如何在macOS上使用GDB调试器？

我目前使用的是2012年年中运行macOS Mojave 10.14.5版的macbook Pro。我正在尝试使用GDB调试器调试C语言代码。我已经用自制软件在我的电脑上安装了gdb，但它似乎不起作用。以下是我在VSCode中从终端获得的输出：

我不确定我是否错过了一步，或者我是否应该做些什么来代替使用自制软件，但任何建议都是有帮助的

提示是这一行：请检查gdb是否进行了代码签名-请参阅taskgated8

由于苹果的安全特性之一，您需要对GDB进行代码设计。方法如下：

我尝试了链接中的内容，但不起作用。我仍然得到与上面终端相同的结果，我相信我可能已经得到了。我在这里遵循以下指示：
