Unable to transfer EOS R5 Mark II firmware update to card

[Scubachuck]

Trying to update R5M2. First time went without issue. Now I’m unable to transfer the .fir file to my card. I’m using the correct operating system, Mac. l know to put it in the root. I’ve tried both cards. 
what am I missing? Thanks

That’s exactly what I do, but the .fir file just bounces off the card icon.

John,

Thankyou for your help. 
I just drag it to the card, not to any folder. It just bounces back.

You said CF card. I am assuming CFExpress based on camera model. I am not aware of any locking feature for those cards. If it was an SD card there is a lock. 

Edit- Deleted. I misread camera model.

There is 1 SD card and 1 CF express. But you thought was perfect, I never would have thought of it. No on and off switch. I did write to Angelbird to  ask them if they had an idea. I will let you know. 
I really appreciate your help. I’m 8o and things don’t come quickly any more

That’s exactly what I do. The file does not download to the card when I drag and drop. 
I just wrote to Angelbird to ask them if they know what’s going on. The cards work when I take a photo so they should be a problem. 
‘Thanks for helping.

John,

I thought that I would tell you the solution. I’m not real bright. I wrote to Angelbird and asked them. My card and reader are Angelbird. On the reader there is a very tiny switch that prevents writing on the card. That was on. I turned it off, everything worked. 
‘Thanks for all your effort.

Glad it worked out. I never saw that feature on other card readers. It would be easy to miss. Select Solved so others don’t chime in. Happy Holidays to you as well.

Best to stay sway from it. It ruined mine. I'm so angry about it. It was doing good with AF and not it wont lock on to any moving object.
