I've used TinkerTool to change all my system fonts to Helvetica Neue (Ultra Light) but I'm not completely satisfied, as Lucida Grande is still lingering around, most notably in the menubar, dock, Finder, login window, etc. As I don't use Lucida Grande for word processing, I'm thinking I might replace the actual file with Helvetica Neue, but using the Lucida Grande filename, so hopefully Mac OS will pick it up and use it. Can anybody confirm if this works and/or let me know if this is a good idea? I don't particularly want to break my system... I'm running Snow Leopard 10.6.5. Thanks, Tim.
