windows破解教程(转载自https://www.cnblogs.com/xiaoming0601/p/12304947.html)
- 首先下载jar包：（云盘链接发不上去，大家关注gzh"灰太狼学爪哇"回复idea获取）将其放到合适的文件夹（首选IDEA的同级目录）进行管理；
- 进入C盘 —> 用户 —>用户名 —> .IntelliJIdea2019.2或者.IntelliJIdea2019.3 —> config —> idea64.exe.vmoptions文件，在文件的末尾加上-javaagent:jar路径和jar包名字，例如-javaagent:D:IdeajetbrainsCrack.jar，然后关闭打开的文件；（如果C盘没有vmoptions文件，试试去安装目录根目录下的/bin文件夹下找找试试）
- 打开IDEA，这个时候因为是未激活，所以会弹出激活验证的窗口、选择Activation Code，下方会让你填写密钥，填写下方密钥

检查是否激活：IDEA界面 —> help —> About，一般是激活到期至2089年
有反馈说按照教程配置修改完后，填写注册码还是会报错失效，这里再教大家一个方法，就是通过选择“License Server ”方式激活，填写如下链接：（当然，前面的步骤还是不能少）
http://jetbrains-license-server
MAC系统激活教程
其实原理都一样，就是在vmoptions文件里面制定-javaagent路径就可以了，但是由于mac的特殊性，对应的目录不容易找到。
mac中对应的要修改文件的名称是idea.vmoptions，有些人很聪明，直接找到了idea的安装目录下的idea.vmoptions文件，比如我对应的目录是：
/Applications/IntelliJ IDEA.app/Contents/bin/idea.vmoptions
结果修改完成后，还是没有用。
在这里我要纠正一下，idea启动读取的不是上面/bin目录下的文件，而是另外有一个文件，这个文件在一个叫做“/Library”资源库的隐藏文件夹下面，在我电脑上对应的路径是：
/Users/username/Library/Preferences/IntelliJIdea2019.3/idea.vmoptions
而进入到这个隐藏文件夹的方式就是：
1.打开finder
2.点击上面菜单栏的"前往"，与此同时按住“option”按键，隐藏的“资源库”就出现了
3.进入到我上面给的目录下面，找到idea.vmoptions就可以了
后面修改的过程，同windows。
结果如下：
激活成功，可以用到2089年了
