No low battery alerts for Magic Mouse after macOS 26.0.1 update

Since Apple did not remove it, the likely explanation is that there is a 3rd party extension on your system causing an issue. Out of curiosity, what do you see when you click the Bluetooth icon in the menu bar?

Can you see the battery level of the Magic Mouse in the Bluetooth menu or System Settings > Bluetooth?

My Magic devices are all pretty well charged so I can't test notifications, but I do see the charge levels.

You can add one of the Battery Widgets to the Desktop. Will be hard to miss.

There are probably many more pressing issues to worry about in the world than this one ... several "solutions" come to mind":

• I like Owl-53's suggestion, just check the battery level now and then and recharge when needed. How hard is that. Or VikingOSX's routine of charging whenever below 30%.
• One click on the Bluetooth icon shows battery level. Easy to check.
• Simply charge the mouse regularly, say every Sunday night
• Or do what I do ... keep an old Magic Mouse from a no longer utilized computer and charge it so there is always a fully charged "spare" when the "prime" one runs down, switch to the "spare" and charge the other one, which now becomes the new spare. I also have some wired mice I can use while the wireless one is charging.

MacOS Tahoe 26.* will alert you when the remaining battery percentage for the Magic Mouse II dwindles to 6 percent. Same story for the Magic Keyboard.

It is your responsibility to monitor the Bluetooth battery levels from the Bluetooth icon located in the Finder's menu extras location. Correspondingly, recharging the Magic Mouse II can be scheduled while you are either asleep, or not using your Mac. The Magic Keyboard can be charged while you are using it.

By example, when my Magic Mouse II charge level reaches about 30%, I recharge it overnight, or while I am out running errands. A simple scheduling matter.

++ 1 and thank you for the mention 👍

Not only when the mouse or keyboard goes flat pers se but for other reasons

Depends on how many devices you have. Also, for some reason my Magic Mouse is not showing up in the battery widget, yet there's a second generic Magic Trackpad in there (and the charge level doesn't match the Mouse). Odd. The Bluetooth icon in the menu bar does the trick for me.

Yep, I have my Magic Mouse, Magic Keyboard, UPS, AirPods 4, AirPods 4 Case all in the desktop widget and can see the charges at a glance. Easy-Peasy.

But FWIW I do get low battery notifications on all of those in 26.1

I think some responses are missing the point. Sure there can be workarounds. The issue is - prior to upgrading to Tahoe 26.1, the battery level always displayed for bluetooth devices when you clicked on the bluetooth icon in the top menu.

Now, it doesn't, also for me.

If Apple removed that, it seems to be a step backwards when they are a supposed to be one of the top tech companies. For making the investment in a Macbook, one would think one wouldn't have to then add more apps to monitor something like bluetooth device battery levels when the OS versions prior all did that.

Yes we can check it often to see where the battery level is, but that is how we did it before when the battery percentage displayed when clicking the bluetooth icon in the menu.

Correct, I noticed that in the comments, some OS Tahoe do still have the percentage showing, others don't. That is the frustration and it would be nice to know from Apple if there is a why or a fix for those of us who don't. For all the years of having a Mac and bluetooth, any of the OS systems have always shown it.

I have a wired mouse as a backup when the Magic mouse dies or when the magic mouse needs charging.

If this notification bug has been fixed in the .1 update, this is great news and I'll be very happy.

My mouse is currently at 12%, so I look forward to receiving the low-battery warning fairly soon.

• I'm aware that I can monitor battery levels in the bluetooth dropdown, however the charge warning is so helpful if I happen to be deep in work and a charge is needed imminently.

• I know how to charge my devices and I have no complaints about that.

To use the analogy

Does one wait for the car to run out of fuel before they check the Fuel Gauge ?

I've reconnected a Magic Mouse 2 to my iMac to see how long it takes to get to 6%.

Well, it appears to have lost 1% in 2 hrs. So if I left it on and used it 24/7 it appears it will take almost 8 days to get to 6%. I'm not waiting that long to see if I get the warning. 🤷‍♂️

That 6% low battery alert has existed prior to Tahoe, so 26.1 has nothing to do with it.

I also wrote a LaunchAgent a few years back where I could determine how frequently it would automatically check for a low battery condition and the actual percentage threshold where I wanted a vivid dialog to pop onto the screen. I have not tested it recently though, and I only have Tahoe installed on my M4 Mac Mini Pro. It might work on Sequoia and Tahoe…
