Select ... uh MacOS... does it show a menu bar somewhere? Maybe if you press alt or the CMD key? There should be something called File or similar and Receiving address below that. The same menu should allow you to make a backup, consider making one (encrypted!) after you have send the coins. Just in case.


It will list all your addresses and allows you to generate a new one. It also has a copy button, select an address and hit the copy button to get it into the clipboard.

To send the bitcoins to that address from bitgo you can use their step by step guide here [1].
