So, I have a 2011 13" MacBook Pro with 8GB of RAM and Mac OS X 10.7.3. I'm still running iPhoto '09 version 8.1.2. I guess I've reached iPhoto's limit with 190,000 pictures. iPhoto has ground to a halt. I've never deleted a picture that I've downloaded from my camera, until now I never thought I would need to. But it's so slow now I can't do my regular routine of editing pictures from an event down to an album that I use iWeb to publish (now) to my own site. I've take a look at the Activity Monitor and iPhoto not overloading the CPU, paging out because it's ran out of RAM nor is it taxing the hard drive. So, I guess I need to edit out some of the older pictures that I've never put into an album.
I already had a smart album callled "Everything Editied" which includes every picture that's ever been added to "any" album. I thought I'd be able to do the opposite and create a smart album with every picture that's NOT in an alubm. I can do that, but I can't delete any pictures out of it. I'd really like to keep all of the pictures I've taken the time to edit for use, I don't want to just delete old events. (I've been taking more and more pictures over time, so even if I delted all the pictures from 2004-2008 It wouldn't clean-out all that many. Also, I've spent a whole lot of time geo-tagging my pictures and removing edited pictures just because they're old will remove them from the map.
Any suggestions for removing un-edtied pictures from older events? I've put captions on most, but not all, of the edited pictures, so deleting generic-named pictures isn't an answer...
