Hey everyone, I am using a MacBook Pro (Mid 2012) with High Sierra and I am experiencing heavy bluetooth issues with my Magic Mouse 1 since a few weeks. I tried almost everything form: - different mousepads/batteries - PRAM/SMC reset - reset BT module/remove all BT devices/delete BT Pan from network settings/delete BT preferences - disable Handoff - reinstall High Sierra - replaced the BT drivers with those from Mavericks - turned off all BT devices in my apartment - switched to Apple Magic Keyboard from noname BT keyboard - replaced the router with a newer one to use the 5g band Nothing, seriously nothing helped for long. Now, it seems that I figured whats going on. It is so easy, that I am almost too embarrassed to tell. I have been using a Macbook stand now for a while. Something similar to this: Raising up the MacBook a few inches causes issues that serious that I was almost unable to use the mouse. To verify the 'solution' I obviously tried that a few times. It really seems that the stand is the cause of the problem. Any idea how the hell this can happen? I mean that's just four to five inches upwards and the stand is made of wood. Is the BT module in such a bad position that it needs to be on the same level as the mouse? I really would love to use that stand as it makes work so much easier. Cheers.
