问题

当我点击最下面任务栏的idea图标，跳了一下之后就再也没反应了

什么提示也没有，咱也不知道啥问题啊，但是咱会百度啊，百度说是让我点进去应用程序 —> 在idea上右击-> 显示报内容

进入包内容后，双击 Comtents/MacOs/idea文件，

然后会在控制台打印一连串的信息

我们重点关注这一行：
Error opening zip file or JAR manifest missing : JetbrainsCrack-3.1-release-enc.jar.
这一行代码是告诉你出现问题出在哪，告诉我们找不到这个jar打开失败了，或者是这个jar根本就不存在，但是我们根本就没用过这个jar包；并且上面也告诉我们是在哪个文件报错了：
2021-07-13 10:07:06.768 idea[1409:27636] Processing VMOptions file at /Users/mac/Library/Application Support/JetBrains/IntelliJIdea2020.2/idea.vmoptions
所以我们直接打开/Users/mac/Library/Application Support/JetBrains/IntelliJIdea2020.2/idea.vmoptions这个文件，输入命令：

vim /Users/mac/Library/Application Support/JetBrains/IntelliJIdea2020.2/idea.vmoptions

可以看到最后一行多了个 -javaagent:JetbrainsCrack-3.1-release-enc.jar，这是我之前破解文件用过的jar包，但在这里我们已经用不到了，所以将其删除；

删掉之后idea就可以打开了
