Kiindle Fire doesnt show up on MacOS Big Sur

[silsurf]

I should have posted this here instead of the Kindle Fire forum.

I been trying to get my Kindle Fire to show up on my new iMac running Big Sur and Calibre. I followed the comments and ideas on a thread here and assume it was a cable issue. I have had difficulty with some USB devices mounting. I bought an Amazon basics Amazon Basics Fast Charging USB-C2.0 to Micro-B Cable but still the unit does not show up in Calibre. It is charging and says it is in USB mode, but have yet to get Calibre to see it.

It was also recommended to makesure to toggle the MTP mode each time I plug the Kindle in. The only way to see the MTP mode toggle is to tap on the USB icon in the upper left corner of the screen once a USB device is plugged in. The mode is selected to MTP, but the kindle still does not show up in Calibre? There is also a triangle with a "!" in the upper left corner and when I tap that a dialog box says:

"USB Compatibility
Some computers require a free file transfer utility yo copy files between the computer and your Fire. If you need this utility go to kindle.com/support/downloads..."

If I navigate to this address, there is just an Amazon search bar and support files, no specific software. I am assuming Calibre is the software in question, but the Fire still does not show up as it used to on previous versions of MacOS

Any guidance appreciated

MTP devices are not mountable in macOS. They use the MTP protocol. Make sure you have turned on the MTP mode in the device before starting calibre. Then start calibre, if the device doesn't show up follow the steps in https://manual.calibre-ebook.com/faq...ted-by-calibre
