Kindle Not Showing Up on Mac: macOS Has No MTP Driver

Q: Does Amazon's USB File Manager work on M4 Macs?

Amazon lists only Intel and M1 to M3 Macs running macOS 12 or later. The USB File Manager app and its libraries are x86_64-only code, so on every Apple silicon Mac, including M4, it runs through Rosetta 2, which macOS prompts you to install. Apple keeps Rosetta as a general-purpose tool only through macOS 27.

Q: Is Android File Transfer still available for Kindle on Mac?

No. Google discontinued Android File Transfer, and android.com/filetransfer now redirects to a Quick Share page for Windows. The remaining USB options for MTP Kindles on a Mac are OpenMTP, calibre and the USB File Manager in Amazon's Send to Kindle app.

Kindle not showing up on Mac, but it charges? On any Kindle released in 2024 or later, and on the Kindle Scribe since its 5.16.3 firmware, that is expected behaviour rather than a fault. Those models talk to a computer over MTP (Media Transfer Protocol) instead of presenting themselves as a USB drive, and macOS has no MTP driver. Windows mounts them; Finder never will. Older Kindles still show up as a drive, so if yours is older, something else is in the way.

I don't own a Kindle. What I could check was the Mac side: what macOS 26.4.1 ships on our Mac mini M4, and what's actually inside the installer Amazon offers as the fix. That second check turned up something the help page leaves out: Amazon's USB File Manager is Intel-only code. On an Apple silicon Mac it runs only through Rosetta, and Apple has put an end date on Rosetta.

Which Kindles show up in Finder

Amazon's own help page, Connect, Browse, and Transfer Files on E-Reader, draws the line in one sentence: "Kindle Scribe and 2024-released Kindle devices require a separate application" on a Mac, while "models released earlier than 2024 (except for Kindle Scribe) don't require a separate application." I filled in the dates from owner threads:

Kindle	USB mode	On a Mac	Source
E-readers released before 2024 (Basic, Paperwhite 11th gen and older, Oasis)	USB mass storage	Mounts in Finder as "Kindle"	Amazon help page
Kindle Scribe (2022)	MTP since firmware 5.16.3 (Aug 2023)	Needs an MTP app	MobileRead thread
2024 releases: Kindle, Paperwhite 12th gen, Colorsoft, Scribe	MTP	Needs an MTP app	Amazon help page
Models released after 2024	Not named by Amazon	Assume MTP; Amazon only exempts pre-2024 models	Inference, unverified

The open-source MTP library most Mac tools build on keeps a table of known devices. In libmtp's music-players.h there are 39 entries under Amazon's USB vendor ID 0x1949. Thirty-eight are Fire tablets. The only e-reader is "Kindle Scribe 32GB", added on 2023-11-24 after an owner reported it as UNKNOWN. E-reader MTP on the desktop is that recent.

What macOS 26 actually ships

On the Mac mini (Mac16,10, macOS 26.4.1 build 25E253) I listed the kernel extensions and DriverKit extensions. IOUSBMassStorageDriver.kext is there, which is why an older Kindle mounts like a thumb drive. No extension handles MTP. The closest thing is /usr/libexec/ptpcamerad, the daemon behind Image Capture. It contains MTP property calls ("Device supports PTP1.1/MTP1.0 enumeration"), but it exists to pull photos off cameras. It never gives Finder a volume with a Documents folder in it.

This is the same situation as a USB Wi-Fi adapter on a Mac: the hardware is fine, Apple ships no class driver for it, and the only fix is an app that brings its own.

Amazon's fix, unpacked

Amazon's answer is the USB File Manager inside its Send to Kindle app. The help page says it "works with Intel and Mac M1-M3 computers with MacOS 12 and above." That list has no M4 on it, and ours is an M4, so I downloaded the installer and opened it without installing:

$ pkgutil --check-signature SendToKindleForMac-installer.pkg
   Status: signed by a developer certificate issued by Apple for distribution
   Notarization: trusted by the Apple notary service
   Signed with a trusted timestamp on: 2026-03-06 06:55:22 +0000
$ pkgutil --expand-full SendToKindleForMac-installer.pkg x
$ lipo -archs "x/.../USB File Manager.app/Contents/MacOS/USB File Manager"
x86_64
$ lipo -archs ".../Frameworks/libKindleDocsExternalMtp.dylib"
x86_64
$ /usr/bin/arch -x86_64 /bin/ls
arch: posix_spawnp: /bin/ls: Bad CPU type in executable

Package 1.1.1.260, signed in March 2026, and every binary in USB File Manager.app is x86_64 only: the app and its four bundled libraries. The MTP library carries libmtp's function names and the version string 1.1.21, libmtp's April 2023 release, alongside a copy of libusb. The last command shows that Rosetta isn't installed on our Mac at all, so here the app would stop at macOS's Rosetta install prompt before it ever looked for a Kindle.

That probably explains Amazon's "M1-M3" wording better than any hardware limit does. The real constraint is Apple's own Rosetta documentation, which says Rosetta stays available as a general-purpose tool through macOS 27 and is then reduced to a subset aimed at older games. I ran into the same deadline in the 3D printer slicer census, where all eight slicers had native builds. Amazon's file manager doesn't, and the help page doesn't mention it.

Diagnose it in three checks

The first check splits hardware problems from protocol problems. Only the bottom-right branch needs extra software.

1. Is the Kindle on the USB bus at all? Plug it in, wake the Kindle's screen, and run:

system_profiler SPUSBHostDataType | grep -i -B2 -A8 kindle
ioreg -p IOUSB -l -w0 | grep -i -A3 '"idVendor" = 6473'   # 6473 = 0x1949

On macOS 26 the old SPUSBDataType name prints nothing, which I covered in lsusb on Mac. If neither command finds the Kindle, macOS never saw it, and no software will fix that. The usual cause is a charge-only cable, and telling USB-C cables apart is harder than it should be. Try the cable that came in the box, plugged straight into the Mac rather than through a hub. On an Apple silicon MacBook there is one more gate. Apple's accessory approval page says a new USB device needs you to click Allow, and that "accessories can still charge your Mac (or themselves) even if you choose Don't Allow." A Kindle that charges but never appears fits that exactly. Check Privacy & Security > Accessories in System Settings.

2. Listed, and released before 2024? Then it's a mass storage device and should mount. If nothing appears on the desktop, check Finder > Settings > Sidebar > External disks, and look in Disk Utility for an unmounted volume.

3. Listed, and a 2024+ model or a Scribe? Then the cable and the Mac are fine. You need an MTP client:

Amazon's USB File Manager in Send to Kindle. It's free and it's Amazon's own app, but it's Intel-only code that needs Rosetta. It only does drag and drop, and Amazon caps a single transfer at 2,000 files.
OpenMTP. It's open source, version 3.3.0 shipped on 2026-08-22, and it has a separate native arm64 build.
calibre, if you already manage books there. Its own MTP driver gained KFX import from "2024 Kindles that use the MTP protocol" in version 7.25.0 (February 2025).

Run only one at a time. The libusb copy inside Amazon's app carries the error "another process has device opened for exclusive access", Amazon's first troubleshooting step is "Close other USB file transfer applications", and the MobileRead thread found calibre couldn't see a Scribe while Android File Transfer held it. Android File Transfer itself is gone: android.com/filetransfer now redirects to a Quick Share page for Windows.

What owners ran into

Pete Graham bought a 12th-gen Paperwhite on Black Friday 2024 and wrote up the result: a chatbot's troubleshooting steps, Amazon's own Send to Kindle app and six Amazon support departments didn't solve it, and OpenMTP did. On Hacker News one commenter summed up the switch as "mildly annoying for Mac users", while another reported Android File Transfer crashing on transfers of hundreds of files and recommended Amazon's MTP app instead.

If you only move a few books, the wireless route skips all of this. Send to Kindle accepts files up to 200 MB each, according to the same Amazon page.

FAQ

Why does my Kindle charge but not show up on my Mac?

Kindles released in 2024 or later, and the Kindle Scribe since firmware 5.16.3, use MTP instead of USB mass storage, and macOS has no MTP driver, so they charge without mounting. Older Kindles that charge but don't appear usually have a charge-only cable, or are waiting for accessory approval on an Apple silicon MacBook.

Does Amazon's USB File Manager work on M4 Macs?

Amazon only lists Intel and M1 to M3 Macs. The app is x86_64-only code, so on any Apple silicon Mac it runs through Rosetta, and an M4 can run Rosetta just like an M3. I couldn't test a transfer without a Kindle. Apple keeps general-purpose Rosetta only through macOS 27.

Is Android File Transfer still available for Kindle on Mac?

No. Google discontinued it, and android.com/filetransfer now redirects to a Quick Share page for Windows. OpenMTP, calibre and Amazon's USB File Manager are the remaining USB options.

How I checked: on 2026-10-05 on a Mac mini M4 (Mac16,10, macOS 26.4.1 build 25E253), I listed /System/Library/Extensions and /System/Library/DriverExtensions, read strings from ptpcamerad, and expanded Amazon's SendToKindleForMac-installer.pkg (44.2 MB, package 1.1.1.260) with pkgutil --expand-full without installing it, then ran lipo, otool and strings on its binaries. The model table comes from Amazon's help page plus the MobileRead thread for the Scribe firmware number; the libmtp count is from the master branch of music-players.h on the same day. I don't own a Kindle, so no transfer was tested on this machine. Every owner experience above is quoted from the linked threads.
