Good afternoon, my MacOS need to upgrade to 10.16 to file my Tax Return,
How do I upgrade my system to macos 10.16
Back up your data, check the application compatibility table, click here, and if your Mac model is recent enough, then on the download link for a more-recent OS. There isn't a 10.16; Big Sur is 11.0.
Catalina and higher won't run 32-bit software; if you upgrade to one of them, use Go64 as well.
