I'm trying to update the firmware on a Nikon Coolpix B500. I'm using a new memory card. I have tried formatting the card in the camera first. Then I put the downloaded folder on the card. I've also tried just putting the .bin part on the card. The camera does not ask whether we want to update or not. I've also erased the memory card and started over just putting the file on the card and then into the camera. Still doesn't ask if we want to update. I'm using a Mac. I've checked the card using disk utility, and it says it is a FAT file. Not sure what else to try. Any suggestions?
According to the Nikon instructions, after putting the firmware folder (created when you installed the downloaded dmg file) onto the memory card and turned the camera on-
Select Firmware version in the Set up menu and follow the on-screen instructions to complete the firmware update.
