Highlight copy and paste MacBook Pro quit working

For whatever reason I have been unable to highlight copy and paste on the MacBook Pro, using the trackpad. This just started, is there a problem with the most current version of iOS? Finding nothing current on this problem, or solutions. Anyone have this and know of a solution?

macOS...(?)


Have you shut down and restarted to compare your results...

>Shut Down


verify your software is up to date—The current stable release of Tahoe including bug fixes, security updates is macOS 26.2

Keep your Mac up to date - Apple Support

Keep your Mac up to date - Apple Support


—is there a third party mouse involved here?


—are you using a third party Firewall?


—Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS


—Verify Full keyboard access did not get turned on...

>System Settings>Accessibility >Keyboard>Full Keyboard Access>OFF



To trouble shoot further you can:


—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test. Caches get rebuilt automatically.


This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.

 


—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account.
