Lightroom lost edits transferring to new computer
I recently bought a new Mac. I used my Apple Time-Machine to transfer my files from my old computer. I opened Lightroom and opened my catalog. My photos through fine, but I have files where the edits did not come with the photo. The preview shows the edited image until I click to open it. Then the edits disappear, and the preview shows the original, unedited image. (Though the preview continues to display the 'stars' or color filters.)
Any suggestions where to go to find the edits? Perhaps in an earlier catalog?
