Thank you for your help. I've attached the log.
I don't think your computer meets all the requirements. Specifically, the graphics card is too old. X-Plane 11 requires a NVIDIA GeForce 420 or newer, and the log shows a NVIDIA GeForce 320M. The log also shows it is installed in the Applications folder, which doesn't work for X-Plane and can cause permissions issues. We strongly recommend installing to the desktop.
You may be able to run X-Plane 10 on your laptop if you'd like to get that demo here.
