On my MBP, I have images that have the yellow triangle indicating the originals are offline. I couldn't find the originals, but when I look at Aperture on my iMac they are there. I tried to merge the library from my iMac on my MBP. The size more than doubled, but I am still struggling with offline images. How can I best solve this problem? I purchased the PhotoSweeper app, but my first time running it I didn't really see the desired results and didn't want to delete the photos. Any help is appreciated.
