Downgrading Monterey to Mojave on a reconditioned MacBook Pro

If I buy a reconditioned 13" MacBook Pro which has Monterey OS installed can I downgrade it to 10.14.6 Mojave. I have too many programs etc with use 32 bit and I don't want to lose them. Mojave does all I want on my MacBook.

Thanks

You can install the version of macOS originally installed on the computer by doing a Recovery style boot and then ask the installer to use the original macOS that came with the computer when it was shipped from Apple. If you don't know how to do this ask for more info...this will require an active Internet connection (with either wireless or wired depending on your setup). What is the exact "Model Identifier" string for this particular mac computer? If you don't have it yet, ask whoever you're getting it from for this info so you can then look up what versions of macOS are supported and available for that particular model.


Good luck...
