First check the Adobe ID of Digitial Edition on your Macbook.
- Start Digital Edition.
- Go to Help > Authorization Info.

- Check which Adobe ID you was display.

- CHeck if you can open the eBook on this device.

Then check if you used the same ID on your iPad. If yes try to authiorze new after remove.
