Can't pair 3rd-party Bluetooth Keyboard on Mojave (10.4.6)

(oops I replied to myself, I meant to reply to @fmaclen)

Do you have Logitech Options installed? I also have it and I was wondering if it's the thing that causing the trouble.

Logitech Options download page says that the current version 7.14.77 works on Mac OS X 10.14.x, so it seems like it's supposed to be compatible, though the last release was before the launch of 10.14.6 on 2019-07-01. I got the notification for the update right before the OS update, but I updated OS first and Logitech Options later. (Can't quite remember if bluetooth devices stopped working right off the bat, or only after updating Logitech Options.) How's your situation for installation? By the way, I removed Logitech Options using the official uninstaller, but after the reboot and another NVRAM reset, anything didn't change at all.

My bluetooth menu won't even show the other non-Logitech keyboard but only shows my Logitech mouse, and I don't know if it's possible that this software messed it all up this bad, though I thought it just might be possible? This guy in another thread seemed to have some sort of peripheral issue after the same update, and he also has Logitech application installed (though seems like it's USB cam but not bluetooth).

I'm asking around in different places online but I see nobody else claiming the issue, and no help whatsoever. At this point, we aren't exactly sure if this is caused by the OS update neither. However, probably that's what it is.

I'll rollback to the previous working version (10.14.5) IF I HAD TIMEMACHINE BACKUPS enabled. If you do have one, rollback to that version and stay safe until the next patch shipped from either Logitech or Apple (or any third party app that you use for that Surface keyboard).

I can't do this and I don't want to rollback as far back to 10.13.x, so I'll just back up the whole disk and start from fresh install of this newest version of macOS. I'll report back how it turned out. I think I'll try that this weekend!

I have the same exact problem with

• 3rd party keyboard (HHKB Professional BT; compatible with macOS 10.5 and later)
• 3rd party mouse (Logitech MX Master; compatible with macOS 10.10 and later)

and both of these has been fully working for the last 3 years, almost every weekdays,

This started right after the update to version 10.14.6 from 10.14.5 which has been working for more than a month using literally every weekdays with the exact same device.

These are supposed to be compatible with macOS, but I suppose it's not checked with 10.14.6?

Two manufacturer at the same time?? I doubt it and I think it's failure on the OS side.

Hello fmaclen,

Thanks for reaching out.

Based on the information you provided, the keyboard may not be compatible with Mac, period. Have you checked the manufacturer's documentation for which hardware products they support?

P.S. Mojave is 10.14 not 10.4

Good for you, and thanks for letting me know! Sadly, it wasn't the case for me, so I'm giving up.

I've been in that mode since the beginning, yet I get the same result. Check back the user's manual for the devices and there were only one way to get it to pair (of course), and it gives this result. Machine forgot these devices so it should be the first time to pair these things, so I don't know what else to do. (For another device, it still won't even show up on the list.) What makes the matter even worse for me is that, these Bluetooth devices works just fine on another updated laptop.

So I must guess that there's some unique situation happening on my laptop. Probably I'm the only one on the earth complaining this.. I suppose I need to flush the system and try again. Hopefully it's not physical issue but just some software bugs relating to some special software configuration that I'm not very aware of.

Anyhow, congrats!

I have a similar problem following the upgrade of my mid 2015 MBP to 10.14.6 this morning. I am no longer able to connect my Magic Mouse. Indeed sporadically I am unable to switch bluetooth on or off. My mouse no longer appears in the list of devices. Seems like a widespread problem, I've tried every fix that has been posted in various threads online but to no avail.

Contact the keyboard's developer for help. These forums are limited to Apple products and services.

Third-party products have to be made compatible with macOS, not the other way around. Hence, why you contact the third-party developer for help, not Apple.
