Please add a code to support MacOSX, it's easy: you just add custom scrollbars as it's done in iPox, Whitehart, Silvermel, Stratini, Rein, or in Smoke or FennecFox (not from default theme).

MacOSX (and Linux) support

Thanks for the tip. I was already looking into fixing this issue. It is just that I have no way to test any changes to see if they work properly. Have a look at my web page to see a transcript of what happened when I tried to get help with this the first time:
I may have found someone who can help with testing on Mac OSX and Linux.
I was recently looking at a theme not mentioned in your list that seems to have a simple solution. I will have a look at the ones you mentioned if I have difficulty with the present one.
