Input Failure on Mac Mini M1 after macOS Tahoe 26.2 Update: Mouse Left-Click and Keyboard Not Responding

When you install mouse driver software, it can interfere with all input devices, not just the mouse it was designed to support. You have to use their uninstaller to remove it.

There are many reports of Logitech drivers not being compatible with Tahoe. I don’t know if they have updated them, yet. It was over twenty years ago, but my experience with Logitech was they were extremely slow to fix their software after an upgrade. The basic functions of the mouse should still work without the drivers.

Since this happens across multiple devices (both third-party and native Apple products), it suggests the issue is with the Mac's logic board, USB/Bluetooth ports, or a system-level software glitch rather than the peripherals themselves.

Restart the computer in Safe Mode 

Do the issues persist ?

If not - there could be something in the main User Account playing up.

To further isolate this - Set up users, guests, and groups on Mac.

Then log out of the Main User account and log into the dummy account and test again if the issue persists.

If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.
