After these steps, you can see the new certificate under System keychains.

To give gdb those permissions, you need to generate a self-signed certificate.

For security reasons, this is the default behaviour. If you try debugging a file, you'll get an error since the Darwin kernel doesn't allow gdb to control another process without having special rights. Take note of the version: you'll need it later. To check out your gdb version, run: gdb -version In case you have already a newer version of gdb, you first need to unlink the other version before installing the old one. The pinning operation makes sure that brew doesn't upgrade gdb to newer versions. Should you decide to do so, you can install gdb version 8.0.1 in this way. Verify that the operation was successfull by running: gdb -version To install the latest version of gdb, run this command: brew install gdb In this tutorial, I'm going to use gdb 8.3. You can either use gdb 8.0.1 or one of the latest versions, starting from 8.3. If you're using High Sierra (macOS 10.13) or later, be aware that gdb 8.1 and 8.2 are not compatible.

Once you have Homebrew, you can install gdb. If you don't have it installed, open your Terminal prompt and write this command: /usr/bin/ruby -e '$(curl -fsSL )' The easiest way to install gdb is by using Homebrew: 'the missing package manager for macOS'.

Troubleshooting the Eclipse configuration.Troubleshooting the certificate generation.Starting from Mavericks (macOS 10.9), there are several steps to follow to make it work. Using gdb debugger on macOS is no longer straightforward since Xcode stopped using it and replaced it with lldb.
