Ok, first of all you need to download appium for Mac OS, then you need to setup dev project and build code on your machine, under product folder in dev project you will see file.app just copy file path and add it to appium caps, then add all caps you need
platformName
platformVersion
deviceName
udid
app
and enjoy to inspect all elements.
to automate your app just write your code and add caps same above, and initialize your appium driver from code.
Thanks,
