My OneNote program keeps shutting down with this error message

The first thing I would recommend attempting is a file system check and permissions repair:

- Reboot the computer in recovery mode

- Start the disk utility

- Select the disk

- On the first aid tab, select repair disk (wait for a long time)

- On the first aid tab, select repair disk permissions

The second thing I would recommend is to manually change the permissions of of your home directory via the terminal:

- Open a terminal and enter the following commands:

whoami

(this returns your username, likely your first and last name without spaces)

cd ~/..

(this changes to one folder above your home folder)

sudo chown -R [username] [username]/

(enter your password when prompted and be sure that you replace [username] with your username, this will ensure you have ownership permissions to everything in your home directory)
