From the developer:
SafariBookmarkChecker is a tool to help you manage the bookmarks you have stored for years. It starts with reading the bookmarks from Safari (making a backup copy for safety), then let you do an extremely fast scan to detect bookmarks which have changed or are not available anymore. Its main feature is speed! It can check over 1000 bookmarks in less than 2 minutes, a performance similar programs don't even come close.
