    OS X 10.10.3.

    My primary environment has been some sort of Unix workstation since the late 80's. I jumped onto OS X around 1999. I've been very happy with it, through a LOT of hardware changes over the years.

    I've been using various copies of the Magic Mouse since 2009. Lately -- probably with 10.10.2, but especially with 10.10.3 -- it looses focus like crazy. It's nearly unusable. I've tried a few different copies, so I don't think the problem is a particular mouse.

    I've wound up using an old Apple wired Mighty Mouse when I get especially frustrated. Works OK, but it's not the same.

    Is there any hope on the horizon?

    Mouse lags are a very common issue since Yosemite.
    I have only found one working solution:
    On all your accounts, disable Handoff feauture (Settings->General) and reboot.

    It works for a lot of people, but you can't use Handoff anymore to continue your mail from your iPhone to your Mac ...
    I have opened a case at Apple Care to show them, they told me they wasn't aware....

    Can you explain what you mean by 'loses focus'?
