iMac not working with trackpad

Hi,

To fix an Apple Magic Trackpad that moves the pointer but won't click after upgrading to macOS Sequoia, reset your Bluetooth connection and trackpad settings.

Quick Fixes

• Restart your Mac: Turn your iMac completely off and back on to clear temporary system and driver glitches.
• Toggle Bluetooth: Click the Apple Menu > System Settings > Bluetooth, turn Bluetooth off for 60 seconds, and turn it back on to refresh the bluetoothd background process.
• Check "Tap to Click": Go to System Settings > Trackpad, and make sure Tap to click is turned on so a light tap registers as a click.
• Adjust Click Pressure: Under System Settings > Trackpad, check if Force Click and haptic feedback is enabled, and try changing the click pressure slider.
• Check Accessibility settings: Go to System Settings > Accessibility > Pointer Control, and ensure that an option like "Ignore integrated trackpad when a wireless mouse or trackpad is present" isn't misbehaving or conflicting with your setup
