Lately, when I am in SL, the Python icon in my dock keeps popping in and out, as if I need to do something with it. Later, when I log out, I receive a message: "Please find a system admin to upgrade Second Life." I honestly have no idea what to do, or if I need to do anything. I don't know how to "find a system admin." SL seems to work all right. I have recently upgraded to MacOS Mojave, and it did not stop the message or the Python icon. I have tried Safari and Chrome browsers.
