Depending on the wallpaper I select in Mac OS X 10.6, the menu bar is semi-translucent. Ironically, on black backgrounds, this looks best, as it comes out a simple, flattish gray. On any background I select which has strong colors, however, it either becomes a distraction or (to me) makes the menu bar near-unintelligible.
The simple answer is to stick with less-bold backgrounds. But that really limits my selection, and I like to change things up every now and again.
Can the transparency be removed / toned down / adjusted in OS X 10.6?
