I have a Bluetooth mouse (Logitech v270) that I use with my MBP. Whenever I wake my computer from sleep, I have to re-add the mouse as it does not connect with my computer; the common method of moving the mouse around so that the computer knows that it's available does not work for me. I have tried deleting the Bluetooth preferences file and restarting my computer (/Library/Preferences/com.apple.Bluetooth.plist), and I have also tried adding the mouse as a "favorite" in the Bluetooth settings panel. None of these help. Are there any other suggestions that I could try to see if I can resolve this? Strangely enough, I don't have this problem with my Bluetooth keyboard, which I use with the same computer. Thanks in advance!
