Something I’m not seeing in your first sketch is where you declare what chipselect pin for the SD card. On the Mayfly it’s 12, so on line 42, change the “SS” to “12”. Then remove all the extra Serial.begin(9600) statements so there’s only one at the beginning of the setup function. And remove the RTC stuff on lines 11, 16, and 41. See if that will write the data to your card.
