Launch the downloaded utility and follow the on-screen prompts to completely uninstall Acrobat and wipe its remaining preference files.

Frequently Asked Questions
Why won't Adobe Acrobat close on my Mac even when I try to force quit?
Acrobat relies on multiple background processes, such as Adobe IPC Broker or CoreSync. If one of these background tasks hangs, the main application cannot close properly. You can resolve this by opening the macOS Activity Monitor, searching for 'Adobe', and forcing all related processes to quit.
Will using the Acrobat Cleaner Tool delete my saved PDF files?
No, the Adobe Acrobat Cleaner Tool is specifically designed to only target and remove application files, temporary caches, and corrupted preference folders. Your personal PDF documents stored on your hard drive or cloud storage remain completely untouched.
Can I open my PDF files on Mac without using Adobe Acrobat?
Yes, macOS includes a built-in application called Preview that can view standard PDFs. Additionally, you can use highly compatible third-party software like WPS Office, which provides advanced PDF editing and reading capabilities without the heavy resource usage.
