It's small and hard to see.
* No. 1, it seems that I have to change the character string in the text box of item "Bundle identifier".
This time it was originally `org.byteball.wallet`,
I set it up as `org.byteball.mun` and survived.
This character string Anything is fine.

* Next, I emphasized No. 2 red. Open the drop-down menu of Team items and select your account as it should be there.

* I'd like to install ByteBall's app Connect the handheld iPhone to your Mac. Then I wait for a while because I load variously like various loads.
