Use iBooks to proof your ePub books

The new book proofing feature in iBooks for OS X Yosemite lets you see and interact with your ePub books on Mac and iOS devices just like your readers will. Use this feature to preview rich graphics and test interactive content in your book before you submit it for sale on the iBooks Store.

Get your ePub ready to add as a proof

Before you can create an ePub proof, make sure your ePub is in the right format (a folder, not a flat file). To check this, right-click your ePub and see if Show Package Contents appears in the menu. If so, you're ready to create your ePub proof. If not, follow these steps:

  1. Create a new folder on your Desktop or in Finder.
  2. Launch Terminal. You can search for it in Spotlight, or go to Applications > Utilites in Finder.
  3. In the Terminal window, type cd followed by a space.
  4. Drag the folder you created into the Terminal window and press Return.
  5. Type unzip followed by a space.
  6. Drag your ePub file into the Terminal window and press Return. 
  7. Right-click the folder you created and choose Get Info.
  8. Under Name & Extensions, add .epub to the end of the folder name. 

Create an ePub proof and add it to your iBooks library

To create an ePub proof, you need to use the Advanced menu in iBooks for OS X Yosemite. If you don't see the Advanced menu, follow these steps:

  1. Go to the iBooks menu and choose Preferences.
  2. Click Advanced and select “Enable Advanced menu in menu bar."

When you see the Advanced menu, follow these steps: 

  1. Go to the Advanced menu and choose “Add ePub to Library as Proof…”
  2. Select your ePub file in the dialog that appears. 
  3. Click Add, then look for your ePub proof in your iBooks library.

Sync your ePub proof with your iOS devices

After you create an ePub proof, you can sync it with your iPhone, iPad, and iPod touch. This way, you can see and interact with your book on different devices. To sync your ePub proof, you need iBooks on a device with iOS 8 or later.

  1. Connect your device to your Mac.
  2. Open the iBooks app on your device.
  3. Open your ePub proof in iBooks on your Mac.
  4. Click Devices in the ePub on your Mac and select each device that you want to sync.

After you sync your ePub proof, any changes you make to it on your Mac will update automatically on all iOS devices you've synced.
