Iphoto freezes when I try to look at any pictures
Just purchased a new macbook air and migrated all my data including pictures. When I try to open iPhoto, many images are missing (marked with exclamation point) though thumbnails can be seen.
I have rebuild the database, reinstalled iPhoto, rebooted, deleted the iphoto library and re-imported from back-ups but nothing works. Now the new version of iphoto (with no photos imported) and only images in it being from my current icloud photo stream, just freezes if I even attempt to look at a picture.
Please help...need to clear off old computer but afraid to do so until I have all my pics available on the new one. Thank you!
