Preview sometimes does not save changes

I have a 2021 MacBook Pro 16" with M1 chip.

Lately, when attempting to save a pdf with text I have added it sometimes fails to save the file with the changes. I have been calling Apple about this, but it continues to happen occasionally. They have no solution, I suppose because it does not happen every time.

MacBook Pro 15″, macOS 10.14

  1. It is a pdf attachment downloaded from an email. It is on my desktop.
  2. No error message. It just drops various amounts of the changes just made to the document.
  3. Only text. Rather than clicking on "Annotate: text" each time, I copy the last text block and paste it, and then edit that text.
  4. The agent screen sharing with me did not say I should not do it that way.
  5. I have tried duplicating and then saving, just saving, or just quitting the app. No matter the case, sometimes changes are not saved.
  6. Yes, the OS is version 12.6.

Thanks for your help.

chenderson22, 


Please tell us more. Some things to note, to better isolate the situation are: 

• Where do the files this happens on originate from? 

• What is the error message when this happens? 

• What type of changes are you making that don’t save? 

• Do these files save to an external drive, iCloud, your local drive or somewhere else? 


You mentioned that the issue happens occasionally, which makes some normal isolating steps hard to take such as testing in a new user. That’s why we want to try and pinpoint answers to the questions above.


Another step you can verify, that can be verified regardless are - 

Is your macOS up to date? That’s visible in Apple menu > About This Mac. 


Thanks.
