Without OCLP, the latest release of macOS that a 2015 MacBook Pro will run is Monterey (5 releases ago).
The final release of Monterey was July 2024. So no, it is not getting updates anymore. Worse, many programs require a newer release of macOS to run at all.
This is a perfect system to migrate to Linux. It will run faster, be more secure, and will have totally up-to-date software.


Had to upgrade my wife as she could not use Zoom and I think Teams. Plus Office could not get final updates and even Numbers and Keynote wanted a newer version of macOS. I cannot remember what else.
