If your Bluetooth mouse or keyboard does not reconnect after a reboot at the login screen and only reconnects after the login, this might be related to FileVault encryption.

When FileVault is enabled, Bluetooth mice and keyboards will only re-connect after login.

Potential solutions:

• Upgrade your MacOS to the latest version
• If your Logitech device came with a USB receiver, using it will solve the issue.
• Use your MacBook keyboard and trackpad to login.
• Use a USB keyboard or mouse to login.
