@NatalyaD @jalefkowit @jtonline I'm at a point where I'm wondering whether it might be beneficial to put Mint on my 2011 MacBook, and give it to MiL.
She already uses Firefox, so all I'd need is to make sure that's prominent and available and signed in to her account. We'll be able to remote into it if anything does awry, and I can run software updates in the background.
It has no battery, but she never moves her current laptop anyway. And it'll be a damn sight more stable than the budget Windows laptop she currently has.
