Why doesn't my wireless mouse connect automatically?

Every time I want to use my wireless mouse (Apple Magic Mouse) with my Macbook Pro, I need to plug in a USB mouse and "Connect" the mouse manually via the bluetooth menubar widget. Is there anything I can do to make this happen automatically?

Solution 1:

If you've paired it before, clicking the mouse after turning it on should do it.

Solution 2:

If you are connecting/pairing for the first time, use a USB mouse/keyboard + trackpad to do the following:-

1. Turn on your Magic Mouse
2. Go to System Preferences from the Apple Menu
3. Click on Mouse
4. Your device should be able to detect the Magic Mouse
5. Click on Connect
6. Once you see a message "Connected", mouse is ready to use.

If you have connected/paired your mouse with your Macbook/computer before,

1. Turn on Magic Mouse
2. After a 2 sec pause, click and it should work.
