Preview shows blank screen for PDF docs
Preview is showing a blacked out screen where the document should be.
* MacBook Air (11-inch, Mid 2011)
* upgraded to 10.13.1 within the past week
- behavior did not exist before "upgrade"
- issue limited to PDF's generated by Preview via scan operations
- fwiw the scan ops are via wireless network but i don't think that's the problem
- in Preview "view Thumbnails" and "view Contact Sheet" render thumbs properly
- as file opens you can see the doc image briefly and then it is blacked out once loaded
- files with above behavior open successfully in other apps ( i.e. browser, Adobe Reader )
- files print successfully
- behavior does not occur if I scan in preview and save to jpeg, png or tiff
- older files generated via Preview scans on older versions of OS affected
* this behavior apparently was a known bug in Lion if I remember right
* some folks found relief by deleting .com.apple.Preview.plist ; i did not😟
* no updates show up as available in app store
any ideas?
