How to Fix Slow Sticky Notes in Acrobat on macOS
Question details
The user experiences severe lag and slow response times when using sticky notes and commenting tools in a PDF viewer on older macOS devices.
- Product
- Adobe Acrobat
- Device & OS
- macOS
- Scenario
- Attempting to add, move, or edit sticky notes and comments on locally stored PDF files.
- Observed behavior
- Commenting tools and sticky notes respond very slowly and lag visually, even on Macs with upgraded hardware running macOS High Sierra.
Ensure your Mac has at least 15% of free disk space and close other resource-heavy applications before troubleshooting Acrobat. Having a backup copy of your PDF file is also recommended before modifying any application settings.
Update Acrobat and Adjust Performance Settings
Updating the software and disabling conflicting features like hardware acceleration can resolve visual lag.
Software updates often contain bug fixes for specific operating system environments. If updating does not work, disabling 2D graphics acceleration can force the application to use basic rendering, which is sometimes more stable on older macOS versions.
Open Adobe Acrobat, navigate to the 'Help' menu at the top, and select 'Check for Updates'. Install the latest version supported by your specific macOS.
Save a small PDF directly to your Mac's desktop. Restart Acrobat, open this local file, and test the sticky notes to rule out network or file-size issues.
Go to Acrobat Preferences (Acrobat > Preferences). Under 'General' or 'Page Display', uncheck 'Use 2D graphics acceleration' if the option is available, then click OK.
Navigate to the Acrobat Preferences or the 'Manage Add-ons' section to disable unnecessary third-party plug-ins that might be consuming excessive memory.
Upgrade macOS or Use a Compatible Acrobat Version
macOS High Sierra is an older operating system that may struggle to run the latest, resource-heavy Acrobat updates smoothly.

Frequently Asked Questions
Why is my PDF viewer suddenly so slow on macOS High Sierra?
Heavy PDF editors require significant system resources. On older operating systems like High Sierra, system architecture and graphics processing limitations can struggle to handle modern software rendering and background tasks, resulting in input lag.
Will adding more RAM to my Mac stop sticky notes from lagging?
While more RAM can help with general multitasking and large files, specific tool lag is often tied to software compatibility, lack of properly supported hardware acceleration, or unoptimized PDF files rather than just physical memory limits.
Is there a way to reduce the file size of the PDF to improve commenting speed?
Yes. You can go to File > Save as Other > Reduced Size PDF in Acrobat, or use the compress feature in WPS PDF. Smaller files load faster, consume less memory, and generally improve the responsiveness of all commenting tools.
How do I safely disable third-party plug-ins in Acrobat on Mac?
You can temporarily move third-party plug-in files out of the Acrobat Plug-ins folder (located by right-clicking the application and selecting 'Show Package Contents') to rule out conflicts causing the lag.
