Download kindle bools to my MacBook Pro laptop?

Jill - There are a lot of apple operating system drivers for your printer. You need to match the operating system your macbook has and download the driver file from the macbook internet browser and install it on your Macbook Pro. (don't download it from a non apple p.c as apple won't read the file without hassle )

Close the Kindle app and restart it. If that does not help, try restarting your MacBook.
If that does not work, try deleting the Kindle and reloading it on your system.
Everything you got from Amazon will still be in your Amazon account.

When you register the Kindle on you Macbook, all your books will appear in your library.
