Mac OS 10.11

Having trouble upgrading from Mac Os 10.10.5 Yosemite on a Mac Pro (late 2013) that has 16GB memory and 264GB storage available. Try to upgrade to Mac Os 11.11 and can't even load the 10.10.5 update. Massage says I don't have the system requirements? Any help or advice would be great.

So, you’re trying to upgrade from Yosemite to El Capitan? That’s not possible anymore, unless 10.11 is already in your list of ‘purchases’. If not, your only option is the upgrade path to High Sierra.
