Back up your data, check your applications for compatibility, and depending on what you find, click on High Sierra, Mojave, Catalina, Big Sur, or Monterey.
32-bit software won't run in Catalina and newer; download and use Go64 to scan for it. To check general compatibility, click here and look your programs up.
