There are a number of Mac-ish backgrounds in the wallpaper library here. Just search the library for words like Mac, Apple, Aqua, OSX. You won't find any actual Mac wallpapers here though. They are copyrighted property of Apple.

Do you want background to put on a Mac, or do you want Mac-loking background to use on a PC?

you can use any of the wallpapers posted here as desktop pics for your mac. when you download them, they will appear on your machine as something like 'wincustomize.asp1' etc., etc. drag these files onto your copy of stuffit expander [double clicking won't work in this case, since it won't recognize the filetype by default.] after you drop it on stuffit, they will expand into the image file, or in some cases a folder with several images within. you can apply these images in the usual manner

listen to migellito

After you have done what migellito said, if the wallpaper is in .bmp format, you have to convert them first, (with GraphicConverter, Photoshop etc), in .jpg or .pict format.
