Microsoft and possibly also Apple software will also run on the platform.

Well, I can actually think of a few, but it never hurts to make sure your Apple software is running smoothly.

What this doesn't mean is that Apple software is the highest risk.

But to me, coming from that other world, upgrading Apple software feels almost redemptive.

Apple software being more secure than Windows has always been a myth.

Using Apple software could be one way to do it.

It feels like Apple software, actually: slick, intuitive and a lot of fun to use.

But not everyone lives on Apple software alone, and here's where things get more interesting.

And it does not only collect info about Apple software.

There are no "upgrades" with major versions of Apple software anymore.
