I see a black vertical line even with isOpaque is NO.
Is a way to draw it as transparent?

- (void)drawDividerInRect:(NSRect)aRect
{
   [[NSColor clearColor] set];
   NSRectFill(lineRect);
}

NSRectFill(x) is the same as NSRectFillUsingOperation(x, NSCompositeCopy), which won’t use the alpha data. You should be using the NSCompositeSourceOver compositing operation instead.
