Fix Adobe Acrobat X Pro Crashing on Startup in macOS Mojave
Question details
The user is unable to open Adobe Acrobat X Pro on macOS Mojave because the application crashes immediately upon launch, and the built-in update utility fails to connect to the update server.
- Product
- Adobe Acrobat X Pro 10.1.1
- Device & OS
- macOS Mojave 10.14.6
- Scenario
- Launching the PDF software to view or edit documents on a Mac computer.
- Observed behavior
- The program crashes shortly after starting, and attempts to use the built-in update utility result in a failure to connect to Adobe's update servers.
Ensure that you have administrative privileges on your Mac and save any open work in other applications before resetting preferences or making system-level changes.
Reset Adobe Acrobat Preferences
Resetting the application preferences can resolve corrupted configuration files that frequently cause crashes on startup.
Corrupted preference files are a common cause of unexpected crashes in Adobe products. By removing these files, Acrobat will generate fresh, default configuration files the next time you launch it.
Ensure Adobe Acrobat X Pro is completely closed. If the application is frozen, press Command + Option + Esc, select Acrobat from the list, and click 'Force Quit'.
Open Finder, click on 'Go' in the top Apple menu bar, press and hold the 'Option' key on your keyboard, and select the 'Library' option that appears.
Navigate into the 'Preferences' folder. Locate any files or folders starting with 'com.adobe.Acrobat.Pro' and drag them to the Trash.
Launch Adobe Acrobat X Pro again. The software will take a moment to rebuild its preference files. Check if the startup crash has been resolved.

Frequently Asked Questions
Why does Adobe Acrobat X Pro crash on macOS Mojave?
Acrobat X Pro is an older software version released well before macOS Mojave. Apple introduced significant framework changes in Mojave, resulting in compatibility issues that cause legacy 32-bit or older applications to crash upon startup.
Can I use the built-in utility to update Acrobat X Pro?
No. Because Adobe has ended support for Acrobat X, its dedicated update servers have been taken offline. This is why the built-in update utility fails to connect and cannot patch the software for newer macOS versions.
Where can I find the Adobe Acrobat preference files on a Mac?
Preference files are located in the user's hidden Library folder. You can access it by opening Finder, selecting 'Go' from the menu bar, holding the 'Option' key, clicking 'Library', and then opening the 'Preferences' directory.
Will resetting preferences delete my saved PDF files?
No, resetting the application preferences only clears software configurations like toolbar layouts, recent file lists, and default settings. Your actual PDF documents are stored separately and will remain completely unaffected.
