布鲁诺是正确的。我已经进行了广泛的研究，如果您想设置所有GUI应用程序中都可用的变量，则唯一的选择是/etc/launchd.conf。

1. 打开终端提示

2. 类型sudo vi /etc/launchd.conf（注意：此文件可能尚不存在）

3. 将如下内容放入文件中

# Set environment variables here so they are available globally to all apps
# (and Terminal), including those launched via Spotlight.
#
# After editing this file run the following command from the terminal to update
# environment variables globally without needing to reboot.
# NOTE: You will still need to restart the relevant application (including
# Terminal) to pick up the changes!
# grep -E "^setenv" /etc/launchd.conf | xargs -t -L 1 launchctl
#
# See http://www.digitaledgesw.com/node/31
# and http://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x/
#
# Note that you must hardcode the paths below, don't use environment variables.
# You also need to surround multiple values in quotes, see MAVEN_OPTS example below.
#
setenv JAVA_VERSION 1.6
setenv JAVA_HOME /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
setenv GROOVY_HOME /Applications/Dev/groovy
setenv GRAILS_HOME /Applications/Dev/grails
setenv NEXUS_HOME /Applications/Dev/nexus/nexus-webapp
setenv JRUBY_HOME /Applications/Dev/jruby

setenv ANT_HOME /Applications/Dev/apache-ant
setenv ANT_OPTS -Xmx512M

setenv MAVEN_OPTS "-Xmx1024M -XX:MaxPermSize=512m"
setenv M2_HOME /Applications/Dev/apache-maven

setenv JMETER_HOME /Applications/Dev/jakarta-jmeter

1. 在vi中保存所做的更改，然后重新启动Mac。或使用上面的代码注释中显示的grep/xargs命令。

2. 通过打开“终端”窗口并键入来证明您的变量正在工作，export并且您应该看到新的变量。这些也将在IntelliJ IDEA和您通过Spotlight启动的其他GUI应用程序中提供。
