How can I keep my iMac sleeping while I turn off my mouse?
I want to save on my mouse's battery life, but after putting my iMac to sleep for the night, I turn off my mouse and my computer wakes up. Then I have to try all over again. I've given up turning off my mouse at night. Feel like bead brain - any ideas would be appreciated.
PS I looked in mouse preferences, but nothing caught my eye.
