The Borkware NSLog replacement seems like a rather a large amount of overkill and unnecessary clutter. __FILE__ and __LINE__ should always be implicit parameters instead of having to be passed into a method, every time. Not a MLog() wrapper that calls a singleton to make them implicit.

I personally like to define a Log() as:

  #ifdef DEBUG
	#define MYLog(fmt, ...) NSLog(@"%s: " fmt, __PRETTY_FUNCTION__, ##__VA_ARGS__)
  #else
  	#define MYLog(...)
  #endif

This way, I can log on debug builds only (add -DDEBUG as an "Other C Flag" to Xcode), and it gives me the method name that it was called on. Just enough context to be useful to track something down, not enough to cause a sea of output noise.

You can use any of the C preprocessor macro's[1] this way.
