10.10.3 is full of bugs and the worst of this version is Photos that by no way is better than iPhoto. Why Apple could think that Photos is better than iPhoto, it has crashed a lot of times and when I try to import photos of my iphone I can't, also it is too slow. When you have thousands of photos everything is too slow. I have already need to restart 10.10.3 because it show me all type of errors and closing all apps. Apple needs to keep building iphoto because it is a lot better than photos.
