Hello, wondered if anyone had played with iBooks on Yosemite and had same issues as I. So, backed up ibooks directory in Mavericks. Put it into place on Yosemite, started up iBooks - and nothing. This always works on Mavericks, so I think they changed a code or maybe even that iBooks is an updated version - the reason I say this, and it's good news, is that on Mavericks you can't edit any metadata, but, on Yosemite, under list view, you can edit and change the category, author and collection sections. You can't batch edit sadly, but you can indeed edit them one by one or by using tab. It's good news for those using iBooks to sync non iTunes pubs I think! Chris.
