Typora

实在太好用，突然不能用，就堪称灾难。

曲径通幽…默。各种找料理妙招，最后发现特简单：Trouble Shooting - macOS

macOS

Cannot open / input on macOS 10.15

Please refer #2923, cleaning existing config / cache of Typora using 3rd app such as AppCleaner, and then restart Typora will get everything working again.

Cannot save / close / quit / export on macOS 10.15

Please refer #2895, cleaning existing config / cache of Typora using 3rd app such as AppCleaner, and then restart Typora will get everything working again.

简而言之，把 Typora.app 拖进 AppCleaner 然后把找到的文档全都清理掉（ Typora.app 及其他可能乱入者除外），然后重新打开 Typora 就好了。

没装 Typora 和 AppCleaner ？装吧：

brew cask install typora appcleaner

更新后 Typora 不能用了，咋整？
