Arduino MKR Zero not writing data to sd card after unplugging from computer

Well, I'm an idiot.
It may not be the prettiest solution but in all of my searching nobody has actually posted a solution for the MKR Zero. It appears to be a simple timing issue. A delay(xxx) won't work, but a simple for() loop does the trick. It allows the micro to run and finish initializing the Serial, but doesn't actually require a computer connection to monitor the serial. This allows the MKR Zero to be powered by a USB cable (from a power supply of your choice) and NOT connected to a computer.
Solution = Replace the "while(!Serial){}" with a for() loop.
Example:

void setup() {
  Serial.begin(9600);

  // while (!Serial) {
  //   ;  // wait for serial port to connect. Needed for native USB port only
  // }

  for (int i = 0; i <= 10000; i++) {  // Eliminates the need for the "while (!Serial){}" above.
    ;
  }
