来源：环球网 【环球网科技综合报道】12月17日消息，据知名科技媒体MacRumors报道，苹果公司正在秘密研发一款 搭载M5 Max芯片的高端iMac。 此次发现源于苹果工程师所使用的Kernel Debug Kit（内核调试工具包）文件。这类文件堪称苹果硬件 的"秘密档案"，通常会通过内部识别码、平台名称和代号，详细列出尚未发布的苹果硬件信息，同时还 可能包含平台标识与芯片代号及市场命名之间的对应关系，为外界窥探苹果新品提供了重要线索。 不过，MacRumors也谨慎地指出，这些内核调试文件中包含了不少明显仅用于内部测试的设备。例如， 运行tvOS的iPad mini以及搭载A15芯片的MacBook，这些设备大概率不会面向市场推出，仅作为苹果内 部工程验证的工具。所以，这款搭载M5 Max芯片的iMac机型，同样存在仅用于工程验证的可能性。 但从另一个角度看，M5 Max芯片预计将在明年正式推出，而且多年来外界一直有传闻称苹果将重新推 出高端"Pro"级iMac。 除了这款神秘的高端iMac，泄露信息还显示，苹果正在测试一款搭载A18 Pro芯片的MacBook。鉴于A 系列芯片通常应用于苹果的移动设备 ...
