I have a "MacBook Air (13-inch, Early 2015)". It is currently using OS X Yosemite 10.10.5. I am pretty sure this is outdated. Computer says "No Updates". Please advise.

Back up your data, check your applications for compatibility, and pick a download link from the Related Article above. They're full-version upgrades and won't appear in the Updates list.

Catalina and newer won't run 32-bit software; download and use Go64 to scan for it. To check other programs, click here and look them up.
