If you're trying to put a PDF on the Kindle app on your tablet, use the email method instead. Since Mac computers can't access Android file systems on their own, you'll need to install Android File Transfer to bridge the gap:  Go to https://www.android.com/filetransfer/ in your Mac's web browser. Click DOWNLOAD NOW. Double-click the downloaded DMG file. Click and drag the Android File Transfer icon onto the "Applications" folder icon. Go to the location of the PDF you want to add to your Kindle, then click the PDF and press either Ctrl+C (Windows) or ⌘ Command+C (Mac). Plug the USB end of your Kindle's charger cable into one of your computer's USB ports, then plug the other end of the cable into your Kindle's charging port. This step will vary depending on your computer's operating system:   Windows — Open File Explorer (or press ⊞ Win+E), then click your Kindle's name in the left-hand sidebar. You may first have to scroll down on the sidebar to see the Kindle here.  Mac — Android File Transfer should open immediately. If it doesn't, open it by typing android file transfer into Spotlight and then double-clicking Android File Transfer. If the Kindle doesn't open to a list of folders immediately, double-click the "Internal" or "Internal Storage" folder to open it. Skip this step on a Mac. This is the folder in which your Kindle's files, such as PDFs and Word documents, can be stored. Double-click it to open it. If you're uploading the PDF to a classic Kindle, this folder may be entitled "Documents" instead. Once the "Docs" folder opens, press Ctrl+V (Windows) or ⌘ Command+V (Mac) to paste the copied PDF into the folder. This will place the PDF on your Kindle. and remove your Kindle from the computer. After safely ejecting your Kindle, you can detach it from its cable. Unlock your Kindle, then open the "Library" section of the Kindle to view the PDF. Once the PDF appears here, you can select it to open it.
