Follow the on-screen prompts to download and install any available updates, ensuring you are on version 20.009.20065 or newer.
Once the update is complete, fully quit Adobe Acrobat and restart your macOS device to apply the changes.

Frequently Asked Questions
Why is my PDF lagging so much when scrolling or switching on a Mac?
This typically occurs due to high-resolution graphics, complex vector elements within the PDF, outdated software versions, or rendering engine conflicts with macOS graphics drivers.
Can disabling 2D graphics acceleration fix the screen refresh issue?
Yes. Sometimes the application's hardware acceleration conflicts with the Mac's graphics drivers. Toggling 'Use 2D graphics acceleration' in Acrobat's Page Display preferences forces the software to render differently, which often resolves display delays.
What should I do if updating Acrobat doesn't fix the slow refresh?
If updating does not resolve the issue, try testing a completely different, text-only PDF to rule out file corruption. If the problem persists across all files, consider reinstalling the application or using a lightweight alternative like WPS PDF for faster performance.
