There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
I am having a similar problem. Did a system upgrade yesterday and my photos all went away. I can see my iPhoto file in my User Photos folder, but no photos. Can't import them in either. The selection is grayed out. Tried to rebuild my library as you suggested above. No luck. For a while I was seeing the Events and Photos as black squares (when clicked on I got the !). Now I have nothing. I'm afraid all of my photos are lost. My last Time Machine was in Sept. so I can revert back to that (hopefully), but I'd like to avoid this problem by knowing what happened. Help please... I've tried all of the things seen on the posts (Control/Alt while launching, etc.).
when clicked on I got the !
The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
TD - thanks for the quick response, but I had already tried this and no go. It creates the new Library, but can't see the pics. I can't import from my previous library either. I made an appt. with the genius bar for tomorrow and may have to wait and see if they can figure it out. Hoping for the best. Again, I have time machine backup, but I'll lose my last camera import, which I just did. Any other ideas to try?
Sorry. I put in my first post that I had tried all of the suggestions on the support communities site, but let me be more specific.
- First, I tried the reinstall Library instructions and crossed my fingers. No luck.
- Then I followed some path information about where my library should reside. It looks ok and is my Pictures folder under my User Name.
- I'm still seeing my folders in iPhoto, but nothing in them. Also, I can see my events and photos, but they are just black squares. They still indicate the numbers of photos in them, but when you click on the black boxes, you just see the !.
- I've tried importing from my Photo Library. When I do that, I can import strange collection of random photos and icon jpegs that seem to be web downloands or something. I'm now not convinced that is really my Photo Library, but I've never had any other library. That file shows that I have 240MB of something.
- I had some photos that I had recently emailed to someone so I went into the email and resaved them to iPhoto. They showed up just fine.
At this point, I'm afraid to try anything else and hurt whatever I have. As I said, I'm going to the Apple store tomorrow and may let a genius try and figure it out. I fear user error and that when I did my last system upgrade I somehow trashed something that I wasn't supposed to. I actually worked for Apple for almost 9 years as the head of Education Marketing. I can usually figure stuff out, but this one has me stumped! If you have anything new for me to try, I would certainly give it a try, but if not, I understand and will wait for the genus to look at it. If you'd like, I can report back and tell you if they work some kind of magic and recover my photos.
TD, I said I'd report back after my trip to the genius bar and I'm happy to say there was a positive outcome. It was a long process and many magic keystroke commands to find my original files (something he said he wouldn't recommend a user do on their own), which had moved somewhere mysterious during my system install process. We also had to recreate some of the pics from my last Time Machine backup (thank goodness for TM!). I lost a few pics from my most recent camera export, but I'm relieved to have the last four years back. We then reinstalled the Library Manager and presto, I was good to go.
Thank you for your help. Nice ot know you guys are out there.
