Where can I download iBooks for Mac？ I did not find it in APP store. Thanks
See the quote below from https://www.apple.com/support/mac-apps/ibooks/
iBooks is included with OS X v10.9 or higher. Visit OS X Support to learn how to get the latest Mac OS X software.
My Mac is OS X 10.10.
Then you should already have iBooks. Have you tried Spotlight Search (command spacebar or magnifying glass icon near right of menu bar) and search for iBooks?
In fact，I had it before. But I deleted it some day. The problem is that I don't know how to install it again. Thanks
Do you have a backup. If so you should be able to restore it from that. Otherwise you can reinstall OS X. See Carolyn's post in I accidentally deleted iBooks on my Macbook Pro (late 2011) running on OS X 10.10.1 Yosemite. Will iBooks be reinstalled if I install the next OS X major update once it is out?
