Question :

I am trying to open a JPG-picture in Preview.app, but I get this error : “the file couldn’t be opened because you don’t have permission to view it“

What can I do ?

Answer :

It isn’t clear why you get this error message, but the way to fix it is rather simple :

• first, Quit the Preview.app if it is open :
  • press the [CMD]+[Q] key-combo on your keyboard
• then reopen the Preview.app
• then Force Quit the Preview.app :
  • press the [CMD]+[ALT]+[ESC] key-combo on your keyboard
  • when the new window opens, select Preview (the app) from the scroll-list
  • then click on the Force Quit button (bottom-right)
• then reopen the Preview.app
• now, the JPG files should open in Preview.app without a problem

That’s it !

enjoy 😉
