BT mouse does not connect

[zalle]

Hello guys,

2015 27" iMac, bluetooth mouse is a newer version (M1 macs I guess, it's pink underneath with internal battery). Whenever I turn my mac off, it does not reconnect. I need to use a wired mouse, to reconnect it.
It shows up in the BT settings, I just need to press "connect".

Why could this be happening?

Thanks

Older version of macOS, possibly? With an internal-battery Magic Mouse, you can plug a Lightning cable from the computer to the mouse, which will cause it to pair.

That sounds like a good idea. Thanks
