Bluetooth not working High Sierra

Hey, guys, how about a "helpful" vote for me?

Happy I could contribute something to this ongoing mess,

Tony

The page does not let me mark your post as helpful. No idea why not.

Tnx.

**** I also cannot connect to my bluetooth loudspeaker. It is very annoying! I'm really considering to change for samsung or lg devices. ****

I have the above upgrade (10.13.4). Two total BT crashes since upgrade. 'Funny' thing is, BT in System Preference shows that BT is ON, although it is NOT. ( Bluetooth sign changed to Unavailable ).

I have called the Apple support ticket but they insist on buying a support ticket - come on Apple seriously?!! This bluetooth issue is awful - offer us a solution!
!

Oh, and please, stop trying to reboot the BT board and restarting your mac... you'll just end up breaking them and they're too beautiful and good to die 😢

I noticed this bug after installing Sierra High in my job's iMac and then I had to find a Windows mouse with a cable to finish setting up and then after updated again from the App Store this trouble has gone...My latest version working fine is 10.13.3

I've had the same intermittent bluetooth connectivity issues too with keyboard, trackpad and headset on my 2011 MacBook pro. I just installed the latest 10.13.2 update which didn't seem to fix it (yet). This fix works for a while - but I've had to do it several times:

1. Hold down Shift + Option keys, go to the bluetooth icon in the menu bar you'll see a "Debug" option
2. In the sub-menu choose "Remove all Devices"
3. then after that, choose "Reset Bluetooth Module"
4. Shut down the Mac (not restart)
5. Restart the Mac
6. Reconnect your bluetooth devices

It's a pain in the @$$ to keep doing, but it works.

Hope this helps

Having the same problem on iMac 2017, OSX 10.13.2. Loosing Bluetooth connection intermittently. Always have a cable bound mouse connected now to deactive/activate Bluetooth. Sometimes however, my Mac thinks that there is no Bluetooth at all, so I need to reboot.

This is more than just annoying and should be fixed by Apple ASAP!

Ok, I seem to have found a solution to my problem regarding the mouse not connecting...this has worked for both me and my wife.

So when your mac is on sleep mode and you hit a key to wake it up, you are then on the screen to log in, this is when you need to click your mouse so it connects (before you type your password)

Problem solved 😉

Apple doesn't want to take responsibility for this. Instead they act like we're all just insane. They literally even changed hardware in my new iMac and that didn't fix it. The only fix? I went back to Sierra well over a month ago and ironically NOOO ISSUES SINCE. The only issue is now my computer CONSTANTLY wants me to upgrade. Sad to see so many are still having the same problem as I have to scan this to see WHEN I CAN ACTUALLY upgrade again. Sad.

I guess I have the same issue with my Magic Mouse:

Sometimes, it disconnects, sometimes macOS looses BT completely, and at least once I had two entries for the single mouse I have (none was working).

After reboot, the mouse connects again - but I didn't become an Apple customer because I want to fix problems with reboots and fresh installs.

I was wondering if it is a combinatorial problem.

The iMacs in my Apple Store are all operating fine with magic mouse and latest High Sierra 10.13.4 OS.

So it might just be that we have a 'weak' bluetooth module that is exposed by changes to the bluetooth module.

Or the bluetooth module in combination with equipment near the computer.

Update on this - after an update of OSx last night on machine, today a new message suddenly popped up in the middle of the day declaring that my keyboard was operating via a wired connection. I tried the magic mouse and it connected straight away - unpliugged the keyboard and same. And they have stayed active via a number of power offs (to sleep).

I just got the feeling that the new message might indicate some activity in keyboard/mouse support. Will post further later.
