Kindle Scribe Not Connecting to Mac via USB – Any Fix?

I’m trying to connect my Kindle Scribe to my Mac using a USB cable, but it’s not being recognized. I was hoping to transfer PDFs and notes directly, but Finder doesn’t show the device at all. I’ve tried different cables, restarting both devices, and even checking for software updates, but nothing seems to work.

Does the Kindle Scribe require a special setting or driver for Mac? If anyone has figured out a reliable way to connect and transfer files, I’d really appreciate the help.
Thanks!
