When I try to save a file from cura to the ultimaker SD-card it gives this error.

Card is not locked by the lid.

I tried both Mac and windows.

How can I transfer a file to the SD card?

I'd get another SD card.

Are you sure you don't have lock/unlock backwards regarding the little switch on the SD card?

try it multiple times, again and again, I have several cards with the same issue, or use an usb/sdcard extension.

Thanks, I figures out the problem.

The cars was connected to the PC with a card reader..

Direct plugged in SD card worked fine.

Card reader, is what the name indicates, just a reader I think.
