Update Adobe Acrobat X to Version 10.1.16
Installing the final official patch can resolve lingering stability issues and compatibility bugs on older operating systems.
Adobe Acrobat X is an obsolete product. However, updating to its final release version (10.1.16) is necessary to patch critical bugs that cause immediate crashes on startup.
Try to open Adobe Acrobat Pro X. If it stays open for a few seconds, immediately navigate to 'Help' in the top menu bar.
Select 'Check for Updates' from the dropdown menu and follow the prompts to download and install version 10.1.16.
If the app crashes too fast to use the built-in updater, download the 10.1.16 patch directly from an official Adobe legacy software archive, run the installer package, and restart your Mac.

Adjust System Date to Bypass the 2020 Bug
A known validation bug causes older Acrobat X versions to crash if the system date is set past 2019.

Frequently Asked Questions
Why does Adobe Acrobat Pro X keep crashing on my newer macOS?
Adobe Acrobat X is an obsolete program that was officially discontinued. It lacks updates for modern macOS architectures and encounters fatal errors, such as the known validation bug triggered by system dates advancing past 2019.
Where can I safely download the Acrobat X 10.1.16 patch?
Because Acrobat X is no longer supported, Adobe has removed most official direct download links. You may need to locate it through enterprise deployment archives or Adobe's legacy FTP servers, but upgrading to modern, supported PDF software is strongly recommended for security.
Is rolling back my system date a permanent fix for Acrobat X?
No. Reverting your system date to 2019 is strictly a temporary workaround. Leaving your computer's date incorrect will eventually block access to secure websites and disrupt basic application syncing.
Can I edit my existing PDFs smoothly without using Adobe Acrobat?
Yes, modern productivity suites like WPS Office feature built-in, lightweight PDF editors that are fully compatible with current operating systems, avoiding the legacy crash issues completely.
