I exported my iBook and got the .ibooks file on my Desktop(iMac Retina 5K), I tried to put the file into the iBooks application but I get a message that says "The file "______.ibooks" couldn't opened because it isn't in the correct format.
I exported my iBook and got the .ibooks file on my Desktop(iMac Retina 5K), I tried to put the file into the iBooks application but I get a message that says "The file "______.ibooks" couldn't opened because it isn't in the correct format. I took the same file and transferred it in my MacBook Air and was able to put it in the iBooks application no problem, the MacBook Air runs OS X v 10.9.5
Please advise as to Why it would work on an older OS X version as oppose to the newer OS X Yosemite
Thanks
