First time poster here... has anyone else had problems with LR crashing their IMac? I am working on a 8 month old IMac and it crashes when I'm using LR heavily. I updated LR a few days ago and the problem seems worse. Just now I was in LR editing and it crashed 5 times within an hour!! You can imagine how frustrating this is. I am using no other program when it does this. Today it repeatedly happened when I was using the spot healing tool. Any help is appreciated!
