Note: LLDB Debug OS X Application

The LLDB Debugger, as it’s said on http://lldb.llvm.org/:

LLDB is a next generation, high-performance debugger. It is built as a set of reusable components which highly leverage existing libraries in the larger LLVM Project, such as the Clang expression parser and LLVM disassembler.

I was trying to find an OllyDBG-like debugger on OS X, gdb & lldb are the two choices.
Affinic.com has GUI for these two debuggers, not so good.
Hopper Disassembler provides it’s own GDB Server app, still bad.

Only commands here:
