Adobe Pro DC version 2021.001.20155 Crashing in MacOS Big Sur version 11.3.1

[andrewb53151810]

I am running Adobe Acrobat Pro DC version 2021.001.20155 on an iMac running MacOS Big Sur version 11.3.1 w/32 GB memory.  The Acrobat program is crashing almost every time I try to edit or notate a large pdf document (37.1 MB) or two Adobe pdf documents (9.1 MB + 37.1 MB).  It almost always occurs when I increase the magnification level to say, 100% or 200%.   For reference, memory used is 21.85GB of 32 GB when both docs are open.   Please advise if this an Adobe issue or Apple issue. If it is an Adobe issue, please advise what I can do to prevent these crashes. . . . Thanks, Andrew Bermant

Hi Andrew

Hope you are doing well and sorry for the trouble. As described the application is crashing when you try to edit or annotate a large PDF file.

- What happens when you try to edit a small PDF file? Is the the application crashing now as well? Please try with a different set of PDF files  and check the behavior of the application.

- Is the PDF file is stored on a shared network/drive? If yes, please download it to your computer locally and then try to edit and check if that helps.

- What is the version of the Adobe Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version installed. Go to Help > Check for Updates and reboot the computer once.

If it still doesn't work, please try to reset the Acrobat preferences to default as described in the help page - https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792...

You may also try to create a new test user profile with full admin rights or enable the root account in Mac and try using the application there
