首先打开Android studio包，进入MacOs,运行studio，可以出现运行信息

Error occurred during initialization of VM //II 错误信息
Initial heap size set to a larger value than the maximum heap size
II、 VM初始化期间发生错误，初始堆大小设置为大于最大堆大小的值
于是我们只要找到初始化堆大小的位置和最大堆大小的位置，将这两个值中的一个调整一下就好了。而VM的相关配置信息在VMOptions对应的文件中。从运行信息中可以看到有两个文件分别是：
/Applications/Android Studio.app/Contents/bin/studio.vmoptions
和
/Users/【youUserName】/Library/Preferences/AndroidStudio3.5/studio.vmoptions
由于不知道运行的是哪个配置文件，所以最好就两个都改，其中：
-Xms //初始化堆大小
-Xmx //最大堆大小
只要让-Xms的值小于-Xmx的值就可以了。
