近日，苹果公司承认，其独立式桌面电脑Mac Pro的设计限制了该产品的更新换代。

　　The firm has announced a limited refresh of the machine, the first time it has upgraded its innards since 2013.

　　该公司于日前发布了该机型一次改动不大的更新，这是自2013年以来第一次升级内部结构。

　　But it said it would not be able to release a "new model" until an unspecified point after 2017. The tech firm had faced criticism that it was not addressing the needs of its professional users.

　　但苹果公司表示，他们不会在2017年的某一天发布新款Mac Pro。这家科技公司也因此受到了很多指责，因为现在的电脑版本并不能解决那些专业用户的需求。

　　苹果公司承认Mac Pro的设计是一场失败的赌博

　　It released a new line-up of MacBook-Pro-branded laptops in October, but was attacked for not including more powerful graphics cards in them and for removing several of the ports found in earlier models.

　　苹果公司在去年10月份的时候发布了一系列名为“MacBook-Pro”的笔记本电脑，但是因其没有更加先进的显卡，并且移去了一些原有接口，从而饱受人们的诟病。

　　I think it was simply untenable for Apple to continue to remain silent on the Mac Pro front, commented the tech blogger John Gruber.

　　科技博客作者约翰·格鲁伯评论称：“我认为苹果一味地在Mac Pro的阵线上无所作为，这是岌岌可危的。”
