Magic Mouse 2 must be reconnected after each reboot in Bootcamp

I’ll try turning off the wireless. My account, which is all I’ve signed on with, has admin rights. When students eventually sign on, they will not. By the way, this is specifically a Magic Mouse issue. I tested a Dell BT mouse, and it works perfectly.

I briefly thought I had resolved it by going through a series of steps where on the Mac side I removed the mouse, turned off Bluetooth options, then turned off Bluetooth, booted into Windows, removed the mouse and added it back. That worked for most of a day, but then if anyone ever turned the mouse off, it quit working, and it may have just quite anyway--not sure, but in any case, it quit working. In a lab environment used by students, I need something reliable. I can't have class starting and someone without a mouse.

I was using Bootcamp because it's free, and I'm somewhat familiar with it. I've also got several pieces of older Windows software running on Bootcamp, so I'd be a bit leery or jumping into something else that might not run them correctly. I'm sure I won't get any money back...they were all purchased as a unit from Apple. I really wish, especially since other non-Apple Bluetooth mice don't have this problem, that Apple would own it and work toward a resolution, but at this point, I'm just over it. I've been working on this for days and days on end, and I'm going back to the 4 year old wired keyboards and mice.

I can't tell you how much I appreciate that you have tried to help. Thanks so much.

Loner T, I tried the Apple Software update, but it said everything was up to date. As far as Virtual Box, but it's supposedly for personal use, and I am told we got a call from them when this was installed on a bunch of student PCs on campus, so I'm not going that route.

Armstrongbuff, I tried your suggestions. All 31 of these are also Ethernet, so turning off Wi-Fi was simple. I did disable power settings on both Broadcom 802.11ac Network Adapter and Broadcom NetXtreme Gigabit Ethernet. The current version that is installed for the Broadcom over UART driver is version 12.0.1.875, dated 6/21/19. I tried to roll back the driver, but version .874 was never installed, so that didn't work. I tried removing it and just installing the older version, but it wanted an .inf file, and the updated I downloaded from Microsoft Catalog didn't have one, so I was never able to get the older driver installed--and it seems like the newer .875 version would be better, anyway? In any case, none of this made any difference. The Magic Mouse 2 still stops working at each reboot - never any other time--the Dell Bluetooth mouse continues to work without issues.

Thanks again to both of you.

Thanks for your reply. They pair automatically with the Mac/OS when I set up each iMac. I'm using the Bootcamp assistant. The keyboard pairs automatically with Windows, the mouse does not, as normally it would be expected to do. Big Sur 11.1 is current version.

Not sure what we would be testing? Basically I have 31 iMacs and 31 keyboard/mice that don't (or likely won't) work in Windows. I have only set up 10 of them, and all 10 had to have the mouse manually connected in Windows to work. I just assumed that once they worked, they would keep working. I got the 10 ready and set them to the side before putting them in the lab. After I put two in the lab, users were reporting non-working mice, and I discovered I have to reconnect the mouse every time it reboots. I got three more of the 10 and put them back on my bench, and those three are all the same way as well, so I'm pretty much assuming at this point, they will all do this. Sort of setting up a script to run each time it boots up to disconnect and reconnect the mouse, or buying corded mice, I don't have a solution.

I feel fairly confident it’s not the keyboard/mouse, since it’s happening with six different computers, all using six different keyboards and mice. I actually updated all these iMacs to Big Sur—I’m going to get another one out of the box and not update, just to see if that makes a difference. I’ve checked multiple times for any updates on either side, and there are none. I’ll post if they work properly on Catalina. Thanks for your help.

Wanted to update you. I took another one out of the box and did NOT upgrade to Big Sur, but everything was almost exactly the same. The only difference is that at the windows setup screen, the keyboard worked for the Big Sur machine, but neither worked in Catalina. I had to attach a USB mouse to get started in the setup. When I got to the screen where you select the country I noticed the keyboard had started working, but the mouse still was not. Finished setup, still only keyboard worked. Ran the BootCamp drivers I downloaded from the Bootcamp app on the Mac, but that didn't help anything. Removed the mouse in Bluetooth settings, and it wouldn't reconnect until I turned it off and then back on, then it connected and worked, but as soon as I rebooted, it quit working. I made sure all windows updates, even optional ones, were applied. The only Mac update I saw was Big Sur, which I didn't install. Any more ideas? This just shouldn't be this hard.

SW_DVD9_Win_Pro_10_20H2_64BIT_English_Pro_Ent_EDU_N_MLF_-2_X22-41520. I install the Enterprise version, simply because that's what we use on all PCs.

My Bluetooth devices and Bluetooth radio properties look similar to yours. Let me know if you see anything that raises a flag for you.

I continue to appreciate your assistance on this.

Yes, I did both the SMC and NVRAM. I'm up to 8 machines in a row behaving this way. Again, I really appreciate that you're trying to help me. Big Sur update 11.1 is installing right now. It does say something about a Bluetooth update, but that may only be on the Mac side and not impact Bootcamp.

Yes, I can replace the mouse...but I have 31 computers, so I'd have to buy 30 additional mice. I'm already out about $300 buying cable keepers to keep people from stealing the charging cords, plus more to buy remaining locking cables and padlocks to fasten them with--I have a few. Now to have to also buy mice? It's just a shame that Macs are so expensive anyway, and then to have to keep buying additional products just to be able to use them. I realize most people don't need to run Windows, so they don't face all these issues, but some of our software will only run on Windows. If Apple says you can run Windows, then they should support it. They would not help. I REALLY appreciate that you are .

As for the script, I'm working on a batch file with Bluetooth command line tools. I found one that's supposed to work, but it doesn't.
