解决了!

NSAttributedString 文档说 NShadowAttributeName 的默认值为 nil，但在这种情况下，按钮标题是用白色阴影绘制的。透明阴影解决的问题:

NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowColor:[NSColor colorWithDeviceWhite:1.0 alpha:0.0]];

NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                 shadow, NSShadowAttributeName, nil];

NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:_customTitle attributes:attrsDictionary];

[mybutton setAttributedTitle:attrString];
