apple mouse not connecting during os installation
Reinstalling macOSX 10.13.6 on iMac mid 2010. Created bootable USB but during installation, I get a spinning wheel while the mouse is attempting to connect. The batteries are good, I get a blinking green light on the mouse, but the bluetooth will not connect, system is stalled.
Cannot seem to move past this phase, not sure what to do next.
iMac 21.5", macOS 10.13
