Help with SD card issue/firmware

[Serenity]

Hi there flyers, first post, I have a possibly very dumb question driving me crazy.

Want to update my firmware, I think I understand the whole process but can't get past "copy the .bin file to your SD card." The card will not accept or read the bin file, a 'no go' symbol comes up and it won't transfer.

I am on Mac, have flown and used the SD card many times. I formatted the SD card in my quad, downloaded the firmware zip file from DJI, open that and see the .bin file.

But when I try to copy or drag the .bin file onto the formatted SD card (in fat32), it won't accept it so I can't even get started.

I've read and watched videos of people casually dragging the .bin file onto the SD card, but it just won't do it and I don't know why at all.

Thanks for any help, seems like something real simple I'm missing.

And apologies if its been covered, I searched many threads about firmware updates and couldn't find the issue i'm having, seems it's the easiest step in the process.

Look for a small sliding lock on the side of the SD card adapter.
It might be in the locked position?

Just checked, adapter is not in the locked position.

It's very odd, same memory card I've used many times. I'm stumped.

I got it, as I thought was something very simple.

I have a multi-card type reader, there is a slot for uploading only and a slot for transferring files apparently, I had no idea.

Cool forum, happy flying.
