Photos export error
I recently upgraded to Yosemite Version 10.10.4 on my Macbook Pro (13-inch, Late 2011) with a 2.4 GHz Intel Core i5 processor and a 4 GB 1333 MHz DDR3 memory. Now Photos doesn't work when I try to export to a folder. When I click on export photo, I get an error message that says "Export Complete with Errors." "0 (of 1) files have been exported to: blog. The export operation failed to create a file for the photo identified below." Then it says the file name and the error message "Could not load image (1,019)."
I don't know what the 1,019 refers to.
When I click on "Export Unmodified original" I get a similar error. It says
Export complete with Errors
0 (of 1) files have been exported to:
blog
The export operation failed to create a file for the photo identified below:
Then it has the filename and the following error message
The file "IMG_2578.JPG" couldn't be opened because there is no such file.
I don't get the above error message because there is clearly such a file.
Any help? Thanks!
