How can I use different magic mouses at home and at work? I have two magic mouses, one at home and one at work. Both work just fine over bluetooth with my Macbook Pro (10.9.2), which I use at both places.

Suppose I'm using my home mouse, and then unplug my laptop. If I use my laptop at home next, the mouse with automatically connect. But if instead I bring it to work, the mouse won't automatically connect and I'll have to connect it manually. At which point, I'll have the same problem again: it'll automatically connect to my work mouse, but I'll have to connect my home mouse manually.

This is getting really frustrating. Is there any way I can make both mouses connect automatically?
Afaik what happens to you is not default OS X behavior. It should always connect to any input-device that is nearby automatically. 

You could try the following:


Remove all bluetooth devices from the bluetooth preferences
Delete com.Apple.Bluetooth.plist from /Library/Preferences and/or ~/Library/Preferences (once I had it in both... not sure why)
Reboot
Pair devices again
Reset your PRAM by holding ⌘ Command+⌥ Option+P+R after pressing the power button when turned off. Hold it until the startup-chime is heard for the 2nd time.
