Set a watchpoint on a variable when it is written to.
(lldb) watchpoint set variable -w write global_var
(lldb) watch set var -w write global_var
(gdb) watch global_var
Set a watchpoint on a memory location when it is written into. The size of the region to watch for defaults to the pointer size if no '-x byte_size' is specified. This command takes raw input, evaluated as an expression returning an unsigned integer pointing to the start of the region, after the '--' option terminator.
(lldb) watchpoint set expression -w write -- my_ptr
(lldb) watch set exp -w write -- my_ptr
(gdb) watch -location g_char_ptr
Set a condition on a watchpoint.

  • Download OS X Mavericks from the Mac App Store, if you haven't already. If it tries to start the installation, just close it.
  • Insert your USB drive (you'll need one that's 8GB or larger) and open Disk Utility.
  • Select your drive in the sidebar and go to the Erase tab. Format the drive as "Mac OS Extended (Journaled)" and name the drive "Untitled." (Note: if you already have a drive or partition named "Untitled" connected to your computer, name it something else and change the corresponding variable in step 5's terminal command, or you might experience data loss!).
  • Click the Erase button and wait for Disk Utility to finish.
  • Close Disk Utility and open up a Terminal window. Copy and paste the command into the Terminal.
sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointe
