additional security warnings / pop-ups.
