I send yesterday on Aminet my pic/wb of use VisualPrefs Aqua MacOS X like.
Here is preference for use with VisualPrefs 1.5 and more.
Installation: just unpack and copy all in SYS:prefs/presets/
Usage: start GUI of VisualPrefs and OPEN my prefs in
       SYS:prefs/presets/VisualPreAQUA2.pre. Turn gadget on System,
       open Bitmaps and choose AQUA. Now You can see in prefs,
       how it looks. Now just save it.

It's my first AQUA-like WB. Work isn't finish, I will be update it.
Stay tuned.

Sorry for my bad english.
