Sure, thanks -- everything's new and latest, but here are the details:
Yesterday, I got a new MacBook Pro, running OS 10.8.4 and iPhoto '11 (version 9.4.3).
My old computer is running OS 10.6.8. I'm not certain which version of iPhoto it was running, because when some computer techs replaced my hard drive recently, they didn't take steps to keep the applications, and didn't reset the admin password. Since my CD/DVD drive is busted, I couldn't create a new admin password, which meant I couldn't reinstall iPhoto from the old disk and get updates. It may have been iPhoto '08, version 6.06, but I'm not able to figure that out, and I'm hoping that's irrelevant. Buying a new computer to replace the dodgy ancient one was meant to get me out of this kind of jail.
My objective here was simply to import the old computer's iPhoto Library onto the new computer.
When I first plugged my new MacBook Pro into my old MacBook, yesterday, I connected the computers via Ethernet cable, and opened File Sharing on the old one. First I transferred assorted document folders, then music for iTunes. These transfers seemed to be fine. (The iTunes playlists are similarly absent, mind you, but I haven't even looked at that issue yet.)
I then clicked and dragged the old iPhoto Library and dragged it to the new system. It transferred roughly 18 GB of files, including about 14,000 images. All these images are opening just fine, so they're not just thumbnails.
However, it's not showing me any albums, and the old computer's iPhoto had numerous albums. When I look in Finder, there's a folder called "Albums" (with names like "%1dtN5blQQiF27mQgrTbDQ.apalbum") inside the folder "Database", but clicking one of those gets me "There is no application set to open the document '%1dtN5blQQiF27mQgrTbDQ.apalbum'."
The only error message was that the systems said that either some of the files I was trying to transfer were locked, or I didn't have permission to read them. As I said, though, I couldn't figure out how to confirm which files those were.
- History of the problem: no history, as I've had the new computer for less than 24 hours. (Personal history: I've used only Macs for my whole adult life, being an owner since 1992, so I can guarantee I'm not accidentally using any PC-type thinking on the problem.)
- Attempted fixes: I repeated your steps twice, with the same outcome each time. I then tried copying and pasting the Library, rather than dragging it, but it had the same outcome. I then tried replacing just the file AlbumData.xml, which had no effect.
