    Hi, i am posting this here to see if anyone else has had this issue.

    I've got both the Magic Mouse 2 and the Magic Keyboard connected via Bluetooth to my iMac (Retina 5K for reference) it's been working flawless since day 1, today i turned on the iMac, get to the login screen but can't move the cursor, caps lock light on the keyboard also isn't working.

    To cut the story a bit shorter it seems that bluetooth has either stopped working or has been disabled/broken somehow, Bluetooth isn't shown within System Preferences now, just gone - also if i try to open it, it says "You can't open the Bluetooth preferences pane because it's not available", also within System Information the Bluetooth section just says "No information found".

    I'm currently working with the Magic Keyboard plugged in via USB and an older mouse that has it's own USB bluetooth transmitter.

    I've tried a basic restart, shutdown and restart, shutdown and remove all USB and power, leaving it for a few mins then plugging power back in etc.

    Anything else i can do, would fresh installation help? could it just be that something can become corrupt, it's a new iMac (within a month or two) so it's not that it's broke due to age, although things can happen at anytime so i'm not counting that out.

    I have the same issue with my Retina 5K.

    When I boot the machine from a turned off state bluetooth is not available, I get it working by a simple reboot.

    Software issue or hardware issue?

    Occasionally, I have the same thing on my late 2015 iMac. No BT after wake, so have to power down or plug in USB cable!

    Yesterday evening I resetted the NVRAM of my Mac and it seems to have fixed the problem. I turned my iMac off and turned it on, the keyboard was responding direct. I hope it stays this way.

    Same here! There I was thinking it was only my issue. What sometimes works is connecting the USB mouse, going to Bluetooth icon and clicking Mouse > Connect. Otherwise reboot.

    OP, I hope the NVRAM reset will fix it for you!

    Thanks for the feedback and good to know i'm not the only one (not good the issue happens) i've done a NVRAM reset and it seems Bluetooth is back now so good to keep that in mind for the future.
