I'm trying to update my OS. I currently have Yosemite 10.10.5 on a Mac Pro early 2009. I checked for updates, and there aren't any available. How can I get the OS updated?
Mac Pro
You'd either have to run Software Update (which might not find much) under "About this Mac" under the large Apple icon on the
left hand side of your screen, or go to the App store and look for El Capitan. Upgrading to Sierra or later requires a Metal-capable
video/graphics card, and yes, Sierra will check if there's one in there before trying to install, plus it does a firmware update.
Otherwise, no go

Check your facts. Consider getting a copy of the MacTacker database to save guessing. That MacPro will support up to os10.11.6 "El Capitan."

Fact: Software Updates offers incremental updates (ex 10.13.2 to 10.13.3), not full system upgrades (ex OS 10.10 to OS10.11). Full updates are offered from the front page of the Mac App store if the version is current, and from Apple Support documents is it is not current. Search support for "download <insert System name here>" That how I found the link I posted for the OP.
Fact: We have two older Macs without Metal-capable gfx hardware that are running High Sierra just fine. Mojave requires Metal-capable gfx hardware.capable, not Sierra.
