Not able to close application.

Hi Junes,

Adobe is the name of the company. Which Adobe application you are referring here? I assume that you are taking about either Adobe Acrobat or Reader DC?

Do the following to rectify this problem-

• First Reboot your computer (after saving all the ongoing work opened, so that you wont lose them).
• Open app and see if it freezes on closing. If yes, then Open Activity monitor an quit Acrobat processes.
• Reopen App, check whether it has got the latest patch installed or not. open Acrobat>Help>Check for update.
• Related help doc: Troubleshoot Mac OS 10.x system errors, freezes | Adobe software

Let us know how it goes.

Thanks,
