本来看网上已经有写的不错的教程，结果用起来的时候发现有一些问题，首先是版本号的问题，另外是文件路径问题，还有就是碰到的修改hosts没有权限问题，还是想着记录一下，方便需要的童鞋使用。
如果发现什么问题，请及时联系我。

首先要谢谢各位大神的分享。
不过也还是请大家多多支持正版，https://www.jetbrains.com/idea/buy/；
破解步骤：
1.下载安装IDEA，我下载的版本是2018.2.7，下载地址：https://www.jetbrains.com/idea/?fromMenu；
想要选择历史版本的话，就点击左侧下方的previous versions链接，进入版本选择界面https://www.jetbrains.com/idea/download/previous.html；
2.这里下载激活包：http://idea.lanyus.com/，我是下载的这个版本http://idea.lanyus.com/jar/JetbrainsCrack-2.10-release-enc.jar；
3.添加 0.0.0.0 account.jetbrains.com到hosts文件中，/etc/hosts，直接修改的话会报无权限，需要复制到桌面，然后修改添加成功之后，再拖回来直接替换即可。
4.在finder新建/Library/路径下的 JetbrainsLicense文件，将其放进去；
5.打开安装文件夹的bin文件中的idea.vmoptions 在最后一行加入：
// 这里其实就是 -javaagent:(jar文件的路径) 建议不要直接复制
-javaagent:/Library/JetbrainsLicense/JetbrainsCrack-2.10-release-enc.jar

6.打开软件，然后看到界面如下：
