I was importing pictures from my iphone to my macbook. In the middle of importing process, my iphone got disconnected and my iphoto started to have problems. I could not even switch off my macbook cause it says that photos are being imported although i have disconnected my iphone from macbook. I tried to leave my macbook for several minutes until the batterry ran out but once i turned it on again, it remained the same. Now i cannot do anything, both closing my macbook and transfering any photos from my iphone to macbook. Maybe any solutions for this? Thanks so much!
