A copyeditor would no doubt have picked up the mistake, but Mac spared me that embarrassment.

校对编辑无疑会发现这样的错误，但麦克让我免于丢人现眼。

There'll be plenty; only God gets it right the first time and only a slob says, “Oh well, let it go, that's what copyeditors are for.”

肯定有不少这样的错儿，只有上帝才能在头一遍就写得完美无缺，也只有邋遢笨蛋才会说：“得了吧，由它去，编辑就是干这个的。”
