重装系统机器码会不会变
作者：我是四海飘零
前言
在烟草公司工作的朋友，也就是我一个关系很铁的哥们在今年这个月（2023年2月10号）帮他女朋友捡漏到了一台集团公司领导退库的MacBook Air 2018款苹果笔记本电脑。
这是一台MacBook Air 2018款，Retina高清屏，Intel Core i5双核处理器+8GB内存+128GB SSD的版本，公司购于2019年4月份采购。按照当初7800元的采购价，套用集团退库设备的折旧费计算公式：采购原价格*（1-5%）/折旧年限（n）/使用月份（12）*入职年限（x）。
折旧费：7800(1-5%)4125771.875，实际安装四舍五入是772元拿下这台MacBook Air 2018款的苹果电脑，你说香不香。
macOS Mojave
我哥们当时去退库的设备间里看到这台MacBook Air 2018还是比较脏的，电脑的机身上表面全是灰尘。正好这台也在退库的清单上，可以企业员工内购，所以就开机看看能不能正常运行。
不得不说这台MacBook Air 2018款开机实在是太慢了，完全不像是有固态盘的样子。进系统里查看才知道，原来系统还是macOS Mojave（10.14.4）版本，这都多久之前的系统了。好在屏幕的确是Retina高清屏，分辨率：25601600。的确是128GB的固态盘，就是固态盘的可用空间只有56.34GB。我估计就是因为开机反应慢+固态盘容量小才会被哥们集团公司领导弃用了，不然不会在退库设备间里堆放到布满灰尘。
MacBook Air 2018的电源线和充电头
我哥们决定赌一把看看，如果按照集团公司折旧费计算大概就是不到800元，但是一旦从公司退库设备间买走了，后面是好是坏则全由自己承担。好在哥们有仔细检查MacBook Air 2018的电源线和充电头，发现也就是线材的外表显得脏了些，并没有出现线材断头的情况。
这个是买回来后重新做了消毒和清洁，肉眼可见的会有划痕和一些脏的物质，这个是擦拭了好几遍最后的样子，算是比较干净了。
30W USB-C苹果原装充电器，输出：20V-1.5A（30W）、15V-2A（30W）、9V-3A（27W）、5V-3A（15W）。
从这个角度看已经是花了不少心思做清理的，但是线材上的污渍的确是不太好清理，但是胜在是原装线脏点又不是不能用？
看到这里我才明白原来这台MacBook Air 2018是港版的机器，难怪之前在退库设备间里一直放着吃灰。后面是我帮哥们找到一个英标（港版）插头转国标插头的转换插座。
MacBook Air 2018 Retina
MacBook Air 2018款都是重新擦拭干净后才摆拍的，拍摄的环境远比之前仍在退库设备间里杂乱环境强很多。当然机身上肯定会有一些轻微的划痕和轻微磕碰的印记，但并不是很明显。
我哥们说如果是金色款的MacBook Air就更好了，但是800元不到能收到一台成色很不错的MacBook Air 2018款已经算是超级捡漏王了好嘛！做人要知足常乐。
MacBook Air 2018款的四个脚垫也有明显的使用后的痕迹，不过也已经很用心的擦拭干净了。
这台MacBook Air 2018款在机身I/O接口方面只有两个雷电3的USB-C接口和一个3.5mm音频接口。我查询过苹果官网说MacBook Air 2018款支持通过雷电3外接图形处理器（eGPU），但是不清楚是不是要用那种雷电3显卡扩展坞搭配使用，再说在macOS系统下也没啥游戏可以玩，这个功能是不是鸡肋就不在这探讨了。
看了一下MacBook Air的成色的确是蛮好的，不存在明显肉眼可见大面积磕碰凹陷、挤压变形的情况。
之前的键盘上油脂太明显了，拿消毒水和湿纸巾仔细的擦拭才显得这么干净。当然这个macOS系统是我后面帮哥们重装的。
苹果MacBook Air模具可以用几年也的确是耐看，只要舍得花钱用CNC工艺做出的机身肯定质感是很不错的。
MacBook Air 2018款的屏幕上还是明显有一些涂层脱离，但并不影响使用体验。
这个是MacBook Air 2018款的触控ID按键，带有Touch ID。
这个是屏幕开启最高亮度下的显示效果，不愧是买屏幕送电脑的苹果啊。
重装macOS Venture（macOS 13.2.1）系统
制作好了macOS Ventura系统USB引导盘，开机按下Option键后即可看到：Install macOS Ventura。
默认情况下Mac电脑都是安全设置不允许使用外部启动盘，需要关掉这个功能才能重装系统。
修改启动安全性实用工具，输入macOS密码后解锁。
在安全启动中选择：无安全性，在外部启动中选择：允许从外部介质启动。
进入macOS系统安装界面。
如果按下解锁没有用的话，提示请解锁“Macintosh HD”无反应的时候，那就只能对固态盘做初始化了。
直接抹掉固态盘重装系统就行了，按图设置文件系统格式：APFS，方案：GUID分区图。
开始安装macOS Venture（macOS 13.2.1）系统。
这个是重装后的macOS系统，当前版本：macOS Ventura 13.2.1。
macOS Ventura（macOS 13.2.1）系统信息
MacBook Air 2018款的硬件配置：1.6GHz双核Intel Core i5处理器，Intel UHD Graphics 617集成显卡，8GB 2133 MHz LPDDR3内存，128GB固态盘（重装系统后默认可用空间：104.18GB），Retina（视网膜）13.3英寸IPS屏，分辨率：25601600。

MacBook Air的保护袋
既然是哥们送给他的女朋友，购买了一个MacBook Air专用的保护袋，粉色的女孩子们肯定会很喜欢吧。
总结
这也是目前能够体验到最新macOS系统的MacBook Air了，整体硬件性能的确是比较落伍的。而且苹果对于小容量固态盘在写入速度只能说很一般，也就是读取速度还凑合吧，要问到底值不值得买，这个价位肯定是很值的入手啊。

邱录狄2393大家,这个机器码怎么改,重装了系统还是不会变 -
禹瑾党18615222193 ______ 机器码是根据电脑的硬件(主板)信息经过一定公式运算而自动生成的的一组数字,您可以在软件的“软件注册”、“关于软件”或者“软件版本信息”等对话框中进行查看.每台电脑对应一个机器码,每个机器码对应唯一一套软件序列号和注册码. 在电脑硬件(主板)不变的情况下,软件的机器码会始终保持同一个值,即使在以下操作时都不会发生改变.如: 硬盘重新分区、低级或者高级格式化; 重装、改装操作系统或者安装多系统; 更换或者添加硬盘. 特别注意:相同型号电脑有可能会生成相同的机器码,相同的机器码可以使用同一套软件序列号和注册码进行注册.用户在购买多套软件序列号和注册码之前请务必在多台电脑中安装软件查看机器码,统计正确的机器码数量.
邱录狄2393会计题库有机器码重装系统时有没有影响 -
禹瑾党18615222193 ______ 你好,一点通网校回答你的问题 应该是一机一码方式吧,重新安装,机器码应该没有什么变化.
邱录狄2393电脑更换系统会改变软件的机器码吗? -
禹瑾党18615222193 ______ 不会的,一个硬件只有一个独立的ID,不管系统如何更换,都不会影响硬件的ID,除非有些软件可以修改,不过也是修改你看到的,机器码还是不会变
邱录狄2393修复系统,会改变机器码吗? -
禹瑾党18615222193 ______ 应该改变不了的,机器码是硬件的一种标识.
邱录狄2393网上购买的exe教学视频,现在要重装系统,请问重装后机器码会不会变化?原来的机器码和密码是不是没用了? -
禹瑾党18615222193 ______ 一般情况下机码是可以的 不过楼主重新安装系统就不太行了 因为机码是你当前系统配置 换系统或配置不太行
邱录狄2393哪重装系统和换硬盘会不会改变机器码 ? -
