I've looked up what could cause this and there are several things. But one of them was said to be an old OS (I use Mavericks). Also, upgrading from one OS to another without doing a clean install could cause slow downs because of bloat.

So, my questions are:

1) Can I upgrade from Mavericks to Sierra without getting Yosemite and El
Capitan first?

2) Do I need to upgrade to the original Sierra first and then do the upgrade?

3) How does one do a clean install instead of just an upgrade?

Thanks.
