Since I updated to High Sierra the Preview app no longer remembers the sizes and positions of its open windows. Instead it just opens all windows on the same desktop with standardised size and position when the computer starts up.

How do I fix this?

(Side note: After updating the Preview app also didn't remember the last viewed page of PDF-files, but I was able to fix this by deleting the ~/Library/Containers/com.apple.Preview folder. However, the window size and position issue persists.)


Preview does remember the position of windows containing images (JPG, PNG, etc) but for some reason does not restore the position of PDF windows. I suspect this is a bug that will be fixed in a future version of macOS High Sierra.

The saved state for Preview is located at: ~/Library/Containers/com.apple.Preview/Data/Library/Saved Application State/com.apple.Preview.savedState

Meanwhile, you can use an app like Stay to remember and automatically reset the position of any window. It’s a bit heavy handed for this use case but it would let you carry on until the bug is fixed.

You might also look at window managers such as Magnet that allow easy manipulation of windows.

  • Well it happens for me (image windows remembered, PDF windows not remembered) – Matt Sephton Mar 15 '18 at 10:06
  • I had noticed this issue, but it didn’t bother me. I appreciate you must have a workflow where it is bothersome. – Matt Sephton Mar 15 '18 at 14:45

    Yes, image windows do seem to maintain their position. I just checked with a .png file. – Vincent Pfenninger Mar 15 '18 at 17:08

    I have sent feedback to Apple about this bug. I hope they will fix it in a future update. – Vincent Pfenninger Mar 16 '18 at 6:28
