  1. If you want to format your SD card on Mac, choose ExFAT as your formatting tool.
  2. If you find the desired formatting tool for your flash drive or external drive, you will likely go with APFS.

When you need a formatted hard drive on Mac in conjunction with Time Machine, then Mac OS X Extended would be the only option to go with the process because the Time Machine is unfamiliar with the APFS formatting system. Also, if you try to access APFS on Time Machine, you must use the reformat option.
