Hey everyone! I’m trying to move some documents and books directly from my Kindle Colorsoft onto my MacBook, but I’ve hit a wall. When I plug the Kindle in, Calibre doesn’t detect it at all, and nothing shows up on my Mac.
Your Kindle Colorsoft probably isn’t broken. The issue is that 12th-generation Kindles connect through MTP (Media Transfer Protocol) rather than appearing as regular USB storage. macOS doesn’t handle MTP natively, so neither the Mac nor Calibre can see the device normally.
Amazon’s official Send to Kindle app for Mac is one option. You can download the installer from Amazon, then use its USB File Manager, drag files into the app, or send them by right-clicking in Finder.
If you want the Kindle mounted for direct file transfers, you’ll need an MTP app such as MacDroid or OpenMTP. I haven’t personally tested every option, but OpenMTP gets recommended fairly often for the Colorsoft. This thread covers using it with Calibre on a Mac: https://www.reddit.com/r/Calibre/comments/1hob59w/calibre_and_kindle_colorsoft_on_mac/.

Moving your own PDFs or EPUBs is fairly simple with an MTP tool like MacDroid, while copying Amazon-purchased books back to the Mac may fail because those files can be DRM-protected. There’s no hidden USB setting to change, but use a data-capable USB cable and unlock the Kindle before connecting.
You won’t get a complete Kindle backup by dragging its folders onto the Mac.
For your own PDFs, EPUBs, and other sideloaded documents, install an MTP client such as MacDroid, connect the Colorsoft with a data-capable cable, wake and unlock it, then copy the files from the visible documents folder. There is no USB mode menu on the Kindle that turns it into a normal external drive.
Make sure only one transfer app is running. MTP programs can compete for the same connection, so quit OpenMTP, Android File Transfer, Calibre, or similar tools before trying MacDroid. If the Kindle still does not appear, swap the cable first. Plenty of USB-C cables supply power but do not carry data.
The bigger caveat is what “Kindle files” means. Personal documents should copy normally. Amazon-purchased books may be DRM-protected, and copying their files to macOS does not necessarily produce books you can open, import, or use as a backup. Collections, reading position, and other library information may not come across with the book files either.
For that reason, I’d keep the original copies of personal documents on the Mac and treat the Kindle as the destination, not the only storage location. Use MTP when you genuinely need to retrieve a sideloaded file, and use Send to Kindle when you only need to put a document onto the Colorsoft. Eject or disconnect it through the MTP app after the transfer rather than pulling the cable during a copy.
Don’t pay for an MTP app until you know the cable and connection work. Try a free option such as OpenMTP first. If it detects the Colorsoft after you wake it and unlock the screen, you’ve confirmed that macOS’s lack of native MTP support was the problem. There is no Kindle USB setting you need to enable.
Copy files to the Mac rather than moving them, then open a few before deleting anything from the Kindle. Sideloaded PDFs and EPUBs should be straightforward, but filenames can be messy and Amazon books may be encrypted or split across supporting files. As @pete_git said, copying the visible folders is not a reliable full-device backup.
If OpenMTP is unreliable on your Mac, MacDroid may be easier, but close every other app that could access the Kindle first. Finder will not mount the Colorsoft like an ordinary flash drive, so waiting for it to appear under Locations usually goes nowhere.
Don’t keep installing transfer apps until you know the Mac can see the Kindle at the USB level. Hold Option, open the Apple menu, choose System Information, then check Hardware > USB. If the Kindle is absent there, change the cable, connect directly instead of through a hub, and approve the accessory if macOS prompts you.
If it appears in System Information, the hardware connection is fine. Quit every MTP utility and open Amazon’s Send to Kindle USB File Manager by itself. It can browse the Colorsoft and copy files in either direction, even though Finder never mounts the device.
That test saves a lot of guesswork: invisible in System Information means cable, port, or permission trouble; visible there but missing from the file manager means a software conflict. There is no USB mode on the Colorsoft that you need to hunt down. Copy your documents to the Mac first and verify them before deleting anything.
Copying a title off the Colorsoft may leave you with a device-format file that is useless on the Mac, even though the transfer itself succeeded. The USB connection only exposes stored files. It does not convert Kindle book files into EPUBs or create a portable library.
I wouldn’t involve Calibre until the files are already on the Mac. Open the Colorsoft with Amazon’s USB File Manager or an MTP client, copy the contents you need from the Documents folder into a normal local folder, then inspect the extensions. PDFs and your original DRM-free documents are usually straightforward. AZW, KFX, and folders containing several supporting files are likely Kindle-specific content and may not open independently. Amazon confirms that newer Kindle models require a separate Mac application for USB browsing rather than appearing in Finder.
For purchased books, check Manage Your Content and Devices before extracting anything from the Colorsoft. Since January 20, 2026, some verified purchases can be downloaded directly as EPUB or PDF when the publisher has confirmed the title is DRM-free. That gives you a much cleaner file than copying the device version. It does not apply to DRM-protected titles or Kindle Unlimited loans, and many older books will not offer the option.
There is no USB mode to enable. If the Kindle appears under USB in System Information, as @its_tiger described, the hardware connection works. At that point, run exactly one MTP application, copy rather than move, and verify the files on macOS before deleting anything from the Colorsoft.
Everyone’s deep in MTP tools, but your Amazon purchases already sit in your account online, so there’s no reason to drag those off the device anyway. MacDroid or OpenMTP only matter for the sideloaded stuff you don’t have another copy of. If it’s just your own PDFs and EPUBs, grab them once, verify they open, and stop treating the Kindle as a backup.
Don’t start a large copy and let the MacBook go to sleep. MTP transfers are less forgiving than copying from a normal external drive, and an interrupted batch can leave you unsure which files transferred correctly. Keep the Mac awake and copy into a new folder in smaller groups.
For a few documents, Amazon’s USB File Manager is the simpler choice. For browsing lots of folders, OpenMTP gives you something closer to a two-pane file manager, though it still will not make the Colorsoft appear in Finder. A paid tool like MacDroid mainly buys convenience, not a different kind of access.
Think of MTP as an app-controlled copy session rather than a mounted disk. You do not need to change a USB setting on the Kindle. Use a data cable, unlock the device, run only one transfer program, and copy rather than move. Then compare file counts and open several PDFs or EPUBs on the Mac before removing anything from the Kindle.
Before you install anything, ask yourself whether the files on that Kindle exist somewhere else already. If you sideloaded those PDFs and EPUBs from your Mac in the first place, the copies on your drive or in your email are the real originals, and pulling them back off the Colorsoft is just extra work. The only time MTP is genuinely worth the hassle is when the Kindle holds the only copy of something.
On the tool question, @nextcraft5726zone has the right order. Try OpenMTP first, confirm the device shows up, and only reach for MacDroid if OpenMTP acts flaky on your machine. MacDroid is fine and it does give you a cleaner two-pane transfer, but it’s a paid convenience layer over the same MTP access, so don’t buy it until you’ve proven the cable and connection actually work. Otherwise you’re paying to discover a dead cable.
The part nobody’s really flagged is how the Documents folder looks once you’re in there. Kindle doesn’t store books as tidy named files. You’ll see stripped filenames plus separate.sdr folders holding sidecar data like annotations and reading position. So when @0xsprite5 says collections and reading position may not come across, that’s the reason. You’re copying raw storage, not a library that knows how to reassemble itself.
Realistic expectation: for your own DRM-free PDFs and EPUBs this is a five minute job, messy filenames aside. For anything from Amazon, checking Manage Your Content and Devices like @gadget.ai suggested beats fishing device files off the Kindle every time. Copy into a fresh folder, open a couple before deleting a thing, and don’t let the Mac nap mid transfer.
