Magic mouse disconnects when left idle
This has been occurring since I installed Security Update 2018-002 for High Sierra. If I leave the mouse just sitting, it will disconnect after 15 seconds or so. Double clicked will reconnect it. As long as I am moving it around regularly, it works fine.
I have tried removing it from the Bluetooth control panel and re-adding it, both with and without rebooting in-between, and resetting the Bluetooth module. Nothing has changed.
