Facing this issue while working on appium. couldnt able to launch the app in the simulator as appium server is throwing the above error. In my case I had installed appium from a different user and the owner of the Appium.app was other user than the user I was trying to run from. Changing the owner to the current user resolved the issue. I resolved this error by running ps aux | grep appium from command line, kill all appium and node processes and then restart appium. 来源： https://stackoverflow.com/questions/22248328/a-new-session-could-not-be-created-original-error-instruments-crashed-on-star
