问题：2009年制Apple A1314键盘，经常有两三个数字键会随机自动连击，重複輸入。
打开键盘帽清洁后，没有修复。故应属电路板故障。
解决方案：①拦截数字键 ②按住fn后可输入数字键
下载并安装Karabiner-Elements
安装完成后，在Mac设置软件权限
确认 A1314 的设备 ID
Karabiner → Devices
・Vendor ID：1452
・Product ID：599
・Product ID：599
※ 注意是「外接键盘」的ID
用TextEdit制作规则文件
① 打开 TextEdit
Command + 空格：TextEdit
切换为纯文本模式(Shift + Command + T)
