Chapter in this post:
I am really a fan of the Magic Mouse and have still been using the first model for ages, as I've only bought MacBook Pros for the past few years and you don't get a mouse delivered with it. The Magic Mouse has been my loyal companion for over 10 years when I work at home.
I like the flat shape and above all the possibility of not only being able to scroll up and down on the touch-sensitive surface, but also to scroll left and right or to make the zoom and pinch gestures. This is something that no other mouse offers.
Before properly starting troubleshooting, make sure you've tried the obvious:
Most mistakes can still be made get rid of the world by restarting.
The batteries in the Magic Mouse 1 usually last for several weeks, but sometimes they surprise me with the message "Connection lost" - and not infrequently if I have only been using the batteries for a few days.
The Magic Mouse 2 - with built-in battery and Lightning charging port - can drive the user crazy with this message, because sometimes the status of the Apple mouse switches back and forth between "connected" and "lost connection" several times within a minute.
The problem with unexpected disconnections can be due to the design of the first model of the Magic Mouse. Mac users have been reporting on this problem in forums for years. The reason for this is that the batteries are a little "loose" in the battery compartment of the mouse.
Depending on how you move the mouse, the power supply may be interrupted for a short time, which the mouse acknowledges with "lost connection", whereupon it reconnects immediately.
The solution is free and simple: you switch off the mouse, open the battery cover on the underside and place a sheet of paper on the batteries to cover the batteries. Then you close the lid and see if it helps. The purpose of the paper is to push the batteries more firmly into the holder to prevent wobbling that can interrupt the power supply.
Another reason for the interruption of the power supply could be the springs that press against the negative pole of the batteries in the mouse. If the springs are worn out here, it can also happen that slight movements of the mouse are enough to break the contact with the batteries.
Here you can help yourself with small aluminum plates that you clamp between the battery and the spring. Please make sure that the aluminum blocks do not touch each other.
Problems with the Bluetooth connection can also cause the Magic Mouse or Magic Trackpad to disconnect. As with all computers, switching it off and on sometimes helps. You can do this via System Preferences> Bluetooth or via the Bluetooth icon in the menu bar on the Mac.
For severe cases, I have an article about 5+ ways to fix bluetooth connection problems.
Every now and then I also read that badly shielded USB-3 cables can cause problems with wireless mice and keyboards. The Magic Mouse 1 and 2 are no exception, because they also work via Bluetooth wireless protocol.
In between, a few reading recommendations:
In case you're still unsuccessful in troubleshooting, there is one more thing you can do, which is delete the .plist files that are responsible for the mouse or trackpad. To do this, go to the "Go to" menu in the Finder and then hold down the ALT key (also called an option). Now the entry "Library" appears in the menu, which you call up.
In the library folder you open the folder "Preferences" and there you look for the following files, which you best drag onto your desk so that you can put them back in case of doubt:
If these files have been removed from the Preferences folder, restart the Mac. When you restart, these files are recreated and any file problems are resolved.
If any tips helped you with troubleshooting, I would appreciate your comment.
