How to notarize a Unity build for macOs 10.15 Catalina

As of January 2020, all apps running on macOs 10.15 Catalina are required to be notarized. For Unity games distributed outside the Mac App Store, such as with Steam, the notarization process is done post build using a series of Xcode command line tools.

Prerequisites

• a Mac that is compatible with macOs 10.15 Catalina :
  • MacBook (2015 or newer)
  • MacBook Air (2012 or newer)
• MacBook Pro (2012 or newer)

It's relatively easy to just put the Loomo and PC on the same wifi network, start a ROS master on the PC, and pass messages.
But it's preferable to have a hard-wire connection between the two devices, since it should be faster and more relibale than WiFi.
In particular, we will use USB tethering from Android->PC in these instructions.
Note: This method allows the ROS master to be set either on PC or Android! And no root access needed on Android.

--------------------------------------------------

Switch Loomo into Developer Mode (Settings > System > Loomo Developer > Developer Mode)
    - (I think this requires an internet connection, so join a wifi network now.)
You might need to switch Android into Developer Mode (tap some setting 7 times...look online for instructions).
