Update OS Version
How Do I update my Macbook pro from version 10.11.6 to version 10.15.0 or later.
MacBook Pro 13″, OS X 10.11
Back up your data, check your applications for compatibility, and depending on which MacBook Pro model you have, click on Catalina, Big Sur, or Monterey; it needs to be at least a 2012 one to run any of them. If you get a Mac App Store preview page, change the https at the beginning of its address to macappstore.
Catalina and newer won't run 32-bit software; download and use Go64 to scan for it. To look up other programs, click here.
