Can't open my 118g Photo library
Last week, Photo forced me to update my library which is 118gigs. I did so but had a spinning wheel for 5 days. No progress bar showed. I finally had to force quit it. Then I thought to rebuild the library and I held option-command while opening Photos. But the repair window didn't appear.
I can't open my photo library and I'm getting frustrated. Any advice would be welcome.
