Bluetooth connectivity issues

As just said above, this is as much an issue with third party manufacturers who make USB devices/cables without proper shielding.

Like other users, I am having the exact same problems with the MacBook Pro 15" 2018 as well. There's several threads on the issue. It's absolutely nauseating having to have disconnects sometimes several times a minute, sometimes 'only' several times an hour. Both V1 magic mouse and keyboard have been working, and still do work, perfectly on my MacBook Pro 2013 and on other computers. It's the 2018 generation that Apple seems to have used some flawed bluetooth module in I assume.

Buster, all my cables ARE Apple cables! These are the very same cables I use on my MBP with absolutely no issues. Apple confirmed my first Mac Mini 2018 was faulty. Your assumptions are incorrect. However, I have found a way to minimise the loss of keyboard and mouse connection and that was to change the router channel from 8 to 1. Today I ony lost connection to my keyboard once, and that was just for a few seconds. Let's be frank here, there is a problem and inteference from non-Apple cables is bullsh*t - the bluetooth and wifi modules inside the mac mini should be able to cope with this. It's all utterly rediculous, even my nasty PC can run run the same hard drives I connect to my mac and connect flawlessly to my bluetooth keyboard and mouse without any issues at all.

Hi, tburzio !

Given these forums have - through a lot of effort and testing - proven there are two main causes of the bluetooth/Wi-Fi problem:

1. EM interference
2. Android File transfer app

and given that both are not under the control of Apple, exactly how did you arrive at the unsubstantiated claim this is an Apple internal problem? I ask because for you to have any actual first-hand knowledge would mean you are violating your Apple NDA. That is a bold, foolhardy move to do on Apple forums. It should be child's play for Apple Security to track you down. It also means if you don't have any actual first-hand knowledge then you just posted a made-up lie.

So please - tell us in detail which it is.

Have you been able to discover the connection between the USB-3 hub and the BT issues? Is it radio interference? If so, doesn't it tell you something about Mac mini's FCC-MANDATED ACCEPTANCE OF interference?

Fixed that for you.

Gotta agree there, JJWWMM.

After 2 weeks of abject frustration with a brand new 2018 MBP Pro, that would constantly cut connection to my earlier generation Magic Mouse & Keyboard, that's what I did, too - completely erased all my hard disk and reinstalled everything from scratch - after a re-install of just the OS X didn't help.

It's been working since. I also splashed out on a new 5 GHz capable router too, tho, as some have claimed overcrowding of Bluetooth 2,4GHz frequency. This might also have helped the cause, who knows.

Quite relieved I managed to contain the problem after all! And yes - setting it all up again took me 2 full days.

Just bought the new Mac Mini, spent most of the day yesterday setting it up only to find the same issue with the Bluetooth connection. In my case i am using a Logitech K780 keyboard which does not connect on startup which means that i am unable to type my password in??? Also have a magic mouse which kept disconnecting and then reconnecting all day.

This is not what i expect from Apple and if i am not able to resolve the issue within the next day or two will return the unit and purchase something else.

I am so disappointed with the BT issues-- I have had to remove most of my USB devices and finally got the mouse to work most of the time. Tonight I tried my EarPods and they work as long as i am less than 2 ft from my computer. If I lean back in my chair or go to the printer a few feet any the connection is lost. I also tried my new Beats Studio headphones and BT works but in a very short space. With my old iMac I could wall around the office with both of these. I have a fully loaded $4000 system that can't run wireless music devices---JUST GREAT.

I can't see how software can fix this. There needs to be a hardware fix.... No comment from Apple. They are better than this

Sorry, I would say maybe it is just a matter of time. MacOS 10.14.4 did not help me at all. I kind of feel like it got even worse.

My main problem is with airPods. You never want to listen to anything on your macMini with your airPods. If disconnection of your Magic Mouse is disturbing, a continuously skipping sound in your ears is unbearable. I tried every single thing suggested here, discussed countless hours with 5 different Apple advisers and I am still right at the same point where I started with my in retrospect, ill advised purchase 5 months ago. Apple is satisfied keeping me frustrated and unsatisfied, they won't accept a return.

I disconnected everything in my office and only had a Mac mini and a monitor and still had Bluetooth issues and a range of about a foot for my AirPods to work. Even when I didn’t move my head the signal to the AirPods would be broke. The keyboard usually works for me since it is close to the Macminin but the mouse disconnects all the time since I move that further away from the Macmini

So just as bad (?) as mine. Would love to know comparison values from a working non-MacMini.

By the way: I have now tried to disabled the Mac's WIFI connection and use ethernet instead. Will see if this has any effect.

I’ve had WiFi off for a long time, and I still have mouse problems IF I start 3D number crunching and the internal fan spins up. I still think it’s a power shortage, and the Bluetooth hardware is specially sensitive to a brownout.

If it is indeed interference from a 2.4 GHz. router that might be fine for some people but some of us have many devices that still do not support 5GHz. In my network I have several devices (mostly home automation) that only work on 2.4 GHz. so shutting off that part or the router is not an option.

I am still looking for a wired mouse that replicates the swipe functionality of the Apple Magic Mouse. The Magic Keyboard works as a wired keyboard since i can just leave it plugged into the Lightning cable but the Magic Mouse does not since the connector placement prohibits it.

There is a new MacOS out, has anyone tried it yet to see if this addresses the problem?

I'm giving it a try right now. I'm not sure which unsatisfactory solution is slightly less unsatisfactory: using it as a wired device or turning off my Mini's wifi.
