How to update older Macbook Pro to Mojave 10.14

Back up your data, check the application compatibility table, click here, and then on the download link for a newer OS. That model's maximum one is Monterey.

Catalina and above won't run 32-bit software and split the functions of iTunes up; if you choose one of them, use Go64 as well.

Neither Mojave or Monterey is among the "most recent three" that vendors such as Microsoft and Adobe support; those are now (Sonoma, Sequoia, Tahoe).

However, if you do not have 32-bit applications that you need or want to keep using, you may want to upgrade that MacBook Pro to Monterey. Why?

• Although Monterey can't run the latest versions of Safari, it can run newer versions than High Sierra can.
• Monterey is recent enough to run the current versions of just about all major third-party browsers (Firefox, Brave, Opera, Microsoft Edge, Chrome).
• Monterey is also recent enough to run the current version of the LibreOffice office suite.
