I am trying to download iBooks Author for an older Mac, but I am a little worried out using this website. I am using my school computer and need to return it without any viruses on my computer. Thanks.
No, there is no malware on this website. Also, the iBooks Author is a shareware application available through the Windows Store.
Visit the following page and then click on the green Download button: http://ibooks-author-101-ib-for-windows-8.software.informer.com/
It will take you to the Windows Store from where you can purchase it.
