⼩⽶笔记本装MAC（⿊苹果），外接USB蓝⽛，禁⽌笔记本⾃带
的蓝⽛⽅法
1、⼩⽶笔记本装⿊苹果10.13后，⾃带的intel蓝⽛不稳定，想要⽤⿏标键盘⽹上说⽆解。
2、购买USB蓝⽛4.0在某宝上20多元，但是因为mac为了保证⽤户体验只⽀持1个蓝⽛设备，所以直接插上USB蓝⽛不能使⽤，需要禁⽤⾃带的蓝⽛。（信息是卖家提供的）
3、我再此记录禁⽤⼩⽶笔记本Pro 装⿊mac禁⽤⾃带蓝⽛的办法
3.1 到⽂件：/System/Library/Extensions/IOBluetoothFamily.kext
3.2 到⾃⼰的蓝⽛硬件⼗六进制的“供应商ID”和“产品Id”，“关于本机”->"系统报告"->“蓝⽛”  ，我的是0x8087 ,0x0A2B
3.3 将蓝⽛的⼗六进制转成⼗进制，即8087->32903      0A2B->2603
3.4 IOBluetoothFamily.kext 右键->显⽰包内容->Contents->PlugIns->BroadcomBluetoothHostControllerUSBTransport.kext->显⽰包内容->Contents->Info.plist，⽂本⼯具打开Info.plist
3.5 将所有的idProduct、idVendor值进⾏替换，⽬的是禁⽌该设备
<key>idProduct</key>
