You do not have permission.

Question

"The document xxxx could not be saved. You do not have permission."
Why do I suddenly get this message?  I'm the only one that uses this Mac.  Permissions says I have read/write permission.  What is going on?

Startup holding command-r keys.
You will boot into the Repair Utilities screen. On top, in the Menu Bar click the Utilities item then select Terminal.
In the Terminal window, type resetpassword and hit Return.
The Password reset utility launches, but you’re not going to reset the password. Instead, click on the icon for your Mac’s hard drive at the top. From the drop-down below it, select the user account where you are having issues.
At the bottom of the window, you’ll see an area labeled ‘Reset Home Directory Permissions and ACLs’. Click the Reset button there.
The reset process takes a couple of minutes. When it’s done, quit the programs you’ve opened and restart your Mac. Notice that ‘Spotlight’ starts re-indexing immediately.
