I am using my friends iMac at this moment, and I get a message “Mouse Batteries Very Low – Replace or recharge the batteries soon.”. So I turned this Magic Mouse upside-down and now it turns out that the bottom side is different from my own Magic Mouse… I can’t find the lid to open the Magic Mouse and get the empty batteries out…
What is wrong ?
The Magic Mouse you have yourself is a 1st generation Magic Mouse that does have a battery compartment with normal AA-type (rechargeable) batteries in it.
The Magic Mouse you are holding now is a Magic Mouse 2 (2nd generation) that has a rechargeable battery pack built-in. There is no battery compartment you can open, there is no lid. You just have to take out the Lighting cable from the iMac-keyboard (or get a Lightning-cable equipped USB-charger from your iPhone or iPad) and plug it into the small oblong hole in the bottom of the Mighty Mouse 2 and it’ll start recharging.
I had left my MacBook Pro (Late 2008 running OSX 10.11 El_Capitan) running and had forgotten all about it… after completely recharging everything seemed to be okay on first sight, but it turned out that even though I could use the (internal) trackpad to move the cursor, I wasn’t responding at all to any clicking on it. I therefore had to connect a USB-mouse. Even after restarting, the trackpad was responsive to moving the cursor, but not to clicking…
Is my MacBook’s trackpad broken ? Or is there a software solution I could try ?
Even tough it’s not possible to completely rule out the scenario that your trackpad is broken, chances are you will be able to get it working properly again by an action that is normally referred to as “Resetting the PRAM”. Here’s how to do that :
shut down your MacBook
take out all cables and USB-sticks (this is just to rule out complications)
restart your MacBook using the POWER-button
immediately press and hold the key-combo [CDM]+[ALT]+[P]+[R]
make sure you do so while the screen is still black
when the screen lights up in light grey, you’ll hear the startup-chime
now release all your fingers from the keyboard before the Apple-logo appears
let your MacBook startup fully, then test if all works as expected
then reconnect any cables and USB-sticks needed
Note : no worries if you act too slowly or too quickly ; if you are too late to press the key-combo, just let your MacBook startup, then shut down and try again ; if you keep pressing the key-combo for too long, you will hear the startup-chime multiple times (you will have reset your PRAM multiple times, but that’s no problem) so just release the keyboard, and just let your MacBook startup and you’re done… 😉
