mac os x server meaning in English

最强大安全的系统

Also , i should mention - but not overemphasize - the little matter of cost : an unlimited - client version of mac os x server will cost you us 1000 per machine , whereas linux is free of cost and even a support contract from a distribution vendor is much cheaper than this
而且，我要提及但不是强调有关费用的小问题：一个不限制客户端数目的mac os x服务器版本每台机器需要花费您1000美元，而linux是免费的（即使是发行商的支持合同，与此相比也便宜得多）。
