I think you want condition-case.
The following command executes the current macro as many time as possible,
but goes to the end of buffer instead of beeping and aborting on the final 
error. Replace end-of-buffer by save-buffers-kill-emacs if you want to quit 
emacs instead of going to the end of the buffer.

(defun exec-macro-without-error ()
"exec current macro repeatedly until an error is encountered,
 but don't beep and report error. Instead go to the end of buffer."
 (interactive)
 (condition-case nil
    (kmacro-end-or-call-macro 0)
   (error (end-of-buffer))))

See  Handling Errors  in the elisp manual for details.
