    This problem started after updating to 11.6.6.
    When I opt to download a PDF of my statements, I get a notice that the file could not be opened because I don’t have permission to view it. The file is shown on the screen and it can be downloaded, but it will not be opened as a PDF. Once it is downloaded I have no problem opening it in Preview.

  2. this was very helpful… i could not open any of my files… i opened Preview and then opened a file from within the app and everything seemed fine… i’ve never had this issue before and hopefully it doesn’t come back… now i can open all my files from the finder… 🙂

  3. I found this post via a search as I was having this same problem but it was only those files on my desktop. All file types, pdf, numbers, pages, png and jpg to name a few. Files in other folders were opening fine.

    I made it to Step 2 above (the restart) and it started working again.

    Thanks for the tip!

  4. I have a similar problem with Xcode. Xcode crashes the system several times every day. After some crashes Xcode refuses to open any Xcode project file in the file system or at icloud. There are several ways to fix this problem.The most consistent fix is to reboot the the system at least once more after the automatic reboot following the cash. Possibly the automatic restart may be causing the problem. So far, I had about 20 to 40 system crashes while using Xcode. Most caused Xcode to refuse to open project files. I have reported the bug to Apple about two weeks ago.
