cannot open file for lack of authorization - which I have

Hey there nikolaus21,

Thanks for visiting the Apple Support Communities to get help with your Mac. From what you've described, it sounds like you are receiving a permissions error when attempting to open documents. If that's the case, the information in If you don’t have permission to use files on a Mac disk - Apple Support, which discusses granting permissions, may help.

If you have gone through the steps there and still need help, don't hesitate to respond back. If you do respond, please let us know the following details, which can help us get on the right path forward:

• Does this happen with all files, or just certain files?
• Does this happen with all apps, or just certain apps?
• What is the exact message you receive?

Best!
