installed appium-1.5.3.dmg But when I click the stethoscope button the Appium is show error :

✔ Xcode is installed at: /Library/Developer/CommandLineTools

[Error: Could not detect Mac OS X Version from sw_vers output: '10.12

']

You can config file by this command:

grep -rl "Could not detect Mac OS X Version from sw_vers output:" /Applications/Appium.app/

Terminal will show :

/Applications/Appium.app//Contents/Resources/node_modules/appium/node_modules/appium-support/build/lib/system.js

/Applications/Appium.app//Contents/Resources/node_modules/appium/node_modules/appium-support/lib/system.js

/Applications/Appium.app//Contents/Resources/node_modules/appium-support/build/lib/system.js

/Applications/Appium.app//Contents/Resources/node_modules/appium-support/lib/system.js

手动将文件修改例：
