Need to update OS X version

Hello all - My computer is telling me "to use your iPhone with ITunes, you need to install OS X 10.11.4 (or later). I currently have OS X Yosemite 10.10.5. How can I go about doing this? Thanks for the advice!


iMac 27″, OS X 10.10

Back up your data, check your applications for compatibility, and depending on which Mac model you have, download High Sierra, Catalina, or Big Sur through the links provided.
